MIDI Ioopback

Early alchemical ouroboros illustration with the words ἓν τὸ πᾶν ("The All is One") from the work of Cleopatra the Alchemist in MS Marciana gr. Z. 299. (10th century)

Anyone doing MIDI loopback, ie. a technique of setting a device to send MIDI to itself?

I’m new to the game, bought my first ever actual MIDI cable today, and am learning how Digitone does loopback. From what i understand MIDI targets which cannot be addressed with the usual LFOs can be controlled this way.

I have no idea how i figured it out, but apparently a roundabout way around NRPN which recycles MIDI cc numbers is to communicate on different channels, eg. MIDI cc 72 normally on filter envelope sustain is delay_{delay_{delay_{delay}}} lowpass filter on channel 9.

It seems I can also send MIDI and modulation between the MIDI channels, e.g.


MIDI feedback?
