Hi guys ! I'm just wondering why there's a little trim-pot in the HR-2's PCB... I've opened it some days ago and saw it, so I was thinking to change the position, but if it's a fine tune of the pitch accuracy, maybe I can't find the original position and have a bad experience messing with it... BTW is there a way to connect an Exp. pedal on it ? Just like the PS-3 and PS-5. Somethig like make an extra hole for a jack ??
Leave the trim pot alone until you really know what happens!!!! There is no way connecting a expression pedal, the other jack is for direct trigging to get a clearer/cleaner signal hitting HR-2.
