"For sale is a 1984 Oberheim DMX with memory expansion running 3.2. I got this from the original owner where it had been collecting dust for almost 30 years. I addressed the cosmetic issues including refinishing the walnut sides with a Tung oil and varnish mixture and cleaned every nook and cranny of dust. I recapped all of the main electrolytic capacitors on the the main board and control board. Removed any components exhibiting corrosion from battery leakage including several IC sockets and chips. Any faulty chips were replaced by examples identical to the original equipment down to the manufacturer and year (not that it makes any difference). The screen was replaced preemptively to ensure years of use. After completing all the service steps in my abilities, I sent it to Electrongate/Paul White for the final debugging. He supplied some new buttons, battery, lid thumbscrews and sorted the last of the gremlins. It's now about as good as they come. The perfect platform for someone looking to add MIDI."

"This scarce and unique piece of German ingenuity and (over?) engineering has been tested to the best of our ability. Due to its unique architecture (i.e. - confusing layout, features, and programming), we can only vouch 100% for complete function of the screen, back lights, buttons, faders, and sounds/voices, etc.

We've included a video link of the actual unit for sale below.

It has a fat, punchy sound with a ton of retro character and a few unique and quirky voices. Once in a while we think there's a faint intermittent 'phantom' background noise?

The "SPEED" fader works but is missing the knob. Also, a handful of scratches, nicks, and abrasions are present on all surfaces - nothing serious. The power cable is safe and stable but has areas of electrical tape along its length - we're not sure why. Probably not splits or exposed wire but we did not remove the tape to find out.

Hard to find programming overlay included."

Xaoc introducing Oradea and Arad | Superbooth 2025


video upload by Thomann Synthesizers

"XAOC launched Oradea and its expander, Arad. The Oradea is an analog quad resonator featuring four bandpass filters designed to process and generate sounds while maintaining exceptionally high resonance and Q values. The emphasis was on creating a resonator effective for "pinging" without self-resonating, ensuring audible pings even at high frequencies. Each channel of Oradea hosts individual controls for frequency, peaking, and volume, which can be modulated via CV inputs."

Redshift 6 - Multitimbral Sound Demo


video upload by Supercritical Synthesizers

"Supercritical is thrilled to unveil multitimbrality for the Redshift 6 — a powerful new feature that makes the Redshift 6 more versatile than ever.

With six-part multitimbrality, the Redshift 6 can now assign its voices in multiple ways: split across keyboard zones for traditional polyphonic setups, layered to play rich, combined textures, or used as six independent one voice parts. Thanks to its paraphonic architecture, those one voice parts can still be played as full chords.

The update also unlocks the Redshift 6’s two auxiliary outputs, allowing individual timbral parts to be routed separately for more flexible mixing and sound design.

You can try the multitimbral Redshift 6 yourself at Superbooth 2025 — visit us at Bungalowdorf B020 in Berlin.

The multitimbral beta firmware is available now on the Supercritical Discord for all Redshift 6 users."
