Attack - Time period for gate to open.
Hold - Time period that the gate remains fully open.
Release - Time period for gate closing.
Maximum gate open time (attack + hold + release) = 500ms.
Models:
Classic nonlinear - Emulates the faithful 80’s classic gated reverb.
Panner - Rapid panning between L and R in the reverb. Short time movement FX.
Powerbox - Max power in gated energy. Not as de-correlated as classic non-linear.
Mono/Stereo/Wide - Option to switch between mono, stereo and wide stereo field output.
Diffusion - Minimum diffusion for ‘clear’ low diffusion in the reverb decay. Maximum diffusion for ‘rich’ highly
diffused reverb.
Pitch Doubler - PitchDoubler is a stereo, pitch shifting doubler effect generating the effect of additional
voices from its input. It is based on the same pitch shifting technology as VocalShift, with the associated low
latency (<6ms), wide frequency range (down to around 80Hz) and minimal phasing / flutter artefacts. The
effect squeezes two channels of high quality pitch shifting into a single effect slot, along with further features
such as adjustable delay and modulation.
The PitchDoubler has completely independent left and right channels, which can be mixed to the left/right
outputs of the effect by means of the stereo width control.
The doubling effect is achieved by provision of time delay, and modulated pitch shift. Sliders are provided on
each channel for independent control of the delay (0 – 25ms) and the pitch shift (-100 -> +100). A pitch
modulation LFO module, with adjustable rate and depth, provides a natural variation in the pitch shift.
Delay - Sets the amount of delay applied to each voice. It is adjustable from 0 to 25ms. A readout of the
delay value is provided below the fader.
Pitch - Sets the amount of pitch shift provided, varying from -100 cents (= 1 semitone) at the lower position
to +100 cents at the upper position. The centre position corresponds to zero pitch shift. A readout of the
current pitch shift value is provided below the fader.
Width - Controls the stereo width of the two voices. At the “Mono” position, the left and right channels are
mixed equally to both left and right channels resulting in a centre pan, mono effect. At the “L/R” position, the
left voice is fed only to the left channel and the right voice to the right channel.
Level - Provides attenuation for each voice in the doubler. A level of 0dB will pass the voice without any
attenuation. A level of -6dB will pass the voice at half volume, and -Inf will zero the output. A readout of the
current gain value is provided to the bottom left of the rotary.
Pitch Mod Panel
Active - This panel presents controls for applying LFO (low frequency) modulation to the pitch shift setting.
Make sure the “Active” switch is turned on.
Rate - Controls the rate (frequency) of the LFO applied to the pitch shift. The rate is adjustable from 0.1Hz to
10Hz.
Depth - Controls the depth of modulation applied to the pitch shift. Full depth (100) means that the pitch shift
is modulated by the full amount of its current setting. If depth is 0, no pitch modulation is applied.
