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. Includes 16-pin-to-10-pin power connector cable.
