Each Preset makes use of the 3 Assignable Knobs so that variations can be created or morphed to on the fly, Knob 1 tends to be tempo related controlling LFO Speeds, whereas Knob 2 always controls the Delay or Reverb amount. Knob 3 Varies depending on the preset.
The bank contains 128 presets which make full use of OS5. Additionally there is a second bank which is identical except that they are devoid of Delay and Reverb, this is provided as a convenience for those that prefer a less saturated sound. Of course adding/removing delay can be done via Knob 2 easily anyway.
