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;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Windows.Forms;
using Midi;
using System.Threading;
using System.Net;
using System.Text.RegularExpressions;

namespace APC40_Shot_Selector
{
    public partial class Form1 : Form
    {
        List<shotKey> shots;
        Thread shotListThread, shotStatusThread;
        public Form1()
        {
            InitializeComponent();
            ExtensionMethods.outputDevice = OutputDevice.InstalledDevices.FirstOrDefault(d => d.Name == "Akai APC40");
            ExtensionMethods.outputDevice.Open();

            shots = new List<shotKey>();

            shots.Add(new shotKey(1, Channel.Channel1, Pitch.F3));
            shots.Add(new shotKey(2, Channel.Channel2, Pitch.F3));
            shots.Add(new shotKey(3, Channel.Channel3, Pitch.F3));
            shots.Add(new shotKey(4, Channel.Channel4, Pitch.F3));
            shots.Add(new shotKey(5, Channel.Channel5, Pitch.F3));
            shots.Add(new shotKey(6, Channel.Channel6, Pitch.F3));
            shots.Add(new shotKey(7, Channel.Channel7, Pitch.F3));
            shots.Add(new shotKey(8, Channel.Channel8, Pitch.F3));

            shots.Add(new shotKey(9,  Channel.Channel1, Pitch.FSharp3));

}


There are no setting, no nothing really, just quick and dirty code.

@jhebbel,
Do you happen to have code that will work with the APC Mini? If not, I guess I could just buy and APC 40.

Thanks for the post on this!!

You can dump the OutputDevice.InstalledDevices object to find the "name" of the device, then use the graphic below to find the notes and velocities.

Friends, please help me! I'm not a programmer! I directed live broadcasts, the project is now on sports. I need to configure APC 40 MK II that would be under the my tasks button glowed the appropriate color. For example - the top line is the program, where the selected button is lit red. The second line of the preview, there is selected the button is lit green. Bottom line - the credits, there is lit purple. Ideal - if the whole top line of buttons is illuminated with red light, and the selected channel is bright red. Ready to pay your work completely.

I wish I had a MK II so I could help out, but without the device in front of me, its hard to develop for. Surely there must be somebody who has one and has c# experience that can work with the code I posted.

Sweet, im going to get into this next week. Ive been writing a piece of software called inputmapper which has the purpose of connecting and using devices that they weren't specifically designed for.

An example is here of me using a audio spectrum input plugin and the APC 40 output plugin to make a visual spectrium that I demo here:


I intend to make a vMix plugin and with this info I can make a APC 40 MKII plugin as well.

In the example below, the operator presses Pad Number 3 on the APC40 (designated as the Preview Bus with 8 buttons assigned), and the Pad lights-up, and also extinguishes the other 7 Pad LEDS at the same time.

I like this idea! With your image, I thought it was already part of vMix, but after looking for it, I realize you are wanting this capability, and this was likely a mach up of what you desire.

In the OtsAV Midi Mapping Language, they configure lights with special code.

They initialize the LEDs with the following to assign the lights to variables for readability
!blink[~var_name, M,MIDI:off:code,MIDI:on:code]
Example:
!blink[~deck_a_playpause_led,M,0xB0:0x4B:0x27,0xB0:0x4A:0x27]

That is an example for the Denon DN­HD2500 DJ MIDI Hardware Controller deck A play pause button.

Then they call it with something like the following.
BlinkSet(~var_name,x)

The x...
x = 0 (off) (bit: 0000)
x = 1 (on) (bit: 0001)
x = 2 (slow blink) (bit: 0010)
x = 3 (medium blink) (bit: 0011)
x = 4 (fast blink) (bit: 0100)
x .... x = 12 (inverse fast blink) (bit: 1100)

like so...
BlinkSet(deck_a_playpause_led,2)
Causing a slow blink situation.

For the ones looking for a working code, on the Akai APC Mini:

Replace all the lines in the method Form1 from the code from the code initially posted looking like this:

Code:
shots.Add(new shotKey(X, Channel.ChannelX, Pitch.XXX));


With the following code:
Code:
shots = new List<ShotKey>();

// MIDI controller - Button number offsets
int OFFSET_1ST_LINE = 56 - 1;
int OFFSET_2ND_LINE = 48 - 1;
// Bind input (shots) to a button on the MIDI controller
for (int i = 1; i <= 8; i++)
{
   shots.Add(new ShotKey(i, Channel.Channel1, (Pitch)OFFSET_1ST_LINE + i));
}
for (int i = 9; i <= 16; i++)
{
   shots.Add(new ShotKey(i, Channel.Channel1, (Pitch)OFFSET_2ND_LINE + i));
}



This works for visual feedback of the first 16 inputs vMix, on the two upper rows of buttons on the APC Mini.


EDIT: And remember to change the device name to search for, to APC MINI.

Hi ichn1, I'm currently working on a enhanced program that enables both Akai APC Mini and Akai MIDI Mix in use.

I'm expected the program to be released tonight, or perhaps tomorrow. Hope the waiting will meet the expectations.
