ARC is a MIDI translation for the AKAI APC40 mkII ONLY, and offers you more control over the applications you want to control with it. Created using Bome MIDI Translator, it runs on Windows and Mac as well as the new M1 processor under Rosetta2.
ARC gives you full access to all sixteen MIDI channels via the familiar APC40 control surface.
To offer this expansion, we have utilised three of the existing buttons on the controller. These buttons now cease to operate as standard within the AKAI APC40 mkII ecosystem. If you rely on the [PLAY], [RECORD] or [SESSION] buttons for your day to day use unfortunately ARC may not operate as you expect out of the box.
We offer a trial version of ARC for download, which is limited to twenty (20) minutes of full operation in one session.
In using ARC, you understand that you will have to create your own custom MIDI mapping from scratch for your application of choice. We will endeavour to create and share MIDI mapping files for as many applications as possible as time progresses.
Unfortunately there is currently no method to save your channel setup to a local settings file. Your MIDI mapping data is SAVED to your MIDI mapped software. The UI will require setting up upon the loading of the patch, prior to use even though the MIDI controls will work as anticipated. We are hoping to be able to support local disk writing in the future.

NAVIGATING BY CHANNEL
It is worth pausing here to explore how you switch between channels using ARC on the APC40 mkII.
Upon startup all [CLIP TRIGGER]‘s will be RED and the display will be a solid colour. Below this, the first [TRACK SELECT] button will be illuminated. Pressing any of the remaining [TRACK SELECT] buttons will give you direct access to channels one to eight.
Pressing the [Channel Toggle] button [PLAY] will swap you into the higher channel range of nine to sixteen (9-16). Press it again to return to the lower channels.
When you have moved into the higher channels the [TRACK SELECT] buttons will flash to show you easily which channel range you are currently in.
USER INTERFACE OPERATION
Entering the user interface (UI) of ARC is simplicity in itself. Simply press the [PLAY] button on the top right of the controller and the [CLIP LAUNCH] area will change to the UI mode.
The UI description.
Here you are able to change how ARC behaves and displays it’s channel information. You simply access the UI on each selected channel to set it up.
The first eight of the buttons display the various pre-programmed flashing styles available to you for your selected channel.
The topmost left button will set the channel to a solid colour only.
The remaining buttons will set the channel to it’s denoted flash style.
The middle three rows of the [CLIP LAUNCH] section is the colour palette at your disposal. Simply press the colour you wish to use and that channel has its colour values set. Press and hold the button down to see a solid colour preview of your chosen colour.
CLIP LAUNCH DISPLAY MODES
The three display modes available to you simply offer a different method of viewing the channel you have selected. The three that have been created (at the moment) are detailed below.
Using the topmost [SCENE LAUNCH] button (illuminated in your current channels colour) will set the display to solid colour mode. This sets all the [CLIP LAUNCH] buttons to your chosen colour. Nothing fancy, just a plain block of illumination.
The second from the top [SCENE LAUNCH] button will set the display into mode 2.
This mode displays a palette of colours across the topmost row using red, green, blue, cyan, magenta, yellow, white and orange. This is useful when you want to MIDI map colours onto specific hot keys. The remaining four rows are distinguished by two, four by four grids. This mode has been useful for content triggering within Modul8.
Finally, the middle [SCENE LAUNCH] buttons sets the display into mode 3.
This mode (as above) sets a different display to those before it. Once again the colour palette is available by default however the remaining four rows are setup into four, two by four columns of colour. This mode has been useful from a Resolume perspective for setting up effect bypasses as well as directly accessing grouped clips.
Notes on colour settings.
For the modes that offer multi colour displays, it is worth understanding how the colours are pulled. ARC is simply pulling the colour information (flash type and colour) from the next sequential channel data. On the mode 3 display this is pulling the colour information from the three subsequent channels. So if you want to mix and match your mode 2 and 3 colours simply jump forward to the next channels and set their flash type and colour from there.
LED DISPLAY RINGS
ARC allows you to access all 256 available rotary pots and subsequently choose how the LED rings are displayed on a channel by channel basis for both the [TRACK] and [DEVICE] pots independently. Below is a brief overview of the available settings.
To change the [TRACK] pot LED type use the forth [SCENE LAUNCH] button. Each press will change the colour of the button through red (mode 1), green (mode 2) and blue (mode 3). It will then loop back to mode 1 and red in colour.
To change the [DEVICE] pot LED type simply follow the above information and use the fifth and final [SCENE LAUNCH] button to do so.
The default display mode for the APC40 is a single illuminated line that rolls from left to right.
Pressing and holding the corresponding button will highlight it in [RED].
Display mode 2 sets all LED illumination to that of the ‘volume’ control type. This fills the LED ring from left to right.
Pressing and holding the corresponding button will highlight it in [GREEN].
Finally, display mode 3 sets all LED illumination to the ‘pan’ style of display.
This illuminates from the left up to the centre of the pot and rolls over to the right illuminating the remainder.
Pressing and holding the corresponding button will highlight it in [BLUE].
EXTRA UI FEATURES
Aside from the flash type, colours, display modes and LED illumination you can also change how ARC set the buttons.
The bottom row of the [CLIP LAUNCH] buttons is used to toggle various features on and off. Some of these buttons are currently not illuminated, and will be home to some of the other features that will be implemented into ARC over the coming releases.
A RED button denotes that ARC is in its default mode. Once pressed, it will display the feature you are changing by showing a two letter code:
MI – Set MIDI output on channel change.
FA – Set [Faders / Crossfader] by channel.
PO – Set [Track & Device Pots] by channel.
SL – [SCENE LAUNCH]
AB – [# AB Solo Rec]
CS – [CLIP STOP]
FS – [FOOT SWITCH].
The colour of the two letters will denote if the extra festure has been enabled or not (RED = Default / GREEN = Enabled).
Below are the currently usable extra features.
Set MIDI output on Channel Change.
By default ARC does not output any MIDI data when using the Channel Change buttons (Track Select 1-8).
Pressing the first button along the bottom row sets this UI feature on/off. sixteen channels of MIDI CC data depending on the channel number selected.
Press it once again to turn MIDI output off.
Set [Faders / Crossfader] by channel.
This feature allows you to copy any channels fader group onto any other channel.
Press the button once and [FA] will be displayed in it’s active colour.
When GREEN you can use the 16 [#|AB] buttons to set the current channel faders to the required channel (full tutorial in the works).
Set [Track & Device Pots] by channel.
This feature allows you to copy any channels pots onto any other channel.
Press the button once and [PO] will be displayed in it’s active colour.
When GREEN you can use the 16 [#|AB] buttons to set the current channel pots to the required channels (full tutorial in the works).
Momentary / Toggle [SCENE LAUNCH] buttons.
By default ARC and the [SCENE LAUNCH] buttons are set to TOGGLE mode.
Pressing the fifth button along the bottom row of the UI changes this to it’s momentary mode. Pressing it once highlights the button as Green and you will see the letters [SL] in their active colour.
Momentary / Toggle [# | AB | Solo | Record] buttons.
By default ARC and the [# | AB | Solo | Record] buttons are set to TOGGLE mode.
Pressing the sixth button along the bottom row of the UI changes this to it’s momentary mode. These toggle values are stored into memory between the lower eight channels (1-8) and the upper eight channels (9-16) so switching between them retains their values.
Momentary / Toggle [CLIP STOP] buttons.
By default ARC and the [CLIP STOP] buttons are set to TOGGLE mode .
Pressing the seventh button along the bottom row of the UI changes this to it’s momentary mode. As before, these toggle values are stored into memory between the lower eight channels (1 – 8) and the upper eight channels (9 – 16) so switching between them retains their values.
By default the foot-switch operation is based on the active channel.
This in turn gives you 16 foot-switches at your disposal. By choosing the final [CLIP LAUNCH] button on the bottom row you can toggle this between the channel by channel mode of put it into ‘control’ mode.
This allows you to use the foot-switch as your momentary toggle between the lower eight channels (1 – 8) and the higher eight channels (9 – 16).
