I think I got it (sort of..) I moved the output from my Ketron from "headphones" to "left" (arbitrarily.) I have no clue as to why that might make a difference, but I would rather have a random inexplicable resolution than several days of intriguing potential solutions which, although intellectually stimulating, still don't fix the problem.

I'm sure it has something to do with stereo vs. mono voices etc. but since I use the Ketron pretty much exclusively for monophonic purposes (and use Real Tracks for everything else) I guess I'm OK.

Thanks, Peter
