Try these steps. I just tried them exactly as is and they work:
1) create a knob in MIDI Designer
2) set its channel and CC to 1-28
3) go to Sunrizer and tap Learn
4) in sunrizer, tap on "color" so that it turns blue.
5) go back to MIDI Designer and turn the knob.
6) go back to Sunrizer and the color knob should say "28" instead of saying "--"
7) shut off Learn mode
8) go back to MIDI Designer and turn the knob
9) go to Sunrizer and ensure that the knob is in the new position
Note that some of the low cc's (like Modulation) are already mapped to Sunrizer.
Animoog exposes its MIDI ports via MIDI over WiFi. So if the second iPad and the Animoog iPad are on the same network, MIDI Designer will be able to connect to Animoog directly.
- Click on "Network Session 1" on Animoog
- Click on your Animoog iPad's name in MIDI Designer Connections (more -> config -> connections)
- Move a knob in MD, and the "IN" sign will light up green in Animoog
