Dave, how about that infamously well known "effects phase cancellation" phenomonem that occurs when Yamaha stereo sampled voices are mixed down to one mono Bose Compact unit, of which I've found sounds thin, harsh and unsatisfactory. Imho, going out stereo to two discrete Bose units is pretty much neccesary to preserve the full and rich sound, especially with Yamaha arrnagers.

Also, because I realize how much you enjoy playing LH bass lines, while trriggering auto accomp chord recognition with your RH, I'm curious how you're going tolerate not being able to do this on the S910, or on anyother Yamaha arranger model for that matters.
