The King Corruptor ringmod sequencer

1/27/2015

3 Comments

 
Another original ring modulator design.

This is a much more complex version of the original Corruptor ring modulator. Insted of a ordinary oscillator we have a sequencer for the carrier frequency: 8 different steps that can be configured in alot of different ways. It can also be used as a stand-alone sequencer "synth" or a square wave fuzz and it can also do regular ringmod sounds. A perfect project for those who love off-board wiring.. :P
The controls are:
VOL: overall output volume
MIX: this blends between ringmodulated signal and straight square wave fuzz
FREQ: this is for fine tuning the frequency
RATE: this controls the speed of the sequencer
Rotary switches x3: these control the order of the sequencer steps
Stages switches x3: these bypasses different steps in the sequencer
SEQ switch: this turns on/off the LFO that drives the sequencer (does not turn of the oscillator)
RANGE switch: this toggles between 3 different frequency ranges
GATE switch: This turns on/off the gate. In the off position you have a free running sequencer

Hi Greg
I got mine from Tayda. It's the 1-pole 12-position switch, model Alpha SR2611F. It can be configured for 5 positions (4-clicks) with a pin.

cheers / Fredrik

hello Frederik, after finish with sucess the "into the unknown" pedal which is so fun !!! i try to finish this one. my problem is i'm not sure about connexion of 9 v connexions on the rotary switch.
i put the rotary in five positions
connect the 9 v in the 1 pin
q1 in the pin 2- q 2in pin 3 - q3 in pin 4 - q4 in pin 5
and each center pin to his a b or c pattern.
is that correct?
i do have sound but no sequencer and no rate led and nothing on the frequency range.

thanks a lot
