BitCrusher
This effect emulates the digital distortion that occurs when lowering the bit-depth or sample-rate of an audio signal. Adjust the bit-depth with Bits
control and the sample-rate with the Freq control. The effect also includes a Drive control for adding distortion.
Like the BitCrusher effect, it features pre-distortion high-pass and low-pass filters before the distortion stage, as well as similar Dirty, Clean and
Tone controls.
RingMod
This effect is used for radical timbral shifts and experimental effects. It multiplies the input signal with its internal oscillator, the shape and pitch of
which are set with the
Mode and Pitch controls. The Drive control sets the amount of distortion on the input signal.
TinCanVerb
This effect is a recreation of a low-end room reverb unit, perfect for emulating ‘cheap and nasty’ onboard synth FX. Use the included Overloud
Breverb Plate device for high-quality reverb FX.
As well as the ubiquitous
Size, Decay Time and Damp parameters, TinCanVerb features Pinch and Squeeze controls for manipulating the room
shape, while the Freeze control loops the current reverb buffer indefinitely until it is turned down again – useful for dubby special effects.
NoiseGate
The Gate attenuates the signal until its amplitude reaches the Threshold level. The Attack and Release controls set the speed at which the gate
opens and closes after the signal goes above or below the threshold, while the Hold control forces the gate to remain open for a certain length of
time after it is opened.
The
HPFreq and LPFreq controls allow you to high-pass and low-pass filter the signal used for the amplitude-detection circuit, while the Key
Listen button allows you to listen to this signal.
Increasing the
Hysteresis control smooths the gate’s response, at the expense of sensitivity to small changes around the threshold level.
Env Shaper
The Envelope Shaper allows you to adjust transients and change the dynamic shape of a signal in a different way to using a compressor. The
Sensitivity control adjusts the Env Shaper’s peak detection circuit. Detected peaks are affected by the Attack and Sustain transient processing.
The
Attack control adjusts the intensity of the attack phase of transients in the audio. Increase the control to intensify attack transients, and
decrease it to soften transients.
The
Sustain control adjusts the intensity of release portions of transients in the audio, which increases or decreases the apparent sustain of
sounds in the signal. Increase the control for more sustain, and decrease it for less sustain. This control is useful for adjusting the perceived level
of ambience in a channel. Very low settings can produce damping effects for drum sounds.
The processed signal level can be adjusted using the
Gain control, between -12 dB and +12 dB.
Breverb Plate
The duration of the reverb tail is dictated by the Time and Size controls, while the Diffusion parameter adjusts the degree to which the initial
echo density increases over time. The Predelay control adjusts the time that elapses between the input signal and the onset of reverberation.
The Shape control dictates the contour of the reverberation envelope. At the minimum setting, reverberation builds explosively and decays very
quickly. As the control is raised, reverberation builds up more gradually and sustains longer.
The
Low control sets the frequency under which the reverb effect is attenuated, while the High control sets the frequency over which the reverb
effect is attenuated.
