I have found that Smoothing on the LFO is impossible to turn totally off.
The value is 0.000976562 at it’s lowest point and seems like it is impossible to make it 0.0. This mess with the waveform when using the LFO as envelopes and drifts every single note. For example when I make a basic kick using a sinewave the LFO drift and the phase get messed up.
I think I have the same issue. I midi mapped the lfo rate to my launchcontrol xl. When manipulating the rate with the controller it’s impossible to set the rate back to zero using the controller. It always goes to the value of 0.755. I tried different plugins , I couldn’t replicate the problem, so I believe it could be problem with vital.
