In case no-one else has replied:

just use two output args with soundin:

a1,a2    soundin ...

you can even read in four channels, assuming you have some means of
playing them!

(see the manual for more info)

How is people playing quad files?

At the moment I have 2 PowerMacintosh (6100 and 8600) and I am wondering if
they could be chained or synchronised to play two stereo files at the same
time. Maybe there is a way of using Ethernet or Appletalk to keep them
playing at unison.

Or maybe I should promote a bit the business of Digidesign and buy an
Audiomedia III. But, wait a minute, someone said somewhere that
SuperCollider will support the Korg 1212. Now I dont know what to do.


In any case it seems that no version of CSound supports multichannel
playback. Is that right?

Many thanks.

SGIIndy... it has built-in quad. I have use it and works pretty good.

	well, you could setup CSound on both machines, create 2
versions of your orc (front/back speakers) for the same score - run the 2
orcs (might as well take advantage of the "multi-pprocessor" system yoiu
have there) then create a simpleMIDI  playback orc and trigger the
playbacks from a single MIDI controller.  (or use GrainWave or any other
MIDI playback app for that matter)  -- its worth a try -- i'd like to
know how it works out...

(at one point we tried to get the API from digi for accessing ProToolsI
card so CSound-perf could playback in quad - but no luck - although we
didnt try too hard)

you might manage to send out two additional channels through the analog
connections. suggest you check with them.

	I don't think the solution is two machines so much as it
	is two sound cards. It's not too difficult on a pc to set-up
	two sound cards to get four channels (Turtle beach's card have
	been capable of this for some time , provided you have the 
	resources for both cards;) on a Mac, well...I couldn't tell
	you but it seems in principal about the same thing.

	Protools etc. isn't going to help, you could have 16 virtual
	tracks but if your i/o is two channels they are still going
	to have to be mixed to stereo. You need four channels of
	output which probably means two compatible stereo cards
	that can be addressed simultanelously and seperately.

	best,

In danger of stating the obvious, but the Extended Csound card for
Analog Devices has 6 outputs, both digital and analog.  All I need now
is a quad/sextet  amplifier and 4 more speakers

Get an SGI.  I can't remember if the new O2s have four channel output but 
the indigos come standard with four channel output.  A friend of mine at 
Apple said it might be possible to get another card for additional 
outputs, but I have never researched this possibility.  We have been 
using quad sound on our indigo2 for some time now, experimenting with 3-d 
sound and we have been very happy with the results.
