@lalalandsynth yes at this moment it is triggered with a note on, or I should say retriggered, because if you run it in a host it will start as soon as you hit playback, and yes you can set it to stop anywhere inside 2 cycles (I was thinking of expanding the range but I implemented a fade out instead, also a fade in function.
At the moment the fade out and in functions also plot the curve at the same time and it is a bit risky because it demands a lot of the processor in your machine, it could crash, however you can comment out that code, it's marked in the code.
I wanted the curve to reflect the fades but it's not needed for it to work, you'll still see the fades on the dot :)
Talking about triggering, you could also connect the "trigger" button to whatever you want to trigger the lfo.
And in the Y-axis callback you set the parameters to be affected by the lfo
This snippet is something I have plans for to implement in other projects, I have a FX Slots idea and I want this to be a part of it, and other projects as well, so it's not a ready plugin to stand by it self
