Yes, Joachim. I think this is precisely what Victor was suggesting, and I 
plan to implement your joint plan. Thanks so much.

Since this presents the option of simultaneous mono and stereo input files 
being combined, here's another issue:
in order to "balance" mono and stereo inputs, would it be more appropriate 
to output (from a mono file) this:
outs a1, a1
or this:
outs a1*.7, a1*.7
?

My cue for the latter comes from pan, where you distribute a mono signal in 
stereo space with approximately equal power - the "centerpoint" being the 
(approximate) multiple .7 when compared to hard left or right.

i'm glad it's working for you, art. i am not sure if i understand you  
correctly, but i think there should be no attenuation of the signal  
here. but this may depend on your input sources, and testing and  
hearing may be the best. as always ...
