The H9000 only receives MIDI notes via MIDI DIN, USB-B, or USB-A

These algorithms make use of MIDI note data: https://cdn.eventideaudio.com/manuals/h9000/2.0/content/appendix/algorithms/24_MIDI_Keyboard.html

I expanded one of them a while ago: https://github.com/jbaylies/sousastep-h9000-presets/blob/main/custom%20algorithms/Midi%20Harmony%208.sig2

If you use a DAW to map MIDI CC to the Emote plugin’s Functions, the Function data will be sent from Emote to the H9000 via the Local Area Network.

If you use Emote to map MIDI CC to Functions within Emote, that MIDI CC data can be received via MIDI DIN, USB-B, or USB-A.
