Leap MoDULAtion


A Max For Live device to control any Ableton Live parameter moving hands and fingers in 3D space using the Leap Motion.

Based on aka.leapmotion external by Masayuki Akamatsu

This is a very early version. Some improvements and additional features are planned.

The device works only on Mac.

A brilliant idea, I’ve been waiting for something like this! Unfortunately it crashes Live 8.4.1 on OS X 10.6.8. I’ll keep checking for updates!

Oct 6, 2013 at 3:14am

Hi Gweilo,
the device is built upon Max 6.1 and Ableton Live 9.
I’ll investigate if it’s possible to make a Live 8 compatible version.

Thanks for your quick reply, LSKA. I actually plan to upgrade Max and Live soon, and I’m looking forward to try out your device.

It doesn´t work for me. I´ve tried to download aka.leapmotion but it gives me problems. I am with Max 6.13, Ableton Live 9 and Mountain Lion. What could be wrong? Thank you very much!

This is exactly what Max Windows appears in: “aka.leapmotion: unable to load object bundle executable
2013-10-07 21:42:59.173 Max[654:c07] Error loading /Applications/Max 6.1/patches/extras/aka.leapmotion.mxo/Contents/MacOS/aka.leapmotion: dlopen(/Applications/Max 6.1/patches/extras/aka.leapmotion.mxo/Contents/MacOS/aka.leapmotion, 262): no suitable imag
e found. Did find:

This kind of error seems to be related to 64bit support. Are you running Ableton or Max in 64bit mode?

Oct 7, 2013 at 2:30pm

Yes, both of them in 64bit mode. I was suspected about it. Thank you very much, and congratulations for your idea, I like it very much. Do you know Geco?

Oct 7, 2013 at 2:47pm

The only thing I can suggest you is to try to compile aka.leapmotion for 64 bit architecture. You can find the sources here.

Yes, I have seen Geco and it seems really interesting, especially regarding gesture support.
It outputs MIDI data based on gestures, while I was much more interested in generating continous control data for devices, and the possibilities of thus creating complex, subtle and somehow unpredictable patterns, rather than quantized values.

But I’l soon give it a try!

Thanks for your feedback!

Have you solved the problem ? I get the same message. The aka.leapmotion works perfect on my MaxMSP 6.1.3 (64bit mode) without Ableton Live 9.0.6 (64bit mode) opened at the same time.

Any suggestions ?

Hi, no, I´ve not solved it. I don´t know compile. But at least aka.leapmotion works in your Max/MSP. It doesn´t in my MacPro :-(

Oct 8, 2013 at 2:45pm


Have you tried to copy aka.leapmotion.mxo into the same folder of the aka.leapmotion.maxhelp file ?

LSKA ! Tell us something ! Fatti vivo ! dacci una mano !


Oct 8, 2013 at 2:47pm

Yes, I´ve tried it, and doesn´t work. Thank you anyway.

Oct 8, 2013 at 4:22pm

Ok. Solved. Ableton Live must be 32 bit version + MaxMSP 64 bit.

Oct 8, 2013 at 4:36pm

@Gusadel so can you confirm it is working for you in Live 32bit?

Unfortunately, I don’t have the programming skills to dig into akamatsu’s code and find a better solution for getting the external to work… I’ve tried to build aka.leapmotion against the latest SDK’s but I get this error in Max Window
aka.leapmotion: unable to load extern, object has no ‘main’ function

Oct 9, 2013 at 5:43pm

I confirm. It is working in Live 32bit.


Oct 12, 2013 at 10:20am

I Just upgraded to the newest versions of Max4Live 6 and Live 9, both the 64 bit versions and your device works fine. Keep up the good work :)


Oct 12, 2013 at 5:51pm

Hi, Gweilo, could you explain how did you do for that it works fine in Max? I can´t do it. Thank you very much in advance.

Mar 16, 2014 at 9:17pm

Guys you could try for me the beta of leapformax
