Modulation Effects
Output
Sets the output level of the Tremolo.
Rotary
The Rotary effect emulates the sound of a vintage rotary speaker including amplifier,
horn, drum, and cabinet. By emitting the sound via a rotating horn and drum, the rotary
speaker produces a Doppler effect that thickens the sound. The horn and drum rotate
at variable speed producing different amounts of Doppler effect. The amplifier of the
rotary speaker adds a warm sounding distortion, and the horn, drum, and cabinet
color the sound uniquely. The horn and drum are recorded via (virtual) microphones
that can be set to different angles to broaden the sound image. Typically, rotary
speakers are used with electric organs.
Rotation
Use this to change the rotation speed of the horn and drum (Slow, Fast, Stop). When
set to Fast, the Doppler effect is stronger. When set to Stop, there is no Doppler
effect because the drum and horn do not rotate. Because the horn and drum
accelerate and decelerate at different speeds the transition from Slow to Fast and
vice versa sounds the most interesting.
Distance
Sets the distance between the microphones and the horn and drum. The amplitude
modulation of the sound decreases with the distance of the microphones. Set this to
higher values for less amplitude modulation.
Cabinet
The horn and drum sound different when recorded through the louvers of the cabinet.
Use this to color the horn and drum with the sound of the cabinet. At a setting of
100 % you get the full sound of the cabinet.
Balance
Here you adjust the balance between the horn and drum microphones. At a setting of
0 % you hear only the drum. At a setting of 100 % you hear only the horn.
Slow
This adjusts the slow speed of the horn and drum together.
Fast
This adjusts the fast speed of the horn and drum together.
Accel
Adjusts the acceleration time for raising and lowering the rotation speed of the horn
and drum.
Horn Mic Angle
This adjusts the stereo spread of the horn microphones. At a setting of 0° the sound
image is monophonic. At a setting of 180° the sound image is fully stereo.
