Hi there,
I use a digitakt midi out to o Coast and USB midi out to iPad with DRC or Model 15. O Coast is on Midi CH 1 iPad on Midi CH 2. If I record the Midi for Chanel 02 (MIDI B) it also plays my O Coast on Midi Chanel 1 (MidiB). I checkt midi learn on both machines, checked the Digitakt for recieving USB Midi in/out. Cant find the problem. Can somebody help me? Regards, Veith
0-coast MIDI is probably set to OMNI. If this is the case, try to set it to listen channel 1 only.
If tried this : https://www.youtube.com/watch?v=uTvmj5f3AD0 several times. Somehow it doesn’t work 
It actually plays now but it doesn’t record.
Somehow it worked now. Did the same several times. Thx, Veith
