# FEATURES

24-bit Analog-to-Digital and Digital-to-Analog Converters.

Highest quality AD/DA converters in WaMi Rack 24 provide 120dB of dynamic range and unmatched sound quality with exceptionally low noise.

4-In/8-Out Balanced or Unbalanced Analog Audio Inputs and Outputs.

WaMi Rack 24 provides 1/4¡± TRS phone jacks for use with either the professional +4dBu nominal level professional audio equipment or -10dBV nominal level consumer audio equipment. In either case, you can use unbalanced connectors as well. For cleanest possible audio signal paths, you¡¯ll never need to adjust levels. Unlike some audio interfaces that deliberately boost their output levels to give you a false sense of audio quality, WaMi Rack 24 give you a true indication of your levels. What you hear is what you get. Nothing¡¯s added or taken away unless you intend to do so. If you need to adjust levels, digital level adjustment is provided for Line/Mic inputs.

4 Channel Recording and 8 Channel Playback

You can record analog and digital sources simultaneously and play them back simultaneously as well.

Up to 4 Card Link Support for Multi Channel In/Out

You can use up to 4 WaMi Rack 24¡¯s simultaneously (if you have enough PCI slots) for Multi channel operation.

24-bit S/PDIF Coaxial/Optical Digital In & Out

Unlike some audio cards that claim 24-bit capability, WaMi Rack 24 offers true 24-bit S/PDIF digital inputs and outputs. There¡¯s no additional conversion process for signal already recorded in 24-bit format. With optional Dr. D audio interface/converter, you have access to XLR type AES/EBU Input and Output simultaneously.

32-bit Internal Resolution

With ASIO 2.0, GSI/F, and EASI driver supported software, you can transfer digital audio data at a maximum 32-bit internal resolution. It allows for much greater dynamic range when you are working with digital audio.

Digital Output Type Selector

With the recent adaptation of IEC958 as the standard in professional digital audio, WaMi Rack 24 is currently the one of the few audio interfaces that supports IEC958 Type I AES/EBU format.

Built-in digitally controlled Mic Preamp

WaMi Rack 24 provides 4 channels of mic preamp. If you click Mic On on the control desk, WaMi Rack 24¡¯s input port accept mic signal which is much lower than normal line level and boost it. WaMi Rack 24 also provides ¡°Phantom Power¡± which needs to use condenser microphones. When you click ¡°Phantom Power¡±, it supply 12V of DC power to the connected microphone. You can adjust the Mic input level digitally, using level knobs on the control desk. This will eliminate possible noise appearance caused by loosen physical level knobs.

Word Clock Connector

If you are working in professional digital audio, word clock is not just an additional feature, but a necessity. WaMi Rack 24 contains BNC type word clock input and output port which you can use to synchronize all your digital audio equipment. It provides both the normal Fs, as well as the superclock 256xFs format.

Multiple Sample Rate Support

Supports all denomination of 44.1kHz or 48kHz standard sample rates from 32kHz to 96kHz (32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz and 96kHz). WaMi Rack 24 can be used in a variety of applications ranging from multimedia and audio production to DVD production.

Real-time Hardware Sample Rate Conversion

Regardless of the type of sample rates, WaMi Rack 24 automatically converts the incoming digital audio signal to the sample rate of your choice in real-time.

Uses 32 Bit PCI Slot for PCI Bus-mastering Support

Already appreciated by many users of WaMi Rack for its PCI bus mastering quality, WaMi Rack 24 use only small amount of system resources. Other audio/sound cards can use up more than 30% of system resources, which ties up the computer¡¯s CPU. WaMi Rack 24 operates independently from the CPU, which allows you to use more software plug-in effects without placing a heavy burden on the CPU.

4 In/4 Out MIDI/SMPTE Interface

As its name implied, WaMi Rack 24 provides 4 In/4Out of MIDI channels as well as SMPTE reader/generator with 1/4¡± mono jack SMPTE In/Out port. This combination of audio interface and MIDI interface gives WaMi Rack 24 the position as a true total DTMP solution.

## Handling Electronic Devices

### Avoid Static Electricity

The WaMi PCI card is packaged within a protective anti-static envelope, which prevents static electricity from damaging its delicate electronic components. It¡¯s a good idea to keep this envelope around; whenever you need to ship your card or to store it outside your computer, put it back in its envelope.

Before handling the card, always discharge any static electricity from your clothes and body by touching a grounded metal surface, such as the case around your computer¡¯s power supply. After doing this, use one hand to hold the card by the metal panel (where the parallel cable attaches), and touch the power supply again with your other hand. While working with the card, avoid moving around on carpeted surfaces-shuffling your feet on a rug is almost guaranteed to build up a static charge. If you need to walk around in the middle of working with the card, just repeat the static discharge procedure before touching the card again.

It¡¯s also advisable that you do not wear static clothing, such as heavy sweaters or furs. Even a tiny little jolt of static electricity - like the kind that makes your hair stand up when you brush them – can damage your audio card.

###

### Hold the WaMi PCI Card by its Edges

Always hold the WaMi PCI card by the edge of the card, or by the metal panel where the parallel cable attaches.

l Do not touch the electronic parts!

l Do not touch the PCI slot pins!

l Do not touch the bottom of the card where the circuits are laid out!

## Installing the Wami Rack 24 PCI card in your computer

Before you begin the installation, please consult the manual of the computer for detailed instructions on installing add-on cards in your computer.

1. Shut down the computer and all other hardware devices connected to your computer. Leave the power cable attached to your computer, if you will be using the computer¡¯s power supply as the grounding outlet. Otherwise, upplug the power cord too.

2. Remove the computer¡¯s main cover to expose the available PCI slot.

3. Ground yourself by touching a grounded metal surface (such as power supply of the computer). Ground yourself as often as necessary, especially after you¡¯ve been walking around carpeted room. Read and follow the instructions on ¡°Handling Electronic Devices¡± if you haven¡¯t already done so.

4. Choose an available PCI slot and remove the cover plate (and a screw that holds it in place) from the port on the back of the computer. Cover plate is just a piece of metal or plastic plate, which covers the back end of your computer¡¯s PCI slot. When removed, this side will expose the I/O port of your PCI card. For WaMi Rack 24 PCI Card, the parallel port connector will replace the cover plate.

5. Before handling the WaMi Rack 24 PCI Card, make sure once again that you are properly grounded then remove the card from its protective envelope.

6. Align the WaMi Rack 24 PCI Card with the selected PCI slot. The parallel port panel should line up with the opened cover plate port on the back of the computer. There should be a guide on the back end of the computer to hold the bottom edge of the card in place.

7. Press the card gently but firmly into the slot until the connector is fully inserted. Don¡¯t force the card into the slot and never bend it in any way. If card isn¡¯t snugly fit, pull the card out and try it again.

8. Using the screw removed from Step 4, screw it back on the card¡¯s parallel port plate to keep it from moving. It must be tightly and firmly screwed on.

9. After the card is installed, replace the computer¡¯s main cover.

10. With the card installed, you should proceed immediately to install the necessary software.

11. Hook up Wami Rack 24 cable to main unit from PCI card using 44-pin connector.

5.BAL

Select it if you are using balanced lines. Balanced lines are wired 3 connections, such as XLR connectors or 1/4¡± TRS (tip-ring-sleeve) phone jacks.

6.Gang Mode

Links the L-R knobs for stereo operation. Deselect the Gang Mode if you need to control the left and right levels independently.

7.MIC ON

By checking these buttons, the input ports of WaMi Rack 24 are enabled to accept and boost microphone signal, which is much lower than line level signal.

8.Phantom Power

When you use the microphone that needs phantom power, such as condenser microphone, you can get it by clicking these buttons.

) MIC PREAMP mode will be working in pair. i.e. Input 1,2 and Input 3,4will be affected simultaneously when you choose ¡°MIC ON¡±

DIGITAL INPUT with SRC (Realtime Samlple Rate Converter)

ON/OFF

WaMi Rack 24 can function as a real-time sample rate converter. SRC stands for Sampling Rate Converter and this is the unique function of WaMi Rack 24 that you can not find from any other digital audio interface. You can change the incoming digital signal to the different sample rate by choosing Internal word clock >click ON button to enable the function > selecting a desired sample rate. The maximum conversion ratio is 3:1, for example, if the input signal is 11kHz, then you can convert it up to 32kHz. On the contrary, 96kHz input signal can be converted down to 32kHz.

IN-3,4 SELECT

Though the input 1,2 of WaMi Rack 24 are fixed to Analog input 1,2, you can still select input signal for the input 3,4. In this section of the Control Desk, you can choose the input signal for the Input 3,4.

### 1. A NALOG

Selects the input device connected to the Analog Input 3 and 4 (1/4¡± phone jacks) on the back of WaMi Rack 24 as the input signal to route to your audio recording (or monitoring) software.

### 2. C OAXIAL

Selects the input device connected to the Coaxial (RCA type) Digital Input on the back of WaMi Rack 24 as the input signal to route to your audio recording (or monitoring) software.

### 3. O PTICAL

Selects the input device connected to the Optical Digital Input on the back of Wami Rack 24 as the input signal to route to your audio recording (or monitoring) software.

When one of the Digital Inputs lights in green, it indicates that the Coaxial or Optical is selected for DIGITAL IN clock source. Even though you are not using the digital input still you can use the digital ports as the master clock source input.

WORD CLOCK

Selecting the Word Clock is necessary if you have selected Word Clock as the CLOCK SOURCE (explained below). Depending on the type of word clock sample rate of the digital audio device you are synchronizing to, you¡¯ll need to choose either Fs or 256x Fs. Check the manual of the device as to the type of word clock it uses. For example, most Digidesign Ô products uses 256x type. Many other broadcast and professional digital audio equipment also use 256x type.

### 1. Fs

Select this option for most word clock synchronization applications. Unless your digital audio device specifies that it uses 256x Fs word clock, you should select this option. Check your equipment manual for details.

### 2. 256 x F s

Select this option if you need word clock synchronization with Digidesign ä products and other digital audio equipment using 256x word clock sample rate. Check your equipment manual.

CLOCK SOURCE

Clock Source is where you choose the source of word clock for digital audio recording or playback. If you don¡¯t need to synchronize your computer and WaMi Rack 24 with other digital audio hardware, such as digital recorders, digital mixers, and etc., select Internal Clock. Otherwise, you will need to set the Clock Source as explained below.

### 1. I NTERNAL

Selecting Internal makes your computer¡¯s clock the master word clock. If you don¡¯t need to synchronize the digital audio software on your computer with other digital audio devices, choose this setting. To use SRC, you should select Internal for Clock Source as well.

### 2. D IGITAL IN

Most S/PDIF devices don¡¯t have a separate word clock input or output. When recording, they use the incoming digital audio data as the clock source, and automatically use their internal clock when playing back. By selecting Digital In, you will be using the incoming digital audio data as the clock source. Choose this setting if you are recording from DAT or CD¡¯s equipped with S/PDIF output, but without a separate word clock output.

### 3. WORD C LOCK

When selected, the device connected to Word Clock on the WaMi Rack 24 will be the word clock source. If you are recording from a digital audio device equipped with word clock output, connect a BNC cable between that device and the WaMi Rack 24 Word Clock. This allows the sample rate to be controlled by the word clock of the device you are recording from.

### 4. WaMi to WaMi

It will allow up to 4 WaMi Rack 24s to function in full duplex mode. You can connect WaMi Rack 24s by connecting PCI cards internally. For the physical connection between WaMi Rack 24s, use 2-pin header connector on WaMi Rack 24 PCI card. There are two connectors named as ¡°Sync In¡± and ¡°Sync Out¡±. Connect Sync Out to Sync In of another WaMi Rack 24¡¯s PCI card, first unit will be the master device and the unit that accept the Sync would be the slave device.

Digital Output Type

Digital Output (IEC 958) Type selector determines the type of data format to be used on the digital output jack of WaMi Rack 24

1.CONSUMER ( IEC 958 Type II )

Generally known as S/PDIF (Sony Phillips Digital Interface), select this mode if you are sending digital audio output from WaMi Rack 24 to a S/PDIF equipped audio device.

2.PROFESSIONAL ( IEC958 Type I )

Generally known as AES/EBU, select this mode if you are sending digital audio output from WaMi Rack 24 to an AES/EBU audio device.

Important Notice: Since the adaptation of IEC958 no longer distinguishes between S/PDIF and AES/EBU, some of the older AES/EBU audio equipment require a higher signal level than WaMi Rack 24¡¯s digital output levels (which conform to IEC 958 standards). If you experience problems transferring digital audio from WaMi Rack 24 to an AES/EBU equipment, you may need a signal converter such as EGO SYS¡¯s Dr. D to boost the level.

SAMPLING RATE

Sampling rate can be set manually to three standard settings or automatically set through audio software you use. In most cases, it¡¯s safe to leave it in Auto Set mode so that you can use your audio software to control the sampling rate. Sampling rate selection has no effect during playback. WaMi Rack 24 automatically detects it.

1. 32

Sampling rate is fixed at 32,000 Hz (32 kHz), which is digital audio broadcast standard.

### 2. 44.1

Sampling rate is fixed at 44,100 Hz (44.1 kH z), which is CD-audio standard.

### 3. 48

Sampling rate is fixed at 48,000 Hz (48 kHz), which is commonly used for digital audio mastering.

### 4. 64

Sampling rate is fixed at 64,000 Hz (64 kHz).

### 5. 88.2

Sampling rate is fixed at 88,200 Hz (88.2kHz)

### 6. 96

Sampling rate is fixed at 96,000 Hz (96 kHz), which is the highest sampling rate value.

7. AUTO

Sampling rate is automatically set by the selection you make in your digital audio recording software during analog audio recording, and by the encoded signal format during digital audio recording. The default is 44,100 Hz during analog audio recording.

INPUT MONITOR

Input Monitor is where you will select which Analog Output you will use to monitor the Input Sources. While most digital audio recording software provide input monitoring function that allow you to monitor the input source through the software, not all do and some have quite a bit of time delay. By selecting an Input Monitor on WaMi Control Desk, you are electing to monitor the input signal at the WaMi Rack 24, instead of through the software. This has some advantages and disadvantages. On the positive side, there is virtually no time delay between the actual input signal and the monitoring signal. The major disadvantage is that you can not monitor the plug-in effects or level changes you make in your audio software.

### 1. OUT 1,2

Selects Input1,2 and/or Input3,4 to Analog Output 1, 2 as the Input Monitor Port.

### 2. OUT 3,4

Selects Input1,2 and/or Input3,4 to Analog Output 3 and 4 as the Input Monitor Port.

### 3. OUT 5,6

Selects Input1,2 and/or Input3,4 to Analog Output 5 and 6 as the Input Monitor Port

### 4. OUT 7,8

Selects Input1,2 and/or Input3,4 to Analog Output 7 and 8 as the Input Monitor Port

5. Monitor Off

If you don¡¯t select any input, basically the Input Monitor mode is off.

On the WaMi Rack 24 PCI card, there is a 2-pin connector for CD-ROM digital input. This input directly connected to the digital output port (RCA connector) on PCI card bracket¡¯s surface. If you want to connect CD-ROM¡¯s digital output to a device or the WaMi Rack 24, you can use this port for the purpose.

) CD-ROM connection

1. Connect from Digital Out of CD-ROM to CD-In 2-pin header port on WaMi Rack 24 PCI card with provided 2-pin header connector.

2. Connect CD-Out port on PCI bracket to S/PDIF Coaxial Input port on rear panel of WaMi Rack 24.

3. To monitor audio CD, select COAXIAL for ¡°IN3,4 SELECT¡± and select 3,4 in ¡°INPUT MONITOR¡± for desired output.

MIX MODE

When more than one output source is selected to be played back simultaneously in the Input Monitor, you are actually combining the data of two or more digital audio signals together, resulting in an overall gain of about 6dB/bit for each signal combined. This can cause the output circuit to overload and create a noticeable click or distortions as the combined level can exceed 0 dB peak level. Mix Mode gives you the choice as to how such excessive levels are handled by WaMi Rack 24

1. DYNAMIC

WaMi Rack 24 will not adjust the combined signal level. In this mode clipping signals are audible, but left untouched. If you want to adjust the levels, you can do so by adjusting the levels from the audio software

2. SOFT

The combined signal levels are reduced automatically by WaMi Rack 24, depending on the number of signal sources combined. For two combined signals, the output signal is reduced by –6 dB. When three or four signals are combined, the output level is reduced by –12 dB.

OUTPUT LEVEL

You can select the output level of WaMi Rack 24 through analog output ports. Selection must be matched to the reference level of input audio device. Normally, ¡®Professional¡¯ devices accept +4dBu/Balanced input level and ¡®Consumer¡¯ devices accept –10dBV/Unbalanced input level. Mismatching level may cause overload or too low to use signal level.

1.+4dBu/BAL

Sets the nominal output levels to +4dBu for professional audio applications.

2.-10dBV/UNBAL

# SMPTE Control Software

For those of you not familiar with SMPTE (Society of Motion Picture & Television Engineers) time code, there are many good reference readings on the web. Basically, the SMPTE time code used most widely in audio applications is the longitudinal type, which converts time data to into audible signal. With controlling software and hardware (such as the WaMi Rack 24 and SMPTE Desk) SMPTE time code allows 2 different devices to be lock in time. For example, a multitrack recorder can be synchronized with a MIDI sequencer by generating a time code and recording it on a track of the recorder. A recorded SMPTE time code is then read by a SMPTE reader (such as WaMi Rack 24) and converted into MIDI time code, allowing the MIDI sequencer to lock on to the speed of the multitrack recorder. For more details, read APPLICATIONS-SMPTE SYNCHRONIZATION on page 19.

SMPTE Desk is the WaMi Rack 24 control software for SMPTE time code generating and synchronization. SMPTE desk will be opened when you open the WaMi Rack 24 control desk. Although it appeared with WaMi Rack 24 control desk, you can show or hide it by clicking SMPTE DISPLAY button.

# Applications

## Basic Audio Connections

In a basic digital audio recording system, you may have at least the following equipment:

1. Line mixer (analog or digital recording console with at least 2 bus output)

2. 2 track digital master recorder (DAT or CD-RW, preferably with S/PDIF ports)

3. 2 track analog recorder (cassette or 1/4¡± reel)

Y In addition, you may have a digital mixer. If you have a digital mixer with optical S/PDIF Input and Output, you may want to make the additional connection show below in gray lines.

## SMPTE Synchronization

### SMPTE Primer

SMPTE synchronization allows two or more devices to be electronically locked in time so they will function as if it was a single device. For example, your computer MIDI sequencing software can be synchronized with a multitrack tape recorder (MTR). In more advanced post-production applications, you can synchronize a VTR with an MTR, allowing you to lock soundtracks to the picture. With WaMi Rack 24, you can synchronize virtually any tape recorders and VTR¡¯s to your computer¡¯s digital audio software or MIDI sequencing software.

There are basically two types of time code. The longitudinal (or horizontal) time code is the one most commonly referred to as ¡°the SMPTE time code¡±. It¡¯s basically an audible stream of pulse bleeps that contain time data. The other variety, called the VITC (Vertical Integrated Time Code), is another form of time code that can be interlaced with video signal on most video tape recorders.

SMPTE time code is relatively easy to understand and use if you know how it functions. Think of time code as very accurate digital alarm clock that displays in a 24-hour clock base down to seconds and frames. Frame is a sub-division of 1 second. When you generate a time code from WaMi Rack 24, it translates that clock data into digitized square wave pulses, which can be recorded like any audio signal.

What you now have is a reference time data that can be used by both machines that you want to lock together: one that contains the time code and the other that can read and follow the time code. In any synchronization, there is always only one Master and one or more Slaves. Master is the device you will mechanically control. For example, if you want your MIDI sequencer to follow an MTR, your MTR is the Master and the MIDI sequencer is the Slave. The Slave always ¡°Chase¡± the Master.

In order to use WaMi Rack 24¡¯s SMPTE synchronizer, you¡¯ll need at least one device that can CHASE the SMPTE time code. Your MIDI sequencing software is the most obvious choice. This means you can slave your MIDI sequencer to virtually any tape decks, but not vice versa: not all tape decks can chase your MIDI sequencer, unless with a special external synchronizer. Alesis ADAT¡¯Ô s equipped with BRC Ô can chase your MIDI sequencer, but most others require a professional synchronizer.

As in such cases, and in a more complex situation, you may have two devices, in which neither can chase a time code data (e.g. an analog MTR and a VTR). In such cases, an external synchronizer is usually needed to control both machine¡¯s mechanical functions and electronic functions. Here, both machines are stripped with SMPTE time code and are referenced by the synchronizer. The synchronizer constantly compares the time data on both machines to see if they are on right speed. If neither moves away from the other, synchronizer sends electronic signal that mechanically control the speed of the machines. Basically, it tells the slave machine to speed up or slow down to keep in pace with the master machine accordingly. These synchronizers are usually very expensive and not all devices can be synchronized. They need constant software updates as new equipment models are released and changed. As much as we would like to be, but WaMi Rack 24 is not one of these ¡°expensive¡± synchronizers.

In order for the two devices to work together in time, they will need a common time reference, such as SMPTE time code. Since virtually all MIDI sequencing programs used today has the ability to chase to SMPTE time code, why would you need something like WaMi Rack 24 with a SMPTE Synchronizer? The problem is these sequencing software don¡¯t actually lock to SMPTE time. Besides, how would you plug a cable into your computer¡¯s software? Thus, there is a need for an interface. In reality, your MIDI sequencing software locks to MTC, or MIDI Time Code, not SMPTE time code. WaMi Rack 24 has the ability to translate SMPTE time code into MTC, which can be recognized by your MIDI sequencing software. WaMi Rack 24 also has the ability to generate SMPTE time code, so you can record (¡°stripe¡±) a master, such as an MTR or VTR, with a SMPTE time code. Once you have a master device containing a SMPTE time code in it¡¯s audio track, it¡¯s just matter of telling your MIDI sequencer to chase that time code.

### Synchronizing MIDI/Digital Audio Software

#### Generating and Recording SMPTE Time Code

1. Connect a 1/4¡± phone cable from the WaMi Rack 24¡¯s SMPTE OUTPUT jack to any audio track of an MTR or VTR. It¡¯s best to use the most extreme edge tracks if you have an analog MTR.

2. Generate a SMPTE time code reference using the SMPTE Desk.

Choose the frame rate. Usually 30 frames/second is a safe choice. You may choose any, but most audio production work is done in 30 Fs and it¡¯s easy to remember. .

Y It sometimes helps to set the start time with something other than all zeros. Use distinct hour digits so you can identify it later with a specific tape.

Start recording your MTR or VTR before pressing the Start button on the SMPTE Desk to give it a head start. It¡¯s a safe practice to allow at least 5 seconds of pre-roll before the time code is actually recorded. When you reach the Stop time just click the start button once again.

#### Reading & Synchronizing to SMPTE Time Code

Basically, the procedure to lock your digital audio or MIDI software to another device (MTR or VTR) is as follows:

1. Connect a 1/4¡± phone cable from the audio output of the MTR or VTR (track that contains the time code) to the WaMi Rack 24¡¯s SMPTE INPUT jack.

2. Open SMPTE Desk.

3. Play the MTR or VTR already containing the SMPTE time code, and you should see time code displayed on the Time Code Display Area change. You don¡¯t need to set the frame rate, as WaMi Rack 24 automatically recognizes incoming format.

4. On the MIDI sequencer or audio recording software that you want to synchronize with, set it to chase (or external sync) mode and select SMPTE as type of sync and choose the appropriate frame rate (if necessary). Check the manual of your software for detailed instructions on SMPTE synchronization.

You should off-set the sync start time on your MIDI/audio software so that there is at least 3 seconds of pre-roll for the MTR or VTR to stabilize it¡¯s speed and for the WaMi Rack 24 to correctly identify the time code.

)When the sync is not stable, there will be two possibilities. One is the master SMPTE signal is not clear, in this case you would better to regenerate SMPTE signal. There is another possible reason for unstable sync. WaMi Rack 24 is sensitive to the SMPTE signal level. You need to adjust incoming signal level by tweaking level knob of master sync device from its maximum level. At maximum level, you will probably not be able to see SMPTE IN LED on front panel, decrease the level little by little and if you see the LED lights, that will be the best amount of SMPTE signal level to work with.

## MIDI Connections

WaMi Rack 24 provides 4 in/4 out MIDI interface, enabling you to use 64 MIDI channels. 4 MIDI inputs allow great flexibility in incorporating variety of MIDI controllers. MIDI connections are fairly simple and you probably don¡¯t even need to look at this section. If so, you may want to skip this section entirely.

Each MIDI Input and Output on WaMi Rack 24 will appear as a distinct MIDI In/Out port on your computer, allowing you to access 16 MIDI channels per each MIDI port. Having 4 MIDI Inputs allow you to connect 4 MIDI controller keyboards simultaneously. If you have only one master controller, you may want to connect the remaining 3 MIDI input ports to MIDI sound modules and MIDI equipped effects and devices to store their presets and system exclusive data.

MIDI CHECK

Before you begin using WaMi Rack 24, just check to make sure that you have correctly installed your hardware and software of MIDI part.

MIDI CHECK

< Example– Cakewalk Pro Audio>

If you have followed the instructions correctly and the rest of your computer music system is working properly, you should open your favorite MIDI sequencer and find the following in your sequencer's MIDI selection menu.

<Example – Cubase>

These numbers refer to WaMi Rack 24's MIDI Input and Output sockets. To check if your WaMi Rack 24 is working properly, you should enable all 4 inputs and 4 outputs and see if MIDI signal is present on all sockets.

MIDI IN WaMi Rack 24 Midi In-1 WaMi Rack 24 Midi In-2 WaMi Rack 24 Midi In-3 WaMi Rack 24 Midi In-4 WaMi Rack 24 SMPTE
MIDI OUT WaMi Rack 24 Midi Out-1 WaMi Rack 24 Midi Out-2 WaMi Rack 24 Midi Out-3 WaMi Rack 24 Midi Out-4

1. Open your favorite MIDI sequence and send signal on all 16 MIDI channels to WaMi-Out 1 thru WaMi -Out 4 MIDI Output ports.

2.Check the front panel LED's on WaMi Rack 24 to see if they are blinking when MIDI signal is present. If so, WaMi Rack 24 MIDI Outputs are working properly.

3. To check if MIDI Inputs are working, connect your favorite keyboard controller any one of the four WaMi Rack 24's MIDI Inputs.

4. Set up your keyboard to send MIDI signal on all 16 MIDI channels (OMNI mode) and start playing. If the WaMi Rack 24's front panel LED's are blinking with a press of the keyboard, MIDI Inputs are working properly.

Record music on your sequencer and play it back.

With most digital audio applications, you will find WaMi Rack 24¡¯s In 1,2, In 3,4 and Out1,2, Out 3,4, Out 5,6, Out 7,8 Devices once it has been installed properly. It¡¯s just a matter of selecting the sample rate and the bit depth of your preference from thereon. We have included a few applications below just as a quick setup guide. You should refer to the specific application¡¯s manual on how to optimize the audio recording and playback capabilities. If you have problems or questions with setting up WaMi Rack 24 on your application please contact our technical support.

Cakewalk 9.0

After properly installing WaMi Rack 24 and running Cakewalk for the first time, Cakewalk will recognize WaMi Rack 24 and initiate the Wave Profiler. If not, select Tools/Audio Options from the Cakewalk menu bar to open Cakewalk DirectShow Audio dialog box as below. Run Wave Profiler and it will automatically enter correct DMA settings for WaMi Rack 24.

In this example, notice the default sampling rate and bit depth. You may change the settings to your preference, but if you choose to record at 48kHz and 24-bits, make sure you set the Wave Driver Bits per Sample to 24 as well. Higher bit-depth and resolution consume more disk space, we recommend you to decide proper sampling rate and bit depth according to the capability of your system and necessity. Refer to Cakewalk¡¯s manual for more detailed instructions.

Cubase VST 3.7 (ASIO v2.0)

With a dedicated ASIO2.0 driver, you benefit most from the advanced technology of WaMi Rack 24. After you have properly installed WaMi Rack 24 and run Cubase VST for the first time, select Audio/System from the Cubase VST main menu bar to open the Audio System Setup dialog box as below.

There¡¯s no need to check for buffer sizes or run simulations anymore because you simply don¡¯t have to use Windows ASIO Multimedia driver anymore!

On the top right hand corner of the Audio System Setup dialog box, click ASIO Device and you will notice ASIO 2.0 – WaMi Rack 24 along with other possible drivers. Just select ASIO 2.0 – WaMi Rack 24, and that¡¯s it!

If you have used Cubase VST before with another audio card, you may have had CPU performance problems, especially if you use lots of FX and EQ. With WaMi Rack 24, you will notice significant reduction in CPU usage. Open Audio/Performance from the main menu, and see the difference.

Remember when you adjust to shorter latency, it will give more stress to your system. When you adjust the latency, capability of your computer system must be considered. Better and faster system can support shorter latency.

Logic (EASI)

WaMi Rack 24 supports EASI driver for Logic software.

After you have properly installed WaMi Rack 24 and run Logic for the first time, select Preferences from the Logic menu bar.

In Audio Driver section, check the box on upper left ¡° PC AV¡±, then select EASI- WaMi Rack 24 for the driver.

Power pack set up

WaMi Rack 24 Power Pack includes couple of world-renowned software. Gigasampler and Samplitude Project v5.5 are they.

Samplitude Project v5.5 is a digital audio recording/editing software. 8 stereo tracks are provided with 24-bit and up to 192kHz resolution. Internal 32-bit float-processing is available. Destructive effects, like graphic/parametric EQ, Dynamic section, Time strtching/Pitchshifting etc.. are supported.

Samplitude Project v5.5

When you run Samplitude Project v5.5 first time, you need to set the I/O device with WaMi Rack 24.

Click ¡°?¡± icon at far left side of track info section, and you will see ¡°Track Info¡± window open.

Select ¡°Wami Rack 24 I/O¡± for Playback/Recording audio devices.

If you click ¡°Multi Card Mode¡± button, you can assign different I/O devices for each track.

GIGASAMPLER1.6 LE 8ch(GSI/F)

Gigasampler LE 8channel version is made for WaMi Rack 24 only, and you can get this version with WaMi Rack 24 Power Pack.

If you only want to use Gigasampler with WaMi Rack 24, you can assign all the output for Gigasampler as below.

After you have properly installed WaMi Rack 24 and run Gigasampler for the first time, open Configuration box.

In Outputs section, you need to select WaMi Rack 24 – Gigasampler IF and check the output port that you want to use from Outputs Enabled box.

To use Gigasampler, you also need to check if ¡°GSI/F¡± is enabled from the pop-up menu by right clicking of the mouse button.

Gigasampler and applications

WaMi Rack 24 allows you to use more than one application at once. For example, when you are using Gigasampler, you can run one of your recording/sequencing software to record output of Gigasampler.

However, you should follow steps described below to utilize this function properly.

1. Run Gigasampler and assign output device as directed in Gigasampler set up section. However, you shouldn¡¯t assign all of WaMi Rack 24¡¯s output to Gigasampler, because you will need outputs for your recording application. When you assign them, they should be 1,2 &3,4 or 5,6 and 7,8. WaMi Rack 24¡¯s outputs are grouped in to two sections. Let¡¯s say you want to use only stereo output for Gigasampler, so you assigned output 1,2 for Gigasampler., still you can¡¯t use output 3,4 for recording software because they are related to output1,2.

Again, you have to choose output 1,2 & 3,4 or 5,6 &7,8.

2. Open your recording application only within the Gigasampler. To make this possible, you have to assign ¡°your sequencer¡± from the Configure>Preferences window in Gigasampler. Then, click ¡°SEQ¡± button to open the recording/sequencing application.

3. Select desired output device for the application. They should be other group of output those are not selected by the Gigasampler. If you selected output 1,2 &3,4 for Gigasampler, you should choose 5,6 &7,8 for your application or vice versa.
