I believe I hit the out-of-note-polyphony issue with my SC-55 with the TIE Fighter Collector's Edition intro tune. There's a part with four (I think) rapid string runs in quick succession; my Yamaha MU80 and the Sound Canvas VA play all the string run notes, they're all clearly audible, but the SC-55 only the first few per run and the rest are completely missing.
I wasn't sure about the root cause, but I think the lower of polyphony of the SC-55 (v1.21) sounds like a plausible explanation.
Actually, I've done a recording of the MIDI, so I'll to try play only the string channel in solo. If this theory is correct, then all notes should play out with the channel soloed.
Confirmed, my first revision SC-55 can't handle the note polyphony requirements of the TIE Fighter intro music in a few places. Apparently, that soundtrack was composed on the SC-55mkII. When I mute a few MIDI channels in the problematic section, all missing notes start playing.
