Thanks for the info, Stephen.

I guess I'll need to look forward to Android L then.

All my devices have stereo output jacks only (no HDMI).

More to the point, though some of my devices have USB connectivity both in 
and out, the only available USB driver (which works with quad), 
USBAudioRecorderPRO, is only compatible with a few *other* devices and only 
with certain apps - of which Csound is *not* one.

I very much hope that with the advent of Android L, the Csound Android app 
will be made to allow for quad output (through USB), if it doesn't already 
do so.
