## 3. Driver Update

- Unzip the driver update package ("tpro-win64-107.zip") with the included subdirectory structure to any folder.
- Uninstall the driver software like described in "Driver Uninstall".
- Restart Windows

### 3.1 Windows XP/2003

- Logon with administrator privileges again.
- Now, the Windows Hardware Wizard starts with a "New hardware found" dialog.
- Do NOT use the option "Install software automatically". Use the option "Install from list a specified location"

- After the driver installation a restart could be necessary.
- After these steps it might be necessary to update the firmware of the Trace Pro. It can only be determined after the installation of the new driver if a firmware update is needed. If that is the case, the update will then be performed automatically. In order to get the new firmware in effect, you have to SWITCH OFF and to SWITCH ON the computer.
- Subsequently to a successful firmware update, Microsoft Windows™ XP/2003 will find a new hardware after reboot, since the hardware ID of the Trace Pro will have changed due to the firmware update. Since the driver files have already been installed, you only need to choose “install software automatically” in the appearing windows hardware wizard.

### 3.2 Windows Vista/2008

- After the restart the message "Found new hardware" appears. Click on "Locate and install driver software (recommended)".

## 5. What's new

### Version 1.07:

- First public release based on the version 2.36 of the 32-bit Windows driver

## 6. Operation in Windows™ Vista / Windows 7

On Windows™ Vista / Windows 7 audio applications, who do not use ASIO or WSAPI, are not able to set a certain samplerate or sample format. Instead, sample rate and sample format is set in the advanced settings of an audio device in the windows control panel. This leads to the following:

- If the desired samplerate of an audio application is not equal to the current set samplerate, a samplerate conversion with possibly an audible loss of quality will be the result!
- When using an audio device of the sound system with the samplreate x and additionally attempting to use another device but with a samplerate y, an error message will appear, since the soundcard may only be used with one samplerate at a time. Unlike Windows XP, Windows Vista/7 undertakes no sample rate conversion in this case!
- In order to operate several devices with a certain samplerate, this samplerate has to be set up in the advanced settings of an audio device in the windows control panel for each device separately. As concluded from the previous point – no device of the soundsystem should be in use, or else a change will be rejected!
- If you want to set the sample format for the audio devices, first start with the playback devices and afterwards with the recording devices. Background: When you open the tab "Recording", Vista/7 starts a recording with each recording device in the list to be able to show the input levels. In this case your MARIAN Audio System is in use with a certain sample rate! If you now change back to the tab "Playback", Vista/7 wil not stop the recording and a change to different sample rate for a playback device will fail.

## 7. MME, WDM-Audio and DirectSound

Audio applications, who do not use ASIO or direct WDM-Audio, now communicate with Microsoft MME or Microsoft WDM Audio drivers instead of communicate with the MARIAN drivers directly. The Microsoft drivers in turn communicate with the MARIAN drivers.
For audio applications, who use these Microsoft drivers, apply:

- They can playback simultaneously using one playback device. The Microsoft Kernel Mixer mixes the playback signals of the applications into one stereo stream and routes it to one physical output device. If playback takes place with different samplerate, the Microsoft Kernel Mixer converts the samplerate of the playback streams to the highest samperate required.
  Hint: You can improve the quality of this conversion! (See Control Panel | Sounds and Audio Devices | Audio | Sound Playback | Advanced | System Performance)
- The described simultaneous playback of different applications fails, if the output device is already in use by ASIO or direct WDM-Audio.
- The number of the available recording and playback devices is limited. With Windows XP/Vista/7 to 32 devices each (64 channels)
  This limitation applies to the number of all audio devices installed in the system.
  You can use ASIO to walk around this limitation.
- The minimum possible latency is limited to app. 20..30ms through the Microsoft Kernel Mixer architecture.
  Use ASIO to walk around this limitation.
- Some audio applications show additional audio devices with theirs names appended by "(3+4)" or "(5+6)". This is caused by an anomaly of the Microsoft MME/DirectSound system. Please ignore these devices and do not use them.
