Resonance Master
Controls all voices in the algorithm. Each voice has its nominal resonance
adjusted by this percentage.
Resonance Tuning Master
Affects all voices in the algorithm. Each voice has its nominal resonance
adjusted by this value. In the musical world, the tuning reference is A=440.
This means that the note A (above middle C) is equivalent to 440 Hz.
Changing the master tuning causes all notes to be sharp or flat.
Resonator Detune
This parameter acts as an adjustment to the specified frequency for the
voice’s resonator. The calculation of cents yields a ratio which is used to
modify the specified frequency of the voice. This parameter is modified by
the Master Detune parameter.
Resonator Filter Freq
This parameter controls a lowpass filter inside the resonator.
Resonator Frequency
This parameter determines at which frequency the delay voice resonates. The
action of this parameter is determined by the state of the Resonance Mode
parameter. When a frequency is calculated for this parameter, it must then
be affected by the value of the Master Tuning parameter.
Reverb PreDelay (Predelay)
This is a delay that’s added to the diffused signal before it enters the main
part of the reverb. For all intents, it may be considered as delay that is added
to the reverberated signal. It is used to temporally separate the reverb from
the dry signal.
Reverb Spin (Spin)
This is usually simply called spin. It controls the speed of the reverb random-
izer. Spin is also connected with the Reverb Wander parameter
Reverb Time Hi Cut
This parameter, also known as Hicut or RTHC is a low-pass filter in the
recirculating part of the reverb. It represents a frequency above which the tail
dies away more quickly. In some ways, it represents the opposite end of the
scale from BassRT, and may be considered an analog of air absorption. It is
also closely tied to the Hi Cut Damping parameter.
Reverb Wander
This parameter (also known as just Wander), along with Reverb Spin, is used
to control the reverb randomizer. It controls the maximum size of random-
izer steps, and is expressed in a time value (typically milliseconds).
Room Size
Room Size corresponds roughly to the length of the longest wall of a rect-
angular room. In a more general sense, it corresponds to the overall dimen-
sion of some mythical space. This space has a geometry that causes sound
