Flame Clockwork Sequencer / MIDI-to-CV Converter Eurorack Module

Note: links to listings are affiliate links for which the site may be compensated.

"The Flame Clockwork is a versatile clock and tempo generator. It's designed to generate clock/trigger/gate signals for clocking units with tap and clock inputs, to fire envelopes or to control sequencers and sample&holds. The clock can also be shuffled and shifted before/after the master clock!
Additionally it can send MIDI clock and a fixed MIDI note per channel. Some controls transmit MIDI control data and there's also a simple MIDI/CV interface.

specifications:
analog clock + cv-outputs
3 channels with beat-, gate-, shift / cv-control
beats included triplet and punctuated notes
clock shift forward and backward
lfo (synchronized), 4 waveforms: saw, up, down, up-saw-down
shuffle control (8 or 16th parts)
integrated midi to cv interface (5 octaves, 1v/oct operation)
midi-sync (internal/external tempo via midi-clock)
complex random functions
record functions
midi-controller
outputs 3,5mm mono jacks (1/8th inch): gate, cv + sum, clock/gate, midi-
cv/gate, sum cv, 16th clock

Cyndustries Zeroscillator - Eurorack / Doepfer Synth Module

"About the Zeroscillator:
Dr. John Chowning first described FM Synthesis technique in 1967. Since that time, no analog quadrature oscillator with through-zero capability and dynamic linear FM control has been commercially available... until now!

Cyndustries is proud to announce a major breakthrough in analog VCO design, the amazing Zeroscillator.

Liquid Smooth Analog Design

The Zeroscillator is a full-featured electronic-music-quality analog VCO capable of linear frequency modulation through zero hertz and into negative frequencies. This makes it capable of the FM Synthesis stuff, wild and crazy sounds simply not available from traditional VCOs, and timbres not available from digital FM synthesizers. Of course, Zeroscillators also make insane LFOs!

Traditional FM Synthesis oscillator implementations, such as the DX-7, are sine wave only. The Zeroscillator also makes available sawtooth, reverse saw, triangle, pulse (with PWM), and a special set of four quadrature outputs capable of unique bi-phase wave morphing, (more on that later).

Look Ma'... No Aliasing!

FM sounds take on their vibrant life when the amount of modulation is varied dynamically. In the analog world, this requires a special VCA to regulate the depth of frequency modulation, (often called the "modulation index"). Since this is required almost universally for Linear FM patches, the Zeroscillator has this VCA built-in. We decided however, to take this feature one extra step beyond and provide you with a four-quadrant multiplier instead of a traditional two-quadrant VCA to expand your modulation possibilities into the unexplored. The output of this multiplier is available at the panel, so you get a free ring-mod function and an interesting pick-off point for self-modulation patches called Mod Out.

In addition to it's precision 10-turn tuning knob, the Zeroscillator has 1V/octave plus attenuated exponential inputs and can behave just like the VCOs you're used to. You are not forced into any specific modality and are free to use all or any subset of its 7 different modulations:

1-Exponential FM
2-Linear Through-Zero FM
3-Linear FM Dynamic Depth Modulation
4-Bi-Phasic Waveform Morphing in Quadrature
5-Pulse Width Modulation
6-Variable Sync (from none to hard synch)
7-Time Reversal

Signed Moog Minimoog Voyager Anniversary & Dotcom modular

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"This mid-size dotcom modular system is offered in excellent condition, fully working with no marks or scratches. Also included in the auction is a Moog Minimoog Voyager Anniversary Edition, signed by Bob Moog himself. I bought the Moog just before Bob Moog sadly passed away in 2005.
In addition to all the complexity offered by the dotcom system, and the classic format of the Voyager, I have customized a Moog C-351 CV expander, and made a panel to include it in the dotcom rack. The finish is every bit as professional as the rest of the system. By connecting the Voyager with the multicore cable, it's CV's, LFO's, envelopes, noise, and a comprehensive range of controllers become patchable on the front panel. I have also added extra multiples on spare panel space. The build quality of both the dotcom and the Moog is of very high standard, and of course you get that classic rich Moog sound, with a total of 5 Oscillators available.

Original Moog Minimoog Model D Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"This Mini is fully functional, and has been well used over the past forty years (I've had it for about twenty.) It has the older, more desirable oscillator card and the Moog Music label. It has recently been recapped, so all electrolytics are new and in no danger of failure! The power cord has also been changed, as the old one was dangerously frayed and crumbling. Apart from that, everything is stock. All that this synth now needs is a basic tune-up and it will be ready for the stage and the studio once again..."
