My initial quick test indicates that you would likely have some problems sending timely resets to the ER-101 from this setup. For some reason, I thought in the past I’d been able to connect my iPad directly to the SC using the camera connection kit but I couldn’t get that to work for me. So I had to go through a Focusrite iPad dock - doubt that makes any difference but thought I’d mention it.
The yellow signal is clock out of the iPad/Patterning 2. It’s a standard 96 ppqn MIDI clock. The blue line is a unipolar note trigger event. I have one of the Patterning tracks set up to play on every step, set to 1/32nd note intervals.
It looks to me like the note events are coming pretty late in relation to the clock signal. If I have set this up correctly that would be too late for the ER-101 to acknowledge the reset for the clock pulse that it goes with - it only allows 0.5 msec and this is almost 18 msec.
I must admit part of me wonders if I’ve set something up wrong, as that seems like some pretty sloppy timing indeed. I can try some more later but thought I’d put this up in case you or others had thoughts.
