How do I get the KS37 to ignore start/stop signals sent from the Boss rc505 it is slaved to please? As it is, if I have an arp going, it stops when the start signal is sent, and if I start playing on the beat where the start signal is sent, the the KS37 is not in arp mode - I have to wait a beat for it to start working. Seems very weird, and I just want to choose when to start/stop the ks37 myself.
