Maybe simple IS good...

The point I was trying to make about sustain is, I prefer independent sustains for UPR and LWR, to better choose which I am sustaining at any one time. In other words... TWO sustain pedals. Sometimes you need to hold the upper sound, sometimes the lower. One pedal makes it an all or nothing situation.

Did you ever even TRY to program the Emu to get to the 'hidden' G70 parameters?
