ok, that works. it just seems counter-intuitive that chcopy is a mix operation with a default of averaging a signal and null, in this sort of situation. however, i guess if one was chcopying a number of channels to one destination channel, that would be necessary.

thanks for the help -- i've learned a little more about how ecasound's (or kai's) brain works!
