[chuck-users] Routing SndBuf (Skot)

[Perry Cook]

I don’t remember SndBuf ever being multichannel.  In fact, there is a SndBuf2 just for stereo.  That UG can be chucked to dac for auto stereo, or allows access to .chan(#) for arbitrary routing.  SndBuf mixes everything down to mono, and I fear there is no support for > 2 channels via SndBuf.

If my statements above are true, then Someone could do us all a cool favor by making a SndBufN chug.
