Hello! I don’t think that this is a fairly common thing, as far as I know it’s only done with the Axe Fx, Kemper, and TC Electronic G Major:
Currently using Mod Duo X. Wondering if it would be possible (or what it would take) to send Audio Tuner Info/Data as Sysex (din out or USB out) to send to a midi controller like the RJM Mastermind?
That would allow for Tuner read out on a midi controller.
