Short of LFOs? The MOTM-380 has four of them in a compact package. The jacks are arranged in a unique way: The four outputs are individually summed, and inserting a jack into another output removes that output from the mix. You can have combinations of "pure" and "complex" modulation sources not found elsewhere.
- Four Independent LFOs
- Two triangle outputs, two sine outputs
- Unique summed output for complex modulation waveforms
- Range: 0.03Hz to 35Hz
- Low power consumption
