I have no doubt that vMix will at some point support MIDI out to allow us to use our indicators on our MIDI devices as a tally board, but in the meantime this workaround is tested and works wonderfully. The code will work out of the boc for the APC40, other devices will need to modify their channels and notes. This will dynamically light up clips on your board as shots are added to vMix, it will also re-order lights if tracks are re-ordered in vMix. Active overlays will also show as live. Uses the midi-dot-net project from https://code.google.com/p/midi-dot-net/ to simplify the MIDI out process. Code:using System;

There are no setting, no nothing really, just quick and dirty code. jhebbel attached the following image(s):  20151028_193834.jpg (2,546kb) downloaded 133 time(s).You cannot view/download attachments. Try to login or register.
