"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

JU60-VCF is an analog 4-pole low pass filter adaptation of Roland Juno-6/60 using a vintage IR3109 chip with a BA662 OTA chip in the resonance feedback loop. This topology was also used on the Jupiter-8, with a switch for tapping the 2-pole mode. Resonance will self-oscillate and produces a nice sine wave alone. JU60-VCF won’t turn your system into a polyphonic synth, but it has a classic sound at a sweet price.

FREQUENCY | the initial Cutoff Frequency of the filter

RESONANCE | the depth of the peak frequency resonant feedback

IN1 & IN2 | Mix together 2 different audio signals, each w/ their own mix pot.

CV1 & CV2 | Modulate the Cutoff Frequency w/ any polar/bi-polar mod source.

MODE | Select between lowpass 2-pole or 4-pole operation.

T2K-VCF Transcendent 2000 Eurorack Filter Adaptation by G-Storm Electro

T2K-VCF is a Eurorack modular adaptation of the Powertran Transcendent 2000 analog filter. Wavefolded material sounds phenomenal on this, coming from Capt'n Big-O. Op Amp gain compensation means no loss of bass frequencies even at extreme resonance settings. Resonance will self-oscillate and produces a nice aggressive sinewave alone. With some coaxing you can track the self-osc w/ v/oct.
At the end you'll hear the filter output going into a phaser and delay.

"Time to get a little more serious.

SH5-VCF is an all analog Eurorack adaptation of the Roland SH-5 mixer and Dual Filter. There are no filters-on-a-chip here. The SH5-VCF uses all discrete components and quality op-amps to work its special mojo. Like on the original, the Low Pass circuit is comprised of open-collector matched transistor pairs arranged in a diode ladder configuration. The lack of temperature compensation was also respected, so while the resonance can self-oscillate the v/oct keyboard tracking is about 3 octaves at best. This same configuration used in the Roland SH-1000 and the earlier System 100 (not 100m).

The Dual Filters: VCF + BPF
| VCF | The VCF (Voltage Controlled Filter) comprises one HP (High Pass) and one LP (Low Pass) circuit in series. VCF Select switch can choose 1) HP, 2) LP, or 3) BP (Band-Pass) configuration. Due to the unique design, the HP resonance is actually derived by overdriving the LP circuit.
| BPF | The dedicated BPF (Band Pass Filter) has its own discrete circuit distinct and apart from the VCF. The original BPF circuit has been respected, but greatly expanded upon using a proprietary voltage controlled feedback path to enable frequency control via external signals. This feature wasn’t available on the original design. The original did not have a buffered output jack for the BPF neither, as the SH5-VCF does. The BPF Level attenuator will affect the main output only.

The MIXER
There are four audio signal inputs, each with its own fader pot and filter routing switch. Each routing switch can send each audio line to either VCF, BPF, or both VCF + BPF.

The 3 CV MODULATIONS – Choose Wisely
Incoming CV signals can be used to modulate any filter frequency cutoff. Signals can be up to +/- 10Vpp DC polar or AC bi-polar at the inputs.
| CV1 | has inverting and non-inverting behavior where zero is at 12:00.
| CV2 | has non-inverting behavior for both filters, and inverting available to VCF only
| KB | is a non-inverting V/OCT Keyboard Tracking control available to both the VCF and BPF, typically a Keyboard Voltage – but can be any kind of polar or bi-polar signal.

A Eurorack power connection ribbon cable is included. To get the most out of the filter experience follow your filter with a VCA. The filters require startup voltages on the low end to avoid audible thump, so there will be sub-frequency audio seepage. A post-filter VCA (sold separately) is recommended to gate the filter. Be sure to check out the G-Storm Electro 2xVCA when available.

- Use the Noise for percussion apart from what the synth waves are doing.
- Send two waves to a dual VCA, and use modulation to crossfade them.
- Send the waves to different filters, each having their own sequence.
- Toggle different waves using a 1x4 sequential switch, or the GSE Infusor-X, for wavetable-like effects.
- Send two waves to a sidechain processor like the Worng LRMSMSLR.

G-STORM ELECTRO Announces the 101-VCO in Red and Blue Panel

Priced at $235/€210 - expected release next week. You can check out G-STORM ELECTRO's gear at their Reverb store here.

"GSE is pleased to announce my first VCO module. 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. 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. When this well-calibrated beauty drops into your rack, 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. 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.
