record automation from m4l parameter control

April 29, 2012 | 1:59 pm

I’ve made a simple max for live patch which looks at incoming audio peak data and maps the data to control another parameter inside live, in this case a knob for a synth in a midi track.
When I record the session and look at the automation track for that synth’s parameter, there is no recorded automation! its just a straight line. I tried exporting the audio and it does output the track with the parameter automated but its generated each time I export the audio.
Is it possible for Live to record how the parameter was controlled while recording by the max for live patch?

You need to have some automatable live.* object (eg. number box, dial) in the control path of your M4L patch. Thus the control data will be recorded on an automation lane for this object. In doubt post your patch here.

I modified a bpatch found in the lessons folder where you have to set the track, device and parameter to control. I mapped it to a parameter which will record it’s automation if moved by a midi controller or mouse while recording.. I’m going to be researching this problem further today, maybe I missed something simple, but thought I’d reply now anyways.

I can post the whole patch too but its large and all it is doing is sending a generated 0 – 1 signal into the first inlet of this b-patch.
