a single droplet takes us to the depths
What happens to a medium when exposed to a single droplet of water? How about a dozen drops? And what exactly does it mean for water to be shallow? Is it able to emerge from the depths? And where do the ripples go? This patch aims to find out.
Demo
Based on the Fairfield Circuitry Shallow Water, this patch is an exploration of modulation and filter topology. Thanks to virtualpt for the initial starting point, I expanded on their patch and enhanced it to true stereo. See here for the original.
This manual has an excellent reference schematic.
All controls apply to both ZOIA and Zebu versions, unless otherwise noted.
There is a Zebu build as well. Both patches will
work on either unit, the split was made so they are optimized accordingly.
| LFO speed. CW is faster. | |
| Modulation response. CW is smoother. | |
| LFO depth. CW is more. | |
| Amount of filter modulation. CW is more. | |
| Wet/dry mix. Goes full wet at 100%. | |
| Overall patch volume. | |
| LPF resonance amount. CW is more. | |
| Sets the minimum frequency on the LPF, similar to the internal trimpot on the pedal. |
See schematic for details but essentially the modulation for the vibrato and filter is set here using two random clocked LFO's and a set of CV logic (multipliers, CV filters, etc).
Stereo in, 2x Haas stereo spread for vibrato, 12dB LPF, audio balance for wet/dry mix, compressor, dual OD (pushed), stereo output with gain control. Comp and overdrives are on the following page.
