I'm looking for a way to do a BPM tap tempo delay effect. The closest that I could find was the Delay RGB with all colors linked, which is at best syncable by eye and ear and seems to speed up and slow down on it's own a bit when testing with a camera and the effect applied to video feedback.
What I would like is a slider to pick the tempo (80 to 160 would be fine as a bpm range as it ends on a point that can sync with the beginning point).
A slider to select divisions of the beat (repeat every : 16 beats, 8 beats, 4, 2, 1, 1/2, 1/4, 1/8, 1/16th beat).
Possibly a different idea altogether but an FFT Filter to tap tempo would also be worth considering (mic the environment, adjust and let the beat that is heard set the tap tempo if the beat is obvious).
