Korg PS-3200 Polyphonic Synthesizer SN 210231

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

via this Reverb listing

This one was listed back in 2011 and 2010.

"This PS-3200 was fully functional until about two years ago, but it has not been tested recently as I do not currently have the power cable and keyboard. (It should be possible to operate the unit by connecting a compatible power cable and installing a Kenton MIDI kit.) All internal components and parts remain original, as shown in the photos. Therefore, it is being sold as-is, with the understanding that some adjustment or servicing may be required after delivery."

First Jam with Dream Cinematic Synthesizer Solar 42N

video upload by Pipo Ferreira

"What an incredible machine. Had to capture the very first little jam with the new Elta Music Solar 42N. Just got it this week and finally got around to playing with it today. Just scratching the surface of what it can do. Can't wait to learn all its intricacies and develop some techniques with it so I can hopefully take it to a future live performance. Dream synth for me!

Also, can't wait to sample it a bunch into the Elektron Tonverk.

Stick around for future jams with it if you are interested. And, of course, thank you for watching/listening!"

Another great vintage goes Eurorack, TTA Resonator Module

video upload by Tiptop Audio

Check with dealer on the right for availability and price.

"With the Resonator , we were able to recreate one of the most legendary resonator designs of all time — and make it affordable. This module recreates the resonator section of the iconic 1975 Polymoog, now enhanced with voltage control over every parameter, selectable frequency ranges for each resonator, multiple gain stages, an emphasis CV with limiter, and a bypass switch. It is strictly analog, with no LEDs or digital circuitry that could contaminate the grounding with hiss, ensuring a pure, clean analog sound — the dreamy, resonating tones at their finest.

Originally designed as an end-of-chain effect for our polyphonic modules, the Resonator also excels with a wide range of audio sources, including samples, drums, and even full mixes. Despite its extensive feature set, the design occupies only 16HP and remains highly affordable.

A note about video sound quality:
YouTube plays compressed audio, which significantly affects sound quality. Compared to the original recording, the audio will generally sound muddier and harsher in the highs. However, it still provides a good sense of the character and tone of the demoed device.

Patch Overview for this video:
The first few scenes feature a polyphonic sound generated by Triax8 through Octopass , then through Octogain (not shown in the frame), and finally into the Resonator . From the Resonator, the signal goes into the Z5000 Multi-Effect module , with a bit of processing applied via the mix knob. The sound is output in stereo, either directly to an audio recorder or routed through the Z-DSP for extra reverb.

In the final scene, Tiptop Audio drum modules generate hi-hats and snare, which are mixed using the MIX7 module and then sent into the Resonator. The bass drum comes from the Tiptop Audio ONE sample player. Octolfo , the module on the left, provides multiple fully independent LFOs to modulate the many CV inputs available on the Resonator."
