G-Storm Electro 101VCO + 101VCF 2020s - Black

101-VCO
The 101- VCO is an authentic realization of the Roland SH-101 voltage controlled oscillator adapted to Eurorack. The 101-VCO packs an array of the original circuit features sorely lacking from other modules: that lovely Sub-Octave Generator, that snowy Noise Generator, an integrated Mixer section to bring all the waves together, and a dedicated octave Range switch.

101-VCO also expands the original features to reveal the full potential of the CEM3340 chip: Triangle wave, Hard and Soft sync, Exponential FM. And 2 flavors of Linear FM: Lo Range to find those vibrato sweet spots, and Hi Range for full-on Linear FM madness. Expand the palette of original sounds using an external CV signal for Pulse Width Modulation that is summed against the initial Pulse Width amount. While the initial PW amount can go right up to the edge of vanishing, PWM can take the Width right down to 0% up to 100% for complete cancellation.

Great care was taken to keep the 101-VCO fully analog circuit as close to the original as possible. Featuring an OnChip CEM3340 re-issue at the core of the design, surrounded by nine 20mm slide pot controls. The CEM3340 pitch tracking might become the standard by which you track your other oscillators. You will always be close to the correct center frequency when you boot your system, there is a fine range +/- 3 semitone Tune slide pot that can get you there.

Dimensions 14HP, 25 mm deep, Current Draw 24 mA, +12V18 mA -12V0 mA 5V

101-VCF
This is no emulation, this is the 101- VCF: a faithful adaptation of the Roland SH-101 low pass resonant filter circuit in a slim, skiff/boat-friendly, 8HP Eurorack format module. It has that un-mistakable sound not found in any other Eurorack clone.
Great care was taken to keep the 101-VCF fully analog circuit as close to the original as possible including: a rare OTA filter chip, resonance feedback bias, and thermistor frequency stabilization.

The 101-VCF is a little blue beastie that wields two audio IN jacks with a MIX pot. Two CV IN jacks w/ signal attenuation pots allow you to modulate frequency with any two polar/bi-polar signals, low Hz up to audio rates.
