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.
