The 'View->Buses..." menu allows configuration of multiple channels of
audio beyond two. I just configured a 12 channel track, for example.
There is a bug related to this issue, and it may indicate that it has
been tested more with stereo output and non-multichannel cards. The
gui itself permits configuration of up to 99 channels.

You can get it to change the number of channels, but it may crash
jackd in the process. Requiring a qtractor restart after you save the
file/template with the multichannel audio bus. This is a known bug:
http://sourceforge.net/tracker/?func=detail&atid=733076&aid=3021645&group_id=135501
that is still present in subversion.

After jackd crashed, I was able to save the qtractor template with a
12-channel audio template and it correctly setup that 12 channel
template next time I restarted qjackctl and restarted qtractor.
Qjackctl indicated 12 audio inputs (Master/in_*) and outputs
(Master/out_*) available in qtractor, in addition to the 2 channels of
monitor (Player/out_*). The mixer shows 12-channel metering, etc.
Clearly there is support for multichannel audio.

 The bug only seems to be invoked on bus creation with multichannel
sound cards. And not stereo cards.

I don't think it's fair to compare a bug in an "alpha" (<0.5)
opensource software package with a many-years-old project nearing
3.0... But yes, ardour is very comprehensive -- and totally confusing
and overwhelming to the novice.

Makes sense. No point in duplicating effort.
