extraits :
1) Faq :
"ASIO4ALL requires exclusive access to the audio device. More often than not, starting the driver fails because the audio device is already in use. There are obvious instances, like some other audio application still open, but there are also things to consider that are not so obvious. Such as the "Microsoft GS Software Wavetable Synth", which is enabled as a default MIDI output in some sequencer software. Check the MIDI settings of your host application!"
2) History :
"Add a Message Box whenever it has been found that the audio device is already in use. In nine out of ten cases this is because the 'Microsoft GS Wavetable SW Synth' is enabled as a MIDI output device somewhere. "
