Select Device On/Off with Reaction?

Hi forum members,

I see that one can add mapping of type: Device On/Off from the + button in CSS to have a button on a Midi controller to turn and off Devices i Ableton.

My question is can this also be done with a Reaction?

I have looked at the various option under script and Live Object Model and I find nothing that looks like it could do the same thing!

Am I missing something here?

The first parameter in any device controls the On/Off. It has parameter number 0.
Here’s a list of all device parameters for native devices provided by Remotify.

Hi Glenn,

Thanks, but I’m not looking for the “name” that part I have figured out.

What I’m interested in is calling it from a reaction, i.e. using Ableton’s API/LOM e.g. with an if condition etc.

If you want to you use a device’s on/off setting as a condition you can use the value of parameter 0 of the device. A value equal to 0 means the device is off, a value equal to 1 means the device is on. So in the example below we only want to continue if the device is on.

Although I should mention that the path menu starts numbering at 1 for the first parameter of a device. But in the line of code it still shows as index 0 (red underlined).

Thanks, Glenn!

I don’t think I would have found it my self.
