"101-VCO Version 2 Roland SH-101 Oscillator Adaptation + RD-6 [Demo 1 No Talk]
Audio + Video by G-Storm Electro c. 2023
101-VCO has returned to the fold: the same great sound, simplified and improved tuning, and having all the individual outputs without need for an expander module. All in 12HP
Headphones or good monitors recommended.

"The 101-VCO has been re-tooled in 12HP! Version 2 continues its authentic realization of the Roland SH-101 Oscillator adapted to Eurorack: that lovely Sub-Octave Generator, that snowy Noise Generator, an integrated Mixer section to bring all the waves together.Now in revision 2: Improved tuning stability using power rail voltage references. Simplified tuning via coarse/fine tune knobs. Individual waveform outputs without need for any expander module.
101-VCO expands the original SH-101 features to reveal more potential of the 3340 chip: Triangle wave and 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 Alfa AS3340 re-issue chip at the core of the design, surrounded by eight 20mm slide pot controls. With the conventional coarse/fine tuning knobs it will provide full audio range, whether using the v/oct input or not.
Every 101-VCO is meticulously hand-crafted in limited quantities, not mass-produced, and ready to rock your modular world. Includes 16-pin-to-10-pin power connector cable.
Coarse Tune Knob | Initial oscillator frequency
Fine Tune Knob | Initial oscillator frequency, +/-6 semitones range
FM Slider | Amount that an external signal will modulate the frequency
FM TYPE Switch | LO for vibrato, HI/EXP for more dramatic frequency modulation
PULSE WIDTH Slider | initial Pulse Width amount
PULSE WIDTH MODULATION Slider | The amount that an external signal will affect pulse width
SOURCE MIXER Sliders | Adjusts the amplitude amount of each waveform going to the MIX output
SUB-OCTAVE Switch | Select between -1 octave Square, -2 octave Squrare, -2 octave Narrow Pulse
V/Oct Jack | Pitch Initial Frequency input for connecting keyboard controllers or sequencers
FM Jack | Plug in external signals to modulate Pitch here, such as LFO or envelopes
PWM Jack | Plug in external signals to modulate the Pulse Width here, again LFOs are typical
Individual Waveform Output Jacks | These jacks always output their buffered, DC-coupled signals regardless of Source Mixer settings
Mix Output Jack | This is the combined waveform output of the Source Mixer
TUNE Trimmer (on the back) | Affects the initial oscillator frequency
SCALE Trimmer (on the back) | Affects the v/oct tracking of the oscillator"
