Running time factor and pitch factor. I turned pd lock on and then off in both TF and PF but now it seems that I can't change expression pedal settings in TF or PF. It's permanently locked. I've tried expression pedal over midi and plugged straight in, nothing. I've tried all the obvious stuff, i.e. repowering etc. and nothing. HELP! All of the previous programs that were using expression pedals are working fine but I can't program any new ones?
