For so long, I contemplated the 5, having gigged at least 15 straight years with Korg (800/3X/4X). I decided to give the 920 a shot. I have to say, this is one terrific board. OMG. I am absolutely blown away how you can 'ebb and tide' your performance, meaning, rock, disco, soul, funk to absolutely elegant soft stuff, with feeling! It is a bit daunting live, but not too bad if things are set up in advance.
