How to create a Track Launch mapping for your script

Hi all, I had this question via email, thought I would share the solution here.

In Ableton Live there is a mappable option to launch whichever clip is selected on a track.
We can quite easily replicate this functionality in a script using a ‘Reaction’ mapping type in Control Surface Studio.
I have attached to this post a simple script containing reactions which will do this for you .

After Importing the script into your copy of CSS, you will see 2 reactions:

The reaction named ‘track launch’ will launch the selected clip on a specific track. By default it is set to track 1. To change the track number, edit the line of code which is in the text input box:

If for example you want it to be a track launcher for track 4, you would change tracks[0] to tracks[3]
*note that tracks are zero indexed, meaning the value you enter needs to be 1 lower than required.

If you want to launch the selected clip on the currently selected track, use the second reaction named ‘slctd track launch’
There’s no need to edit anything for that reaction.

Thanks
