Version 1 Effects


What's the difference between the Green and Blue versions of the Modules?


The Green ones are Monophonic, meaning that the signal received by the effect is treated as a single signal, not as discrete voices. The Polyphonic Effects load multiple copies of the effect, and are thus able to treat each voice separately, but they use more DSP. 

The difference can be likened to 3 guitarists all playing into a mixer and the resultant signal being processed by a single effect pedal (monophonic) as opposed to 3 guitarists, each of whom has their own effect pedal, who send their signal to the mixer after it's been through the effect (Polyphonic) (except, of course, that each guitarist must be using the same settings on the pedal !)


The percentage in brackets is the DSP load on one single Sharc chip, taken from the PlanetZ charts.


Chorus (5.3%)

A mono to stereo effect, and thus best used last in the signal chain. Used to 'fatten' sounds, producing the effect of many voices from one. Choruses work by layering two identical signals with a slight delay between them.  The delay time is altered periodically by an internal LFO whose rate and depth can be controlled by the rate and depth controls. Control the amount and phase of the delayed signal by using the Mix1 & Mix2 controls.

Mono Delay
A delay produces 'echoes' of the original signal, at intervals specified by the Time control. The Feedback control determines how much of the repeated signal is routed back to the input, and hence how many times the delay will sound. The High Damp can be used to create a natural sounding fade as it removes a portion of the high frequency in the feedback signal with each successive pass. Dry and Wet determine how much of the treated and untreated signal passes through respectively. The bypass button 'kills' the delay, allowing the original signal to pass through unaffected.
Mono Distortion (1.6%)

Output can be chosen between Soft and Hard distortion - Soft is similar to the effect  brought on by Analogue tape saturation, whereas hard is produced by 'clipping' the signal, resulting in an edgier tone.
Poly Distortion (1.6%)

Polyphonic version of the above.
Pan (2.1%)
Allows a Mono signal to be placed within the stereo field. The setting can be static, or the amount of panning can be modulated externally via the Pan Mod input.
Auto Pan (2.1%)
As above, but the amount of Panning is controlled by an internal LFO. The depth control determines how much panning will occur (how far left and right the signal will pan) and the rate determines the speed at which this panning will occur. 
Auto Pan M1 (3.2%)

As above, but the depth can be controlled by the Depth Mod. This would allow you, for example, to trigger the panning using an envelope with a slow release time.
Mono Decimator (2.5%)

Decimation means literally 'to kill one in ten' , but in this case it simply means to resample at reduced bit resolution and/or sample rate by a user determined amount.  Effectively, the signal is being resampled before being output.

Both bit resolution reduction and sample rate reduction can be switched on or off. The results can range from mild distortion to quite harsh digital aliasing and quantisation noise. Use it to achieve that sought-after 'lo-fi' effect!

Poly Decimator (2.5%)

Polyphonic version of the above.
Mono Quantiizer

Reduces the internal  precision of the signal processing. The lower the value the lower the number of bits used in computing the signal. At low values you will get noticeable 'quantisation' artifacts, as the signal is 'rounded' down and the precisions of the signal is lost.
Poly Quantizer
Polyphonic version of above.
Mono Audio Mod (1.3%)
The Audio Modulator is similar to a VCA. The Offset control sets the initial gain, so that an adjustable amount of the input signal between zero and 100% is always fed to the output. The Mod 1 and Mod 2 inputs accept bipolar control signals which can then increase or decrease the base gain set by the Offset control. Each Mod input has an associated depth/polarity control. 
Poly Audio Mod (1.3%)
Polyphonic version of above.
Mono DC Blocking Filter (1.6%)

DC offsets is a constant (inaudible)  shift of the signal from the Zero crossing level and can occur in Audio Material as a result of A/D conversion, or (eg) if a dynamic microphone (which needs no phantom power) is connected to a preamp with phantom power. It can also occur in modular synthesis. 

DC offset uses up headroom unnecessarily, can cause clicks and pops during editing. and playing material with a DC offset for a long time has been known to damage speakers.

The DC Blocking Filter eliminates DC offsets from Audio Material. The DC offset is detected and corrected automatically.

See this article on for an excellent introduction to DC Offsets.

Poly DC Blocking Filter (1.6%)
Polyphonic  version of above.

This module mixes two input signals to a single audio output. The signal ratio can be adjusted manually, or by using a modulation source.

Should arguably be in the Mix/Level section, but has been placed in Effects instead.

Ring Modulator (0.4%)
Should arguably be in Effects, but is in the 'Special' folder.

The Ring Modulator is an amplitude modulator effect which produces its output by simply multiplying its two (audio) input signals by one another. Since there's no built-in gain offset, the Ring Modulator produces output only when there are signals present on both inputs.
