PROS
- • Four independent LFOs offer incredible modulation complexity.
- • Delta control allows for subtly shifting, organic rhythms.
- • Compact 4U Eurorack format maximizes patch flexibility.
- • Solid Doepfer build quality ensures long-term reliability.
CONS
- • Limited waveform choices compared to more modern LFO modules.
- • Master frequency control can feel restrictive for extreme rate changes.
- • The LED display, while functional, is a bit dated aesthetically.

Frequently Asked Questions
Delta provides a predictable, repeatable deviation, whereas a random voltage input introduces true unpredictability; Delta is great for controlled chaos.
No, the master frequency is free-running; synchronization would require external clocking via a separate module.
While it *can* be pushed to higher rates, its design isn't optimized for fast audio-rate modulation, and you'll likely encounter aliasing.
