My modular synth project yusynth #000

This page is dedicated to my new and ever-growing project of building a modular synthesizer.
Right now, I see no limit to it, it may grow ever and ever... That's what makes all the fun !

Filters and resonators

Steiner VCF : two different versions of this wonderful filter

ARP VCF :
a clone of the 4072 ARP filter

Minimoog VCF :
the must have filter

Diode VCF :
the sound of the famous EMS filter

JH-Tau-Phaser :
a brilliant design by Jürgen Haible

Fixed resonant filter bank:
A module for shaping timbres and resonances...

Signal and CV generators

VC-LFO:

two versions of a voltage controlled LFO

VCO:
the necessary module

Random module :
Noise generator and Sample & Hold

CV standard :

scaled voltage reference giving octaves and semitones

ADSR :

classical but efficient design

Auto-bend:
briefly gliding pitch on note attacks

Dual Gated Slew : for gated portamento and glide effects

Quadrature-LFO:
a VC-LFO with phase shifted sinewaves (0°,90°,180°,270°)

Signal processors and modifiers

MinMax :
a not so common module for voltage processing or wave distorsion

Wavefolder :
a module for generating overtones

Dual Balanced Modulator :
a dual ring modulator

Saw-animator :
Saw phase shifters

Simple VCA :
a simple though efficient VCA

audio/CV Mixer:

2 versions of signal/CV mixer

in design

Output mixer & VC-panner:
This an utility module, it is an audio mixer with tone control and headphone output. Each of the 4 voices has its own VC-panner.

Control/GATE generators and modifiers

Dual Gate Delay :
Gate delay and slew up

Dual pulse Delay

Random gates :

8 gate signals in a random sequence

Clock divider:
a triple divider to drive sequencers

Comparators: generate GATE and PULSES depending on an input signal and a threshold

Boolean Logic:

Dual AND gate, single OR gate, NOT gate
