About This Listing

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

The 101- VCO is a 14HP 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.

Most of all - that sound you’ve been wanting. Needing. Waiting.

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. The 101-VCO is tested and calibrated before I send them out, but an initial tweak of the tuning and tracking may be required to account for variances in different systems.

There’s even a 5-pin header on the back panel: it’s for a future planned expansion module (sold separately) providing all buffered, DC-coupled individual wave outputs. Every 101-VCO is meticulously hand-crafted in limited quantities, not mass-produced, and ready to rock your world.

Be sure to check out my other cool modules available in my Reverb store.

“Excellent sounding Oscillator to complement the 101 filter, so good in fact I have OSC/FILT in both Red and Blue .” –Mike C.

“Sounds amazing and certainly has the vibe of the sh101 oscillator! Highly recommended!” –E.D.

“This is an amazing VCO as well. I already own Tonus and 4023 VCF. When this 101 VCO filters though those units, it sounds really amazing.
More than Roland original sounds, Thanks for this module!” –Toshio, Japan

“This osc sounds so good, first time (combined with g-storm sh-2 filter) I have ever gotten a Roland sound out of eurorack. I also found that having the waveform mixer right on the module was very performable, and a welcomed feature.” -BK
