Foot Control

• Left foot switch starts/stops drumbeats and filter sequences. If held, decrements preset. Both pressed and held states are reassignable to one of 55 options.

• Right foot switch turns on/off a specific effect, set uniquely for each active preset by the Effect Switch setting. If held, increments preset. Both pressed and held states are reassignable to one of 55 options.

• 2 external Midi expression pedals may be individually set to control one of 20 parameters, set uniquely for each preset.

• 10 external Midi foot switches may be individual set to control one of 55 assignments, set globally.


Modulation Effect processor

• Mod Effect (Tremolo, Filter tremolo, Flanger/Chorus, Rotary, Vibrato, Random Filter, Random Flanger, Tremolo sequece, Filter Sequence, Arpeggiator sequence, Auto Filter, Talk Box, Volume Envelope, Auto Pan, Wah Pedal, Fixed Filter, Fixed Flanger, Sci-fi.)

• Variation (between 5 and 21 variations for each Mod Effect setting)

• FX/Dry (blend of filtered and dry signal)

For Env Gen Effect Types, sets one of 100 combinations of 10 attack and 10 decay times ranging from 10 ms to 3 seconds.

• Depth (sets modulation depth, either positive or negative)

• Frequency (sets filter initial frequency)

• Resonance (filter resonance)

Note: Sequencer is always 2 measures, configured as 32 x 16th notes, 24 x 8th triplets or 16 x 8th notes. Swing level of 16th note follows drumbeat's swing level. Each step includes programmable level and envelope generator on/off.

• LFO Wave (set by Mod Effect and Variation but adjustable afterward. Options are Triangle, Sine, Sawtooth, Square and Random)

* Filter Type (set by Mod Effect and Variation but adjustable afterward. Options are lowpass 2 pole, lowpass 4 pole, bandpass, highpass, notch, flanger/comb, flanger/comb inverted, amplitude)
