Frequently Asked Questions

It’s a basic, stepped random – not as smooth or nuanced as some higher-end random generators, but it’s perfectly usable for creating subtle or rhythmic variation.
The bipolar output is designed to handle both positive and negative modulation, making it suitable for filter cutoff or other destinations that require DC offsetting.
Like most analog modules of this era, it's not tracking to a precise clock; slight drift is possible, especially with temperature changes, but it's generally stable enough for most applications.
