yes, absolutely! or 6 channel, or eight...

I have a simple Win32 console program which will do this (4-ch to two stereo),
if it is of any use. Maybe there is already something in the Csound utils which
can do it?

Commercial:
I am looking to provide a useful if preliminary level of 4-channel support into
CDP, for the next release - 4-ch playback (mixed to stereo if needbe), and
4-channel waveform viewer/editor. Possibly also a 4-channel reverberator, once
the Analog card can play it. The time hase come to assert that four channels
can no longer be regarded as 'non-standard' !
