I’m using BeatHawk as a sequencer in Audiobus. My controller keyboard is routed into Beathawk where I have blank pads sending midi notes (each pad is a different midi channel). This app lets me split the midi channels in AB and send to different synths. Thank you. ### 1/5 — Good idea but *2018-09-24* Iinput selection quick and simple. Output channel selection made complicated by a keypad?. This should be done in the same way as the input, just tap the channel box for output. Key pad adds too many actions for such a simple task especially for live switching, pretty useless. ### 1/5 — No Comprehensible Change Log *2018-06-16* Developer has capitulated to the scourge of the GDPR.
