Jen Synx 508, 5-voice Analog Polyphonic Synthesizer

via this Reverb listing
You can find demos of the Jen Synx 508 in additional posts here.
"Jen Synx 508, a extremely rare analog synthesizer, aimed at a collector who can get it working properly. Aesthetically, it's almost perfect, but it has some functional issues that need fixing:
- The sequencer seems to work, but we don't know exactly how to program it.
- Some buttons (hold, memory...) take a while to respond keeping it pressed. As it seems its not a problem of the switches, may be a factory bug.
- Envelope calibration can be improved in some voices.
- Resonance seems unstable, probably is a calibration issue as we're not sure if the filter is supposed to self-oscillate in this synth, but we calibrated it as if it were supposed to.
- The Phaser/Ensemble/Chorus effects are a little noisy, but we think it may be another factory bug as the BBDs are ok.
We haven't found a user manual, but we do have schematics drawn by an Italian technician. It's believed that the Synx 508 never reached full production, mainly due to the sequencer problems that couldn't be resolved with firmware updates. Apparently, the processor used was quite slow, which caused most of the mentioned issues.
8 banks and 8 sound presets per bank. Each voice card comes with a CEM3310 ADSR Envelope, a CEM3320 24dB/Oct 4-pole Multipass filter, and a CEM3360 Dual VCA. There are 5 voice cards, expandable to 8 if you can find spares.
New battery, almost completely recapped, new potentiometers installed, etc."

Kawai Q-80EX | One of the best 80s sequencers that nobody talks about
video upload by Espen Kraft
"The Kawai Q-80EX midi sequencer from 1989.
An absolute beast of a sequencer yet nobody seems to know it exist or what it can do.
How does it compare to two cherished competitors of the time?
Check out the TG100 plugin here: https://www.martinic.com/tg100-reverb
Big thanks to Anders E. Jensen for letting me have his Q-80EX for almost a decade.

Mylar Melodies Random8 Review
video upload by Molten Music Technology
"In collaboration with Befaco, Mylar Melodies has forged an 8-channel random CV generator called the Random8. From the starting point of random voltages you can scale, offset, time divide, quantize, slew, loop, evolve and save it all as a preset. I do a deep dive into what's going on and have a lovely time in the presence of so much fabulous voltage."
