I have just bought a Bitbox from Sweetwater. I am trying to trigger samples with MIDI with no success. I have tried using Beatstep Pro, QuNexus and QuNeo and the Bitbox does not respond to any of them. I verified the QuNeo grid pads are sending out drum nots on channel 10 notes 48 and 49 with a custom configuration and I am using the adaptors that came with my Beatstep Pro. It seems like there may be something wrong with my Bitbox.
