Hi Bob. Working backwards, if you are going to call them HiFi, then I would do just that. I would make a stereo MP3 at 192 or 256, so no artifacts are heard. With today's download speeds and a short demo, this should not bother anyone.

I had an SD 80, which had the same MIDI engine as your SD 90. The files should sound great.
