Thanks! That's what we did!
I made a video showing the comparison:
Well yeah I opened it, it works but not when I insert it in my code, but I'm sure it's about onctrol.
I have found another solution!
Add knob, speed LFO knob. When you select 'not sync button' (position 1), the knob has range 0 to 50.
Until here that's the same as before.

And then add a second knob, with value 0 to 1 for synchro, then add this similar line:
And then it switches btw the two knobs, but we don't see it! 😄
I go try it, I hope it works 😛
