Tried the beta and the lfo issue is fixed. I did however have an instance just click and cut out. The buffer became full of what looks like a dc signal maybe. In the attached screenshot you can see the buffer display is fully white and the signal out has maxed even though there is no noise to be heard, I'll see if I can reproduce it. Could be an fl studio thing, I've seen reaktor do something similar with feedback buffers,
One thing of note the lfo rates and stream rates feel like they are reversed, Normally I'd expect speed to increase by turning up the dials.
