It is really easy to change behaviour of button in prime. First, to allow usage of qml file instead of internal mapping , rename file KnownDevices.vfsb to something else cd /usr/Engine/Content mv KnownDevices.vfsb KnownDevices.bsfv When doing this, we tell prime to use qml files located in /usr/Engine/AssignmentFiles/PresetAssignmentFiles// So on prime go it is JP11.

Requirements * - Serial / UART Access ( see debug_port ) * - SD card dedicated partition with linux files * - Time :) Linux image creation To be able to boot linux, we have to create a rootfs on a dedicated partition on sd card. You need to have at least one or two ( or more ) EXT3/EXT4 partition. To get enough space once you'll be jailed in your debian, its good to have at least 5/6 gb or more partition size. As an example here is mine :

To get console access via UART on Akai devices you have to proceed like on the pictures below : On my AKF i have 6 pins, sometimes on MPC there is less pins. Use an USB/TTL converter to avoid damage on your board. You can use this one as on the photo :

Below is a way to get an console access to a denon prime unit ( dont work with prime 4+ cause fw is now encrypted). Be careful to what you do and changing FW may void your warranty. Get the latest firmware for your unit : In my example i will use 3.4.0 version.

As Force is running under linux, it is possible to get verbose debug messages by enabling dynamic debug functions. To do this you can get list of avalaible functions in /sys/kernel/debug/dynamic_debug/control (Cat this file to see it ). Then to enable debug you can do :

kernel_build

Objectives of this tuto is to build module compatible with current AKF kernel Kernel version of the force is 5.15.89-inmusic-2023-01-18-rt56 To build same kernel/module as force you'll need : - Arm processor to build source, you can cross compile but it is easier to do it on an arm processor ( so you can use raspberry pi, arm chromebook etc.., on my side i use an ARM chromebook with a RK3288; same chip as akaiforce.

On AKF there are 8 Oleds display, and they can be changed via SysEx midi messages. To understand how it work I advise to read the following articles : Below are more explanation on how it works. As i understand AKF Oled are 128×32 pixels .

I encourage you to read article from thekikgen However on the force it's a bit different. when doing amidi -l you have your midi interfaces root@force:/home# amidi -l Dir Device Name IO hw:0,0,0 Akai Pro Force Public IO hw:0,0,1 Akai Pro Force Private IO hw:0,0,2 Akai Pro Force MIDI Port IO hw:1,0,0 AudioBox USB 96 MIDI 1

This page is building... To Create Prime image for Akai force you can follow this procedure. It's working on release 2.1.2. Go to Engine Prime Download and get firmware 2.1.2 : By using Thekikgen method you have to extract the rootfs image from firmware :

Prime Firmware contains some information about qml syntax. Whatever the platform, ( MPC / Windows ... ) you can take Engine Binary, open it with 7zip and extract .rdata or .rodata. In this file a part of qml syntax/objects are explained with examples.

This project is in progess, and not still finished I think the best / easier usage with force is to use prime2 or primeGo. Below i will explain / provide a template for Prime2. Prime use QML from QT to do assignments and map functions. You can write your own javascript / qml code to suit your needs.

I own a working force and a force where the internal soundcard doesn't work anymore. On my “not well working force” i use a presonus USB soundcard. With this external soundcard, i have sound output only by using prime4. To use prime 4, you have to change your productcode to JC11 when binding. (mount -o bind productcode

This wiki is dedicated to my investigations on Akai Force/ Denon Prime & Radxa rock2 box, hacks and running other things that Akai MPC Software on MPC/AKF. There is no aim to harm denon dj/akai or other of their products however i think they could have given a way to allow people launch their own vst or virtual instruments, instead of always selling new instruments like DLC.
