APC40 Hacking Superguide: Monome Emulator, MIDI Tricks, Handshake Puzzler
Out of the box, Akai’s APC40 has some lovely features for plug-and-play control of Ableton Live, with clip triggering, track control, device control, and dedicated buttons for command shortcuts. It also sends and receives standard MIDI messages for every last button and encoder. But what if you still want more? What if you need more controls to do multiple duties, or get bored with simple clip triggering and decide you want additional interaction? Enter the hackers. Already, using MIDI, clever APC40 users are squeezing more function out of this box. And while it isn’t solved yet, there are some clues to the infamous hardware handshake – a System Exclusive string exchanged between the APC and Live that locks certain Live software features to the APC and not to other hardware you might like to use.
Manual MIDI
Before we get too fancy, for power tricks, your first stop should be Akai’s own site:
Tips and Tricks June – APC40
Live allows you to manually override the APC’s dynamic control assignments using the standard MIDI Map. Let’s say you don’t use headphones for cueing. You can select the MIDI Map, pick a control to which you want the Cue Level encoder to be assigned, and you’ll manually assign just that control – the rest of the dynamic template remains in place. Akai has some tips for scrolling through scenes, selecting scenes with one of the two footswitch jacks on the back of the unit, scrubbing and nudging clips, fine-tuning tempo control, and more.
monome Emulation for APC40 and Korg padKONTROL
Our friend Michael Hatsis of trackteamaudio has been hard at work in Max/MSP patching an emulator for the creative patches for the open-source monome hardware. (Thanks on Twitter to ruaridhTVO, too.) By translating from the (and, cough, superior) OpenSoundControl messages the monome supports natively to MIDI, the emulator supports not only the APC but Korg’s padKONTROL, as well. This opens up the use of the APC for creative microsampling and other tasks.
Video demo at top (updated late Sunday night, so if you saw this over the weekend, here’s a tighter version).

And be sure to check out the Java- and Python-powered open-source library for the monome on which Michael’s work is based:
net.loadbang.shado
You’ll find plenty of documentation in Michael’s download, and the hope is that this is just the beginning — you Max patchers out there (and Pd, if we can port this) can keep hacking on it and try out some new ideas. One reason you might want to keep hacking on the padKONTROL is that you could find uses for velocity – unlike the monome and APC, Korg’s 4×4 drum pads are velocity sensitive.
