IOS -> Osculator -> Abelton Live * midi mapping issue

Hello everybody. I’m building a custom iPad app and I’m looking to use Osculator to hook it to Abelton Live. I know next to nothing about Abelton really so I need a bit of help here. This isn’t really an OF question, but I’m hoping someone here may be able to help. Reading this may be confusing, so I’ve made a quick video you can view to see the issue more clearly.

This is a simple test application. At this point I just want to iron out the methods of communication between my app and Abelton so I can plan out all the knobs, effects instruments, etc. The app is sending OSC messages, Osculator is receiving them and they’re being picked up by Abelton, as you can see in the video (simpel midi notes work and play sounds). This is fine for simple midi notes, but I need midi CC signals so I can adjust all the fun stuff. From what I understand this means making midi maps and Abelton should be displaying the midi messages it receives in midi map window. But I don’t see it being populated by anything. Any ideas?


Two things to check:

  • your scaling between OSC (e.g. 0.0 to 1.0) and MIDI (0 to 127). There’s a second page icon in the upper right hand corner in OSCulator to view all the scalings

  • your Ableton Live MIDI preferences need to have both Track (for Notes) and Remote (for CCs) inputs enabled from OSCulator

Does that help?

First thanks for responding. I’m not sure I understand though.

in Osculator are you talking about the parameters tab?

and in Abelton the midi preferences?

what specifically in these need adjusting?

No, in OSCulator, the little arrow button here:

When you click that little arrow button, you get a second page in OSCulator just showing the scalings, like this:

And in Live, this should be all you need to solve this issue:


you also can have a different approach, using LiveOSC OSC communication with ableton. Then, no need os OSculator, and you will be able to do a lot of things. Also check the midi-remote-script patches…

I have done an app that communicates via custom LiveOSC and midi remote… developed in OF.

Thanks all! That little tiny arrow sure was hidden for something so important. With that and another answer from the Abelton forum I’m up and running.

The LiveOSC thing looks interesting as well I may have to check that out.
