Parameters for the Rotary speaker are:
– Horn slow / fast: adjust the speed offset of the horn for when the speed is on
slow or on fast.
– Bass slow / fast: same as above but for the bass rotor.
– Horn up / down: adjust the acceleration and deceleration times of the horn for
the transitions between the slow and fast speeds. When the brake is engaged,
the power is taken off from the motor so the horn slows down until stopping
only driven by the centrifugal force, so the time between fast and stop may be
longer than from fast to slow.
– Bass up / down: same as above but for the bass rotor.
– Balance: adjusts the balance between the horn and the bass rotor.
– Ambience: a real amplifier stays in a real environment causing the
microphones to capture the sound reflections as well as the direct sound
coming from the speakers. This parameter adjusts the amount of
environmental reflections.
– Cabinet: adjusts the amount of resonances caused by the wooden cabinet.
– Mic Angle: adjusts the angle between the two microphones at the horn,
ranging from 0 (both microphones in the same spot) to 180 degrees
(microphones at the opposite sides of the cabinets). This simulation considers
only three microphones, two for the horn and one for the bass rotor.
– Mic Distance: adjusts the distance between the microphones and the cabinet.
A longer distance results in more sound dispersion, a shorter distance results in
a deeper proximity effect.
– Horn EQ: not all vintage rotary speakers have the same quality for what
concerns the sound coming from the horn, some are brighter, some are duller
or maybe just well balanced. This parameter lets you adjust the treble response
of the horn sound.
– Mid reflections: adjusts the amount of sound reflections happening in the
middle of the stereo field.
– Doppler intensity: the so called “Doppler” effect is the fundamental of the
“Leslie” effect that causes the sound to be cyclically untuned while the sound
source (the speaker) gets farther or nearer to the listened; this parameter lets
you adjust the amount of this effect that is mostly caused by the sound
reflections over the walls around the amplifier.
