Retoone VST effect

A simple, midi-controlled effect

for pitch-shifting, doubling, choir, chorus.

Two modules:

  • Pitch-shifting and three voices choir

  • Stereo chorus

Pitch-shifting: up to three indipendent voices are generated from the input. Each voice is shifted up to 1 octave up or down, with formant control. Frequencies can be controlled by midi notes. Pan control for each voice is available, with mid-side ratio control and "humanizing" parameters.

Chorus: the additional voices can work in "chorus" mode (modulated periodic pitch shift) and can be placed on the stereo field with mid-side ratio control.

KickHaas VST effect

KickHaas is a VST effect for Windows.

It is a "stage placement" effect. It gets a mono or stereo input and calculates early reflections in real time.

Place walls, source and listener, draw equalisation curves for materials and for sound perception (localisation cues, side, rear), mix early reflections to the sound in true stereo, in realtime.

Grainz VSTi granular synthesizer

v.0-4-0 released

  • 1 physical modeled "string" oscillator (plucked, bowed). Plucking/bowing position, pickup position, stiffness, damp

  • 2 granular oscillators. Loads wav mono files and "granulizes" them. From sample playing to complete destruction. Position, grain width, grain fade out, single_shot/loop, position lfo

  • Multi-stage drag-able envelopes for amplitude, grain position, filter frequency

  • Granular -> physical modeled oscillators interaction. From resonance to weird effects

  • Multimode resonant filters with resonance and "action" control

  • "Spread" effects

  • Pre-post-filter delay lines with feedback. Separate send for each oscillator

  • Arpeggiator with chord detection

  • Control matrix

  • Graphical user interface by Rick Christy

RealLS VST rotary speaker


Set four loudspeakers to a real two-bands rotary speaker



Put 4 speakers in this position (as close each other as you can)

Speakers placement

Suggested application (enclosed to get reflections)

(3d graphics by guitarzan @KvR)

  • Load the vst effect

  • The vst cuts the incoming mono signal (an organ?) in two bands. Set the crossover frequency

  • Set gain and rotation speed for each band

  • Verify that the loudspeakers are placed in sequence. The sound should sweep on a circle

  • That's all. You can test new configurations. The first one is to enclose the speakers cluster in a box, to get reflections and emulate a Leslie

There is an hardware version of this project ("hardware" page)
