Modulate Your Modulator All the standards — Chorus, Flanger, Phaser as well as Rotary, Tremolo, and Vibrato are there. Also included is the unique Undulator effect from the H8000 and a RingMod that lands somewhere between ring modulation and synthesis. The dedicated SLOW/FAST footswitch for ramping the LFO rate comes in handy. LFO rates can also sync to Tap Tempo and MIDI clock.
