Hello
I want to sync my Emx 1 with both Roland tb-3 and Volca Sample (my sample is synced with volca modular) But I need Help with the midi sync ? the out midi from electribe goes to the tb3 midi in and its fine but the volca cant sync when I connect it in midi thru frolm emx ... I tried also from tb3 out to the volca midi but still volcas remains no synced..
