How many times I need change the keytouch to medium? I can not find how to do it one time as a permanent settings. Changing anything (style, program etc.) return to Roland "hard" preset.

The same with all other settings. How many buttons I should to push to set modest reverb to all styles and voices?

Only useful settings that I can change one time -- equalizer. Others need resetting per style/program button. Several days of pushin buttons...
