Ableton Forum

actually, I want to send program change to "chian selector" to control it

thanks for response, I found it too. but this isn't explain how to change them with program change.
any idea?

I'm new for ableton live. Until now I used MainStage to play live.
In mainstage there is a feature which called "patches". So, you can add instruments and effects for each patch.
then you can change "patches" by program change trigger(external keyboard).

I want to know how to do that in Ableton ...
