Hi vMixers,

I'm developing a simple "Activators" program for the Akai MIDI controller models APC mini and MIDI Mix.

It currently has very simple features, but it's the plan to extend the program soon.

Features in current version:
- See list of current bindings
- Delete binding
- Add a binding - Bind a input (vMix input) to a MIDI button on a given controller
- Open preset
- Save preset
- Configure which url to use to connect to the vMix webcontroller

Upcoming features
Flashing buttons
APC Mini allows blinking/flashing a button, and it's my plan to enable bindings to include a setting to choose whether the button must flash.

Mapping of buttons
The mapping of the buttons is dependent on the MIDI controller model. I've attached images to the ZIP, showing the mapping for APC Mini and MIDI Mix.

How it works:
First, make sure that vMix is running and the webcontroller is enabled, and the Akai MIDI controller is connected to your PC.
Run the program.
The list of bindings will then be shown in the main window, and it is possible to add and delete bindings on the go.

Adding a binding
First step is to choose which MIDI device you will be using.
Enter the button number and select which input you want to bind to.
The midi button/pitch must be the number wanted corresponding to the button on the sheet of button numbers.
Finally click add, and the binding will be added.

Colors lighting up
APC Mini lights green if the input is in program, and yellow if in preview.
MIDI Mix only allows each button to light up one color, and therefore, it will only light up if in program.

Demo
A demo will follow soon - stay tuned.

Download
The current version is attached to this post.
Simply download and unzip the program. The Midi.dll file stay placed in the same folder as this program.

Changelog
0.1.1 (02/09/2016) - Fixed bug on faulty names of available devices
0.1.2 (04/09/2016) - Fixed bug leading the program to crash
0.2.1 (09/10/2016) - Added save/open preset feature + opportunity to change webcontroller url
0.2.2 (09/10/2016) - Fixed bug when loading preset

The button number is a simple integer, and can be found at the images attached to the Zip. Each button has a unique number. For instance on the MIDI Mix, the first button has number 1, the next has number 3, and so on.

The input name must be corresponding to the input name in vMix. I hope this could help.

Have you tried to change the input from program to preview, and back again on program?
It currently only can recognise state changes when the program/preview in vMix changes, so therefore, you must change which input is in preview/program for it to light up.

And the Midi.dll must stay in the same directory as this program.

Hope this helps.

all the lights light up and off when I first select APC mini from your application.

Yeah not sure.
Plus ran as administrator and check program permissions etc
Windows 10 (before august anniversary update, this should not effect it as system very stable)
Latest Vmix version installed. Lights work fine in Ableton Live.

Cool will check out later or over weekend. Thanks

Woops - forgot to upload the correct executable :-) The v0.1.1 is now updated, and should work, try downloading it again :-)

Yeah, as it is right now, just green for active, and orange for preview (like in vMix), but it's my plan to extend the functionality, also including saving the bindings as a preset.

Will continue working on the program next week.

The program is now updated to v0.1.2, hopefully without any random crashes from now on! :-)

The program ran without crashing on my laptop.
