G-Storm Electro 101 VCO (Red) (original version)

I have gone back and forth on this one a lot. Ultimately, I have a lot of redundancy for this voicing in my rack, so I am parting with this. It is a great module, though.

CEM3340 VCO Adaptation from the SH-101

There are many 3340 VCOs out there, but none like this.

The 101- VCO is an authentic realization of the Roland SH-101 voltage controlled oscillator adapted to Eurorack. The 101-VCO packs a dizzying 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.
