When I'm designing patch, I like to link this or that parameter to a live.remote~ or live.object object in my patch.
Unfortunately, when you use it natively, you have to know the index of each parameters (I wrote index, not ID)
Example: you want to link this gorgeous LFO rate. OK. You have to use a live.path etc. BUT, what is the index of this parameter ? ? ? ? you can write the path easily like that "live_set tracks t devices d parameters p" but … WHAT IS p ?
p can be found by trial & error but it is bad.
This device is designed to find that for you.
It is a kind of "index learning mode" device.
