I setup & Midi the unit with my E60 KB no prob.....I set the FX reverb to my needs eg: hall......all works great.....

Then I'll play a few chords and stop and for some unknown reason I lose the reverb that I setup.....if I just turn the FX knob a little it returns ....but the same thing happens over & over again I need it to stay with the reverb I set up......any clues?
