On Gaz Williams’ Neutron stream he shows that you can move between oscillator shapes, or snap between them. The same goes for the LFO.
The LED next to the LFO will show you the current voltage. Overdrive LED will tell you if you’re clipping. S&H LED will show you the current S&H voltage it will spit out. Volume LED will show you if you’re clipping (presumably pre-volume knob).
