Jande Appreciate the feedback. I use midi mostly as a check on music that I'm putting into scores, so I'm not really needing "musical quality." Just accuracy of the note detection. It sounds like your experience indicates I might get some good out of it. Other things I've tried were a long way away from useful. The other possibility is that James just whistles in key better than I can play. :-0 It will probably be a while before I get around to trying it out - too many other things broke and need fixin'.
