"Another one from the end of February 2024. One oscillator is set to SEQ and the other to KBD, so you hear a droning note under an 8-step sequence from the onboard sequencer. At 1:48 I start playing some notes and you can hear the portamento. Mostly this video demonstrates the filters."

"Insane. The Yamaha CS-30 is an animal. The filter, the oscillators, all those envelopes, all that modulation—it sounds amazing, wild. And it’s an ecosystem. Self contained, with its own sequencer, LFO, headphone output, keyboard; flip a switch to transpose your 8-step sequence, flip another to drone, drone, drone, flip a switch to change envelopes. But it also has external audio in to the filter, external control voltages in and out, sequencer pitch and gate out, and so on. So on! So on!

Solo leads, cellos, vocal formant and vowel, alien bells, whatever, it’s versatile.

It tracks Hz/v for all you Korg MS-10, 20, 50 folks, all you thyratron-loving Zerosum Inertia folks, Metasonix folks.

Very nice ergonomics. Good angle to the controls. Large knobs and faders.

This one has been around here for a few years, but had a problem with the keyboard glitching. It was just serviced and is now working great, plus it has been changed to operate on North American power."

Update:

SN 0152 via this listing

"Legendary and very rare 1970s Eko Ekosynth - analog Italian Monosynth.

Working but needs some attention. See attached video for full demonstration of current working condition.

Some keys sticking, drone in the background of the sound.

Capable of extremely far out sounds with the audio rate LFO assignable to multiple functions.

Synth was working perfectly up until about 3months ago (apart from the sticking keys) and has just developed the issues."

"Hohner String Synth from late 70s made by Italian company Elex who made other string synths for Farfisa, Logan and whoever else asked them to build a model. if they asked real nice.

This thing is in awesome shape and sounds like a poor man’s ARP String Ensemble/Eminent Solina. Much closer to the functionality and sound of an Elka Rhapsody 490 but I think the ensemble modulation sounds thicker. The lowest F# not working when just using cello sound. Could be a case of reseating one of the socketed ICs. Your basic divide-down synth. The power supply has been recapped and some other cap replacements. I added a mod so you can dial in or remove the ensemble modulation. Gives another sound set for some combo organ type vibrato-less sounds. Separate power supply/swell pedal.

With the power supply/vol pedal, this is kind of heavy so would prefer to meet somewhere in the Atlanta area. Of course I offer shipping as well for a flat rate.

Run this gal thru some phaser and start working on that horror movie soundtrack or Klaus Schulze-inspired kozmik voyages. Very easy to work on but you wont need to do anything to enjoy immediately."
