Scatter — a stereo reverb/tremolo with some interesting tricks

This patch was inspired by some of the ideas used in the Champion Leccy Skitter pedal. That pedal allows a tremolo to be used on the dry or reverb signal path, but also allows you to invert the phase of those tremolos, so as the reverb path diminishes, the dry path increases in volume.

I took that idea and added to it, utilizing some of the potential of a stereo signal: the phase of tremolo on the right side can be offset; this offset can also be modulated. There are also controls that allow you to randomize the shape of the tremolo per beat, which can be randomized on both sides, or synced. I really like a choppy tremolo, so the depth of the tremolos actually goes to 200%, allow you to introduce periods of silence between each rise in volume.

I also had some CPU left over, so I placed to a granular module before the reverb, primarily with the intention of using it for pitch-shifting/shimmered reverbs.

The patch is stereo throughout.



Left — tap tempo (also accepts MIDI clock); there are clock dividers on the second page that control the division of the tremolo and of the phase offset modulation

Middle — turns the phase offset modulation on and off

Right — freezes the granular module, so you could capture a sound and play over it if you wanted


There is a wet/dry mix in the top right corner (lime).

In the middle of the patch are pixels which show the tremolo condition of the dry (top, blue) and reverb (bottom, aqua) per side.

The depth controls for the dry and reverb tremolo are color-coordinated with the pixels. Additionally, at the top, beside the dry depth control are two pushbuttons:

Invert — will invert the phase of the dry tremolo from the reverb tremolo

Invert switch — this will cause the right dry tremolo to be inverted by the left reverb LFO, and the left dry tremolo to be inverted by the right reverb LFO (this can create some really interesting stereo patterns)

On either side of these pixels are controls for the tremolos in purple and magenta:

On the left are shape controls: the shape moves from sine, to square, to triangle, to sawtooth, to ramp, to random.

There is a swing control which lets to shape the symmetry of the wave.

Beneath these are pushbuttons:

Random wave — randomizes the wave per beat, this randomization is different for either side

Random wave sync — same as above, but with the random wave synced per side

On the right side are phase controls:

Phase offset — sets the offset of the right side’s LFO, from 0 to 180 degrees

Phase offset depth — when the phase offset modulation is on, this will set how many degrees the phase offset sweeps through

Below this is the stompswitch module that turns on the phase modulation; when lighted, the phase modulation is on.

In the bottom left corner are controls for the reverb (red):

Reverb decay — sets the decay of the reverb

Low eq — lets you cut or boost the low end of the reverb

Reverb LPF — can be used to shape the highs of the reverb

In the bottom right corner are controls for the granular module:

Pitch — sets the pitch-shifting

Pitch mix — sets the mix between dry and granular module before the reverb

Grain size — (also controls the texture of the granular module) can affect the tone or texture of the granular module as well as determines the delay before the granular module comes in

Position — can be used as a pre-delay; the granular module is also fed back into itself, so this can work as a sort of pitch-shifting delay before the reverb (or just a regular delay when the pitch is set to A0)
