Hi,

I am trying to work out an expression to beat match a song.

I have two keyframes on a time remap which i want to be able to control their distance apart from a slider and loop.
I need to be to control it with a slider as the BPM is not divisible by my frame rate.

Is there an easy way to do this?

so, i've been playing around with this and this is where i've got to:

start = effect("start")("Slider");
bpm =effect("BPM")("Slider");
bar = bpm/60; 
t = ((time - start)%bar)/bar; 
valueAtTime(linear(t, key(1).time, key(4).time)) 

This is sort of working, it allows me to input four keyframes and have them cycle through to the beat however i there are a few things that I cant work out how to fix. The first issue i have is once it gets to beat / keyframe 4 it cuts straight back to beat 1 instead of holding for the full duration of a beat. Secondly, is there any way of making the keyframes snap rather than interpolate?

thanks
