Voltage Controlled Eurorack Oscillator

an unique way to make sound ! 

The GR11 Voltage Controlled Oscillator is a simple but powerfull SAW core oscillator tuned for bass applications but also applicable as semi-LFO. The GR11 VCO generates four waveforms (SAW / SQUARE with PWM / TRI / SUB SQUARE ).

The GR11 has a unique SUB section which generates a square waveform that can be adjusted in four parts. Extremely well applicable for bass! Use it as LFO or even as simple voltage / frequency controlled 4-step sequencer or modulate a second GR11 for wide range of deep sounds or FX.

Eurorack Voltage Controlled 2 -pole Lowpass Filter

Let your productions scream !!

The characteristic and distinctive feature of this filter is the high feedback / resonance. The almost unlimited feedback circuit produces a cheeky sound. be aware your speakers and ears !

Because of the high level of factory tuning, the amplifiers are against the limit and therefore give a warm sound. A level control / mixer at the entrance allows you to make a further change in the sound.

Advised use of input mixer or a limiter on the output at high resonance settings!

Very skiff-friendly design. 26mm depth ( without Knobs incl ribbon connector ).
