Well you are in luck !!!
Set Safe Edit (System Setup, Page 2, #5) to ON. If you then try to change patches with the BIG KNOB the HS will prompt you with the message “Discard Change ? – Yes – No” You then select with the two buttons directly below the screen, which light up brightly.
External program change is not affected. If the only change is the Macro that won’t prompt on program change either, for obvious reasons.
Good that’s your only complaint. Now you’ve got a synth which you consider perfect. Good deal !!!
