About the Orbits Presets
The A and B presets of Orbits are de-
signed to simulate a pair of rotating speak-
ers, with A set for fast, and B set for slow.
Rate, depth and resonance settings are all
altered to simulate this speed change.
In the presets, the envelope control is
turned off, but this can be turned on to control
rotary speed dynamically. (If a pedal is as-
signed to MORPH A/B, you can use it to
control rotation speed of the rotary speaker.)
The morph rates are set to simulate the
inertial drag when the rotors are sped up or
slowed down.
