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 !
Hall of fame
Most recent stuff : A bit more about the cabinet
During the past years some people around the word have built yusynth based modulars. Here are some beautiful achievements.

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


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


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



Sequential Router :
To be used with sequencers
