ROTATING SPEAKER

Rotating Spkr adds the famous classic rotating speaker sound to any instrument. A tunable
distortion is added to the input signal and is also passed through the rotors.
01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section. For
this algorithm we recommend higher Mix settings.
03 — Rotating Speaker Slow Speed
Determines the rate of the rotary speaker when in the "Slow" setting (parameter 05). This
parameter determines the manual level for the rotary speaker rate when Speed=Slow, or when
the selected modulator is at zero output level. The higher the value, the faster the rate. By
assigning a modulation controller to this parameter, you can change the slow speed in real time.
04 — Rotating Speaker Fast Speed
Determines the rate of the rotary speaker when in the "Fast" setting (parameter 05). The higher
the value, the faster the rate. By assigning a modulation controller to this parameter, you can
change the fast speed in real time.
05 — Rotating Speaker Speed
Determines how the rotating speaker will switch between slow and fast speeds. The behavior of
this switch accurately reflects an actual rotary speaker, taking time to speed up or slow down,
based on the value of the Inertia parameter (06). By assigning a modulation controller to this
parameter, you can change between the slow and fast speeds in real time.
06 — Rotating Speaker Inertia
Determines how long it will take for the rotor effect to speed up or slow down after switching
from slow to fast or vice versa. Adjust this parameter to simulate the effect of the rotary speaker
gradually picking up speed.
07 — Distortion Level In
Determines the input signal gain into the amplifier simulation, creating a tube-like overdrive.
Higher settings yield more distortion.
08 — Distortion Level Out
Controls the output of the amplifier distortion. There is a (fixed) clean path in parallel with the
distortion). Therefore, to eliminate distortion, set this parameter to 00.
