Since I haven't received any response on this, I assume that this is not a trivial task. However, has someone on this group done anything similar before (may be without using DirectX/DirectMusic)? If so, what should I look for? I wandered (literally) through the DirectX documentation on MSDN and elsewhere but could not find any useful information. All I can guess is I have to use DirectSound, IDirectSoundBuffer8, IDrectMusicSynth or some combination of the above. Any pointers will be greatly useful.

My next objective is to export the audio as a WAV file from my sequencer application. I can easily create a MIDI file. But is there an API to access the samples generated by the synthesizer and save them as WAV file (especially since the instruments I am using are from custom DLS)? Thanks again for you help.
