I think it’s important to point out that this only makes the parameters the right length. Unfortunately it doesn’t line the parameters up to the beat grid. You just have to get lucky if you want it to sync with anything else 
I wish this was not so. Makes it really hard to use these type of effects when playing with others, or even a metronome.
Edit: I found Using MIDI Tempo + CV to control tremolo rate parameter. It looks like I might be able to have the effect I wanted with one of the solutions there. I wish I saw it a few hours ago, before I went through the pain .
