This is a MIDI panic rack.
I’ve been using Drambo more and more to sequence external devices, and sometimes you get a stuck note. Especially after today’s AU host update, I thought this might be useful to folks.
This MIDI rack rapidly sends a MIDI On/MIDI Off combo (both with Velocity of 0) for MIDI notes 0-127. It also sends the standard MIDI CC 120 and 123.
There’s an embedded MIDI pass-through mixer, so you can route your usual MIDI chain through this without losing anything.
