Hello,

I've found some cool information on my midi device.

https://d2r1vs3d9006ap.c...mini_midi.jpg?1421447412

Shows all the codes and how to turn the lights on/off.

eg: 90 00 00 turns button 0 off 90 00 01 turns it to green.

I guess what I'm asking for is a way to link that back from VMix. So right now you can control VMix via midi, but when you mute input 1. It would be REALLY nice if Vmix could send feedback to the midi device.

So when you are programming an action, you can return a status as well.

So on input 1 mute send midi code xx xx xx. It would take the midi support to the next level.

Input 1 in Program send midi code yy yy yy and so on. Essentially the opposite of how assigning the midi keys work. Where you assign midi codes to actions/events in Vmix.

Watch out: Someone could end up using VMix to drive one of that Crazy XMAS displays that is synchronized to music and a giant video wall next. (I'd just be happy with controlling lights on the APC Mini).

Keep in mind there could be a few different possibilities like 3 colours and the ability to Blink. I imagine all the other AKAI controllers work in much the same way.

I noticed the lights were working on the Akai controller they used for the October live stream. Any help on how to do this guys?

I too want this feature, if possible.
I got a KORG nanoKONTROL2 for our audio mixing and showing stuff like mute and solo indicators would really help.

Plus 1! I have a Behringer Xtouch mini, and works very well with vmix. But actually I can't activate the lamps... It can be a very good feedback for the operator.

I have a script in the 3rd party dev thread that shows how to do MIDI feedback yourself that is worth a look, includes code for the Akai APC 40 MK1. But I also would like to see this rolled into vMix

This can be adapted for any MIDI device.

I think the hard part here is getting midi feedback that is any sort of usefulness will need to involve some sort of user scripting and they developed the API with no feedback abilities whatsoever, a point that I touched upon in a previous topic when trying to fetch information on current live input and being forced to parse the XML document to do so. The class objects for inputs only contains abstract methods to run functions, no "feedback" of any sort.

For example I can set an input by Input.Find("MyInput") but in a standard object oriented environment I should also be able to GET the current input via Input.Active.Name, this would all flow into a built in midi class pretty easily by subscribing to an event in the Input class and calling the midi feedback methods.

The alternative would be vMix to have hard coded logic and options which could cripple its usefulness much like the abstract methods and "function" methodology cripples the API.

Dunno, just thinking "out loud".

Correct, at preset you must use 3rd party tools to enable feedback or midi return.

Are you able to compile code for the APC Mini?

The mini isn't documented very well, The best I have found is this:


But since I dont own the mini I have no way to know its accuracy, but I have the code posted in the other thread, feel free to tinker.

+1. Clearly a lot of interest for having such a feature, since the AKAI APC40 MKII and the Numark Orbit are used by so many Users, including the vMix team. Not to mention all the other Midi Control Surfaces. A simple scripting function such as : API.Function(“MidiDataTX”,,StatusByte,,DataByte1,,DataByte2)

StatusBtye = The Note ON/OFF & the Midi Channel
DataByte1 = The Note Number (1-127)
DataByte2 = The Velocity Value (1-127)

It certainly would bring life into all those control surfaces. All those LEDs awaiting the commands.
