SubjectRe: Multichannel outs
Hmm, well, I have just downloaded the sekd demo of Samplitue Studio 4.51, and
attempted to load one of my 4-channel files. It does manage, sort of - but the
display shows rubbish, and any attempt to play crashes the program immediately
(and I do have two soundcards in my machine). So, sorry, 'nul points' for sekd
there.

At the risk of repeating myself, I KNOW there are lots of 'multi-channel' cards
available, and that applications which know about them can create a
mutli-channel project, and play it, but NONE OF THEM, to my knowledge, will read
a four-channel WAVE file properly. The better applications reject the file,
informing you of an unsupported format; the not so good ones assume the file is
stereo, if it is not mono, load it, and then throw wobblies. 

Everyone on this list who has a recent verison of Csound (certainly on the PC),
can use it to create a four-channel WAV file. Can I suggest a global research
project to find all the applications, and soundcards, which will read and play
it?

Failing that, with John Fitch's agreement, I could provide example multi-channel
WAVE and AIFF files (let us say, 4,6,8,16 channels) on the Bath site, for anyone
to download and use to test products with.
