I’m a big proponent of Event Processors as they can make just about any MIDI message into anything else, or use incoming Events to create more complex scenes or series of events.
If you decide to break your philosophy of eschewing extra equipment, you might find including one as a serious advantage towards achieving your goal seamlessly.
As an example, it would be interesting to Send from your controller Note Events and then translate those to the CCs needed to control Track Mute States or even Sequences.
It’s a shame that iConnectivity won’t allow this type of 1:1 translation - it would seem to be easy.
Edit to add: I checked the iConnectivity website for info on their Auracle system to see if it’s possible with their routing/filtering abilities but it seems they dont’ actually have manuals - only videos. I don’t do videos.
But one thought would be if you could send a Note Event on a specific channel and have iConnectivity perhaps translate the Note# to a value for CC69. So as an example, you’d send perhaps a Note 7 and the router would convert that to a CC69 value 7 message - which with PyraMIDI would launch SEQ 7.
Note: That’s SUPER simple with a BomeBox, but I’m sure that’s more investment (time, energy, and instruction) than most would prefer. Understandable. MIDIHub might be able to do this, or perhaps the MIDI Solutions Event Processor - I don’t know for a fact, but at least the former has some extra nifty features that you might find valuable.
