Garden Reverb
A reverberation module with a special lo-fi feel reminiscent of the early electronic reverb machines of the seventies and possessing a somewhat 'psychedelic' flair due to the extensive pitch modulation capabilities that are provided by its two pitch shifters.
What the Controls do
- Early (or in full: Early Reflections Size) determines when the reverberation tail will set in - immediately or with a delay.
- Decay determines the length of the reverberation tail.
- Wet-Mix - well, that's obvious.
- Color controls the overall brightness of the reverberation (actually it is a lowpass filter before the loop).
- Size controls the size of the sixteen imaginary reverberation chambers that make up the effect.
- Diffusion controls the reflectivity of these chambers - high values give a more 'foggy' sound.
- HF Damping determines the degree to which high frequencies will gradually be dampened within the reverberation tail.
How the two pitch-shifters work
The 1st pitch shifter - a a LFO-controlled pitch vibrato - has been placed in front of the reverberation loop. The speed of its LFO as well as its effect on the reverberated sound can be controlled by the Vibrato Depth and Vibrato Rate knobs.
The 2nd pitch shifter with adjustable transposition ratio and dynamic modulation has been inserted within the loop - mainly in order to produce the famous Brian Eno / Daniel Lanois 'shimmer' effect. To get its original form, the Transposition knob has to be turned up to 1200 cents (an octave) - now every time a sound event reiterates through the loop, it becomes doubled in a higher register, creating an auditory impression analogous to the experience of refracted light. For achieving other effects, remember that 100 cents make up one equally tempered semitone, so -1200 cents will add deeper registers instead of higher ones. Still different ratios will even produce even stranger harmonic admixtures.
PS: The Sequence Pendulum module has been equipped with a dedicated mode for sequencing exact transposition ratios via the Transpose Ratio Modulation Jack. This provides a patching option that will turn the 'Garden Reverb' into a kind of sequenced harmonizer.
