ARC is a MIDI translation for the Akai APC40 mkII.

By default the APC40 give the user access to the MIDI channels One to Eight. This can be more than enough in most scenarios and in most applications that support MIDI but what if you could have more?

Using ARC with an APC40 mkII you can utilise all sixteen MIDI channels and remap your chosen application as you want to, not as the hardware dictates. 

There are a few caveats with this change. The APC40 will act differently than expected with some DAW’s. Take Ableton for example, the APC (Ableton Performance Controller) was designed specifically with Live in mind and as such, this remapping is partly expected to break things. 

Then why do this?

ARC was created to get more out of Resolume / MadMapper and a few other applications I use regularly. I liked the forty clip triggers but i needed more. Early versions of this patch only doubled the channels and tried to focus on a method of navigation around the newly created channel (ergo ‘decks’). A later version added a ‘shift’ key and took it up to four channels. Struggling with a method to keep track of which channel I was on I redesigned the whole project to encompass all available sixteen and began work on a Resolume usable prototype.

As you can see from the above image, the Resolume install has 16 columns and five layers. Four channels were used to MIDI map every one of the 80 clips and the 80 clip previews. Channel 1 and 2 were used for the clip triggering and channels 9 and 10 were used for the clip previews. ‘Shifting’ between them is a simple case of using the [SHIFT] button (as a momentary shift) or the [BANK] button as a toggle.
