It hasn't locked up on me or any other such wierdness. I've only had the SC-88 a few months, but I'd miss it sorely if I lost it. If I had the extra bucks, I'd probably get the SC-8850, or the like.
SysEx messages are very complex.
Built in effects are easy to use. It supports GS and GM level 1. 5 Sounds are general purpose. Some instrumentals are not real. Onboard effects are good.
