The effect cartridge for the Z-DSP features eight chorus effect which wonderfully give life and movement to the sound from subtle to intense modulations.

1> Dual Chorus
Independent chorus lines for Left and Right outputs. Each is modulated by a sine LFO with individual control for the speed of the LFO. The center control sets how deep the modulation sweeps.
RateL – Speed of Left output LFO
Depth – Amount of modulation sweep for both channels
RateR – Speed of Right output LFO

2> Dimension?
Two chorus delay lines modulated by a single triangle LFO. The orientation of the LFO and signal phase are inspired by a classic 80s studio rack device. Unlike that unit, this algorithm offers both LFO rate and the depth of the modulation sweep. A High Pass Filter control removes low end from input for a clearer sound. This effect sums input to Mono, and works best with the Mix setting mostly or even fully wet.
Rate – Speed of LFO modulation
Depth – Amount of modulation sweep for LFO
HPF – High Pass Filter cutoff

3> Ensemble
The ensemble effect is one of the most classic synth effects. Originally made using analog BBD chips, ensemble circuits gave the string synths their ‘string’ sound. This ensemble is derived from that circuit where a slow and fast LFO provide the distinctive ‘string’ modulation. For maximum string synth effect, set the mix fully wet and feed it saw waves. The center control is for the amount of vibrato – the classic setting is about 35% or so. A High Pass Filter control removes low end from the input which adds clarity and makes the sound less wobbly. This program sums the input into mono, but has a wide stereo output and works well 100% wet.
None
Vibrato – AMount of vibrato in output mix
HPF – High Pass Filter cutoff

4> 6 Voice Chorus
This is a classic multiple delay line Chorus, found in high end studio effects, that uses 6 independent delay lines which are modulated. This program uses two sine LFOs with individual control for the speed of each LFO. The center control sets how deep the modulation sweeps. The chorus taps are panned across in stereo and have subtle feedback internally.
RateL – Speed of Left output LFO
Depth – Amount of modulation sweep for both channels
RateR – Speed of Right output LFO

5> Dual Flange
Same basic algorithm as Program #1, but with shorter delay times and a feedback control. Independent delay lines for Left and Right channels. Each is modulated by a sine LFO with the rates slightly offset for stereo effect. The center control sets how deep the modulation sweeps.
The Feedback control sets the internal feedback amount for more resonant flanging.
Rate – Speed of Left output LFO
Depth – Amount of modulation sweep for both channels
+/-Fdb – Amount of positive or negative signal fed back into delays

6> Diffuse Chorus
Independent chorus lines for Left and Right channels made from allpass delays that would normally be the input ‘diffusion’ section of a reverb. Chaining a few of these delays in a row makes for a cross between a chorus and very small room (add external feedback for more reverb tone). Each delay is modulated by one of two sine LFOs with control for the speed of the LFOs. The center control sets how deep the modulation sweeps.
Rate – Speed of LFO modulation
Depth – Amount of modulation sweep for LFO
HPF – High Pass Filter cutoff

7> Random Chorus 4 Voice
Four independent chorus lines split between Left and Right channels. Each is modulated by a random walk algorithm with individual control for the speed of the LFO. The Left/Right controls set how deep the modulation sweeps. The randomness of the modulation is a secret of many high end studio devices. Internal feedback adds fullness to the sound and at high levels imparts a small room type ambience. The pitch wobble can be less noticeable compared to using periodic waveforms for modulation, but at extreme settings the effect is like having a few too many pints at the pub!
DepthL – Amount of modulation for Left side LFO
Fdbk – Amount of signal fed back into delays
DepthR – Amount of modulation for Right side LFO

8> Tri Stereo Chorus
Three delay lines are panned Left, Center and Right in a configuration similar to some rare guitar and electric piano effect units. Each is modulated by quadrature outputs of the same sine LFO with control for the speed of the LFO. The center control sets how deep the modulation sweeps. A High Pass Filter control removes low end from the input which adds clarity and makes the sound less wobbly. This is summed mono input and very stereo output – try 100% wet!
Rate – Speed of LFO modulation
Depth – Amount of modulation sweep for LFO
HPF – High Pass Filter cutof
