7. 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:

7. MME, WDM-Audio and DirectSound

Audio applications, who do not use ASIO, GSIF or direct WDM-Audio, now communicate with Microsoft MME or Microsoft DirectSound 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:

8. Software Sampler and Synthesizers

Software samplers and synthesizers normally supply MIDI output devices for other audio applications who want to use the software sampler as an instrument. If such an application starts, then normally this application opens the MIDI output devices and this in turn causes the software sampler to initialize its audio engine with the configured audio outputs.

In the described situation the software sampler and the other audio application may conflict, if they use the same audio output. You can use the Trace D4 with different audio applications at the same time but never the same output device simultaneously.


Therefore this hint:

The Windows Multimedia System also supplies a software synthesizer called  "Microsoft GS Wavetable SW Synth". This synthesizer has also a MIDI output port with the same name. Since there is no explicit setup for the output device, the "Microsoft GS Wavetable SW Synth" always uses the standard playback device configured in "Control Panel | Sounds and Multimedia | Audio".
