Future Retro Revolution very rare version

via this Reverb listing
"This is a very rare silver Revolution rev2 limited to i think 9 made. Hand signed & numbered by the creator of Future Retro himself, Jered Flickinger & it was sold exclusively through Nova Musik at the time. Additionally, this specific one was previously owned by Chicago House DJ Derek Carter, a certificate of authenticity is included in the sale. As for the synth itself, the resonance, cutoff & volume pots are a little bit scratchy sounding & probably need a good contact cleaning at best or replacement at worst. Everything else functions perfectly..."

Yamaha QX1 – The MIDI Mothership - Digital Sequence Recorder
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"The Yamaha QX1 is one of the most advanced and rare digital sequencers from the early 1980s, designed for professional studio use.
It features eight independent MIDI tracks, precise timing, and an exceptionally stable clock, making it a benchmark in early MIDI sequencing. Even today, it is valued for its reliability and straightforward, hands-on workflow.
The unit has passed all standard system tests, including a fully functional floppy drive.
Very good cosmetic condition: one small dent on the front panel (see photos) and a few minor scratches.
The display glass and screen are perfect, as are the keyboard and keypad.
Internally clean, with capacitors in excellent condition and very limited use over time.
Includes two floppy disks as a bonus.
A rare, well-preserved, and fully working piece of gear."

Tre Modular - Replicant RM Demo
video upload by Tre Modular
"Replicant RM is a ring modulator based on the legendary Yamaha CS80. At its core is the same analog architecture that gave the CS-80 its character. We’ve built it around the MC1496 IC, a modern alternative to the original uA796 used in CS80.
Just like the original, Replicant RM includes its own dedicated VCO. It offers both sine and square waveforms. Sine delivers a clean, pure tone that defined the CS80’s ring mod sound. Square adds grit and harmonic complexity. The oscillator features two speed modes and a dedicated output.
We’ve also included a built-in Attack/Decay envelope generator, another key part of the CS-80’s ring mod section. It can be gated or looped, and has two speed modes for shaping everything from bell-like tones to rhythmic pulses. The envelope also features two speed modes and a dedicated output.
If you want That sound that`s part of what made CS80 legendary, now you can have it.
