Frequently Asked Questions
They're triangle waves, which are very close to a sine wave when the frequency is low. They're clean and predictable, not the rounded sound of a true sine.
While technically possible, they're designed primarily as LFOs. Audio rates can be unstable and the waveform might exhibit aliasing artifacts.
The sum output combines the signals from all four LFOs, with jumpers to select which are included; it’s a straightforward summation, ideal for creating complex rhythmic patterns.
