There is no visual information for phase on LFO like there is on the oscillators.
I consider this very illogical since oscillators have this feedback. Also the G-env also have this function. But not the LFO, I find that very strange.
Very easy to test this no need explaining the steps taken. Just do lfo at slower pase, move phase knob while having it on retrig and map a function for it to modulate.
