HI, I'm just trying to send a continuous controller to control a volume slider in Ableton LIve.
I read older messages but they don't seem to apply to my case, very straight forward.

Keystroke R rotates right : volume up
Keystroke L rotates left : volume down

That's all I need.

thanks a lot.

Hey mocker

This post above should help.

Sorry, I was not clear : I want a keystroke to send a midi message (continuous controller) and not the contrary. The post you pointed is for outputing keystrokes…

Oh, I'm sorry. At work, doing too many things at once.

You should be able to set the the outgoing message to the same as an absolute knob using a global variable.

Code: Select all

Translator 1: Volume Up
Incoming Message: Keystroke R
Rules: ga=ga+1
if ga>127 then ga=127
Outgoing Message: B0 00 ga

Translator 2: Volume Down
Incoming Message: Keystroke L
Rules: ga=ga-1
if ga<0 then ga=0
Outgoing Message: B0 00 ga

Or you can send it as a relative controller. I can't remember how to set that in Ableton, off the top of my head at least, so it listens for relative and not absolute, but you would just have the outgoing messages be whatever the offset is (either 01 and 7F or 3F and 41)

That make sense?

Great ! Works exactly as I expected. Will take a deeper look into absolute vs relative, to be sure of what I need.
