New DirectCsound version provides the opcode "fout" that can output samples to audio file
with any number of channels (now it is limited to 64 channels, but it can be easily
increased). The problem is to find a program that can load and play these file types. Also
more instances of "fout" can be used in order to output several audio files in a single
csound session. For example to handle octophony, it is possible to generate eight mono
wavefile or four stereo file, then it is possible to load them with Cool Edit Pro and send
channel to different audio cards (but I don't know if the synchronization can shift) or to
an audio card of more channels such as the Korg 1212. 


It is easily possible to create two macros containing the output orch lines which can be
renamed when the user choose to use a single multichannel file or several mono files.

At present time realtime is allowed only with mono and stereo output at any sample rate
(with the Sounblaster live it is possible to use any sr from 6000 to 48000 Hz
continuously).
If you are using MME drivers, you must add the flag -+e to enable non-standard sr.
