Boss DR-202 Backlight & Sync Pulse

#dr202 now outputs a sync pulse compatible with #pocketoperator#volca and my recent looper sync mod. new backlight beatcounter defaults to the kind of orange you expect in 1998, but slowly color drifts when stopped. but how? #digispark used to sense the voltage change when the light behind the play button blinks.
