Frequently Asked Questions
It inverts the CV signal, allowing you to create more complex modulation shapes or offset the LFO’s response to other modules.
The range selection is fixed by jumpers; changing ranges requires opening the module and adjusting them, so it’s not a dynamic setting.
Doepfer's pulse width modulation tends to be a little less symmetrical than some others, which can introduce a slightly organic, uneven feel – some love it, some don't.
