LE DÉCHU

CONVOLUTED ANALOG POLYMORPH VCO / LFO

LE DECHU is a convoluted analog VCO and LFO. It is equipped with an onboard VCA so you will only need an envelope generator to turn it into a full synth voice. The ALTERATION knob can act as a pseudo filter.
If you have never heard that word on an VCO before it’s because I have just made it up to respect the concept of the complex oscillator.

My convoluted oscillator concept differs from the well known classic complex oscillator. I developed around one simple concept, “no respect for the waveshaping rules”. The waveforms get divided, offsetted and strangely mixed together, resulting in unconventional waveforms and tones like strings and wind instruments or electric pianos and organs but of course : From another world ! The more you touch the ALTERATION knob, the more It sounds like a dirty old faulty synth and even cheap digital keyboards, you tweak, you got it, you name it !

Talking about waveforms, by combining the switches FULL/DIVIDED and SURGE/ODD/RIDGE, you have got a total of 6 starting shapes to tweak.
Things become extremely interesting when you are using the DECHU as an LFO, resulting in very occult voltage movements !
LE DECHU can also be used as a classic VCO/LFO using the 2 unusual : SEMICIRCLE and TRAPEZOID outputs, and the standard RAMP output. All 3 are not affected by any waveshaping and not going through the internal VCA.

Just because it’s never too much, thanks to the CLIPPING DEPTH knob, you can add a variable pulse wave to the total mashup combined with a hard clipping stage to design and drive your waveforms to a more heavy tone !

Did I forget to mention that LE DECHU means the fallen in french ?!

Besides being a freak, LE DECHU can properly stay in tune and accurately track 1v/ octave. You can even talk to bats if you feel like you need a higher range, using the internal HF tuning trimpot.
