Hi, I'm new to the FV-1 game. Is it possible to generate a 2nd or slave LFO that has a controllable phase offset from a master LFO?

Thanks.

Each LFO puts out +/-sin and +/- cos so you have 4 phases all 90 degrees apart from each other. If you need it to be an arbitrary phase then it is not possible.

I see, thanks. Could an allpass applied to an LFO to give arbitrary control over the phase?

Haven't fully thought this through but you should be able to do it using the ramp LFOs, you could run them both at the same speed but reset one of them at any point along the other, this will give you what ever phase difference you like.
The ramps can be rectified to give triangles and clipped or filtered to give something approaching a sine.

thanks, I will look into that.

Good old math might be useful:

sin(x+y) = sin(x)*cos(y) + sin(y)*cos(x)

y could be the arbitrary Phase offset

Yeah, rocket512 is right, that would probably work.

I looked that up right before asking my question too! Thanks all.
