Ad scan below.

"In near mint condition, with factory MIDI. Voice boards and PSU recapped, calibrated. The autotune function has been deactivated because we have calibrated the filters to be able to self-oscillate and apparently that is incompatible with the autotune check on startup, but the synth is fully tuned. Copy of user manual (in german), schematics and docs included. 220V version.


The Banana is a 6-voice polyphonic synthesizer that, in terms of design, strongly resembles the famous Oberheim OB-Xa, but it is not an OB-Xa clone. It features an OB-Xa-like voice architecture with two CEM3340 VCOs, a switchable 24dB lowpass/highpass filter based on the SSM2044 chip, and CEM3360 VCAs and CEM3310 Envelope Generators for the six voices. This provides a rich, warm analog sound that is still relevant in modern music productions. The Banana allows for sound editing with the versatile 2 ENVs (envelopes), similar to those found in the OB-Xa, making it a powerful instrument for both complex soundscapes and powerful leads and basslines.

The Banana was produced in West Germany by Electronic Engineering Hoffmann (EEH), in collaboration with Synthesizer Studio Bonn (SSB), and it is the only synthesizer ever released by EEH and distributed by SSB. In 1983, Electronic Engineering Hoffmann (EEH) completed the development of the Banana in collaboration with Synthesizer Studio Bonn (SSB), the world’s first specialized synthesizer store, located in West Germany. SSB had already made a name for itself by creating custom sequencers, including the Synthorama, which was used by Kraftwerk to control their Minimoogs on the legendary Trans-Europe Express.

Production of the Banana ran from 1983 to approximately 1985, after which the synth was discontinued. Only 100 to 300 units were made. This makes it a particularly rare model for collectors or musicians looking for a unique synth.

This model offers a unique opportunity for the serious synthesizer enthusiast or collector who is searching for a rare instrument with historical value.

Don’t miss out on the chance to own a piece of synthesizer history!"

EMS Synthi AKS - Beautiful example just serviced by EMS

via this Reverb listing

"This is an excellent original example of the highly sought-after EMS Synthi AKS. Our client has owned the instrument for over 40 years and used it primarily for home recording until approximately 1995, after which it was stored.

Following inspection, the Synthi AKS was sent to EMS for a full service, with repairs carried out where required. This recent factory-authorised servicing by EMS significantly reduces the uncertainty often associated with vintage Synthi ownership.

Serial number: 45138KS

Cosmetic Appraisal:

The instrument remains in excellent original, unmodified condition. The control surface shows only light age-related wear consistent with a Synthi AKS of this vintage. The Spartanite case presents well, with some marks from use, and the nickel catches and hinges show an expected aged patina while operating correctly. No keys are supplied for the case locks.

This EMS Synthi AKS arrived with a heavily worn set of original matrix pins. To address this, a complete new set has been purchased directly from EMS and is included in the sale.

The service by EMS covered all the critical items, including replacement of ageing power-regulation capacitors, deep cleaning, and calibration. In addition, the following work was carried out by EMS at our request:

1. VCO stabilisation modification implemented

2. All three VCO potentiometers replaced

3. Joystick potentiometer replaced

4. Full set of twenty-one new matrix pins supplied



Details of the repairs carried out by EMS are itemised in the service invoice, a copy of which will be supplied to the new owner. As the manufacturer has carried out the servicing and repairs, we are satisfied that the instrument is operating correctly and it is therefore sold with our 90-day warranty.

This Synthi AKS operates on either 240V or 110V mains supplies via the built-in voltage selector."

The Summer Constellations for Gong, VCS3 and ARP 2600


video upload by R. Reger

"The core of this piece is how the gong interacts with feedback from the VCS3 that I generate by overdriving the synth’s reverb module. If you’re a synth fan, the synth action in the first part of the piece is minimal but gets more involved in the second half."

Dave Smith / Roger Linn Tempest Drum Synthesizer Performance with Joystick


video upload by Reuben Jones

"This is the complete performance that I recorded for Alex Ball's documentary on drum synthesizers ( • A Potted History of Drum Synthesizers [posted here] ). Cheers Alex!

I never truly unlocked the Tempest until I made this video. I always found the workflow tricky and the sound hard on my ears. I'm also not huge on drum machines due to their often-fixed time signatures, perfect timing, and the fact that real drums are so much better. But like with a lot of gear, putting in the time really does reap the rewards. The sound palate is very malleable and wide. If only it could import samples!

The joystick was a bit of an afterthought. I made it for my PolyEvolver, on which it can be routed to almost any parameter using the two expression/CV pedal inputs, and by assigning breath control and foot control each to one of the many destinations. Dave Smith is THE MAN, and he put two expression pedal inputs on the Tempest as well.

Analogue Solutions Colossus Double 2024

via this Reverb listing

"This went from the crate to my humidity controlled basement. It's never been turned on, but I can turn it on and make a demo video for anyone seriously interested. I'd rather keep it in a brand-new (not-turned-on) state, though.

This is the double Colossus with the optional (additional) touch key plate and optional second oscilloscope.

The top of the slim cabinet's wood panel (the upper cabinet) has a scratch. My brother-in-law helped me move it to the basement, and his dog scratched the top panel while we were moving it.

I paid $68,000 USD (synth, additions, crates, and shipping from UK)."

Vintage 1974 Moog Minimoog Model D Analog Synthesizer SN 4019

via this eBay listing

"Up for auction/sale is a highly collectible, stunningly preserved 1974 Vintage Moog Minimoog Model D (Serial Number 4019). Manufactured during the coveted "Golden Era" at the Williamsville, NY factory, this iconic instrument is 100% vintage and features its highly desirable, rare original smooth factory wheels—proving it has skipped the typical late-70s retrofits and repair-shop modifications.

For the serious collector or professional musician, Serial #4019 represents the ultimate holy grail of analog synthesis, boasting the raw, heavy, authentic sound that defined 1970s music history.

Why Serial #4019 is Highly Collectible

Smooth Wheels: Features the original flat, smooth-edged cream wheels used briefly from 1974 to 1975 before Moog switched to ribbed wheels.

Revision 2 Oscillator Board: Contains the legendary early-70s oscillator design prized for its raw, organic, and beautifully thick analog drift (pre-dating the cleaner, highly stabilized later models).

Discrete Moog 4012 Filter: Equipped with the legendary hand-matched transistor ladder filter for that creamy, earth-shaking low end."

I was curious about the wheel history. According to AI: 1971 to Mid-1972: Early units used clear wheels.

Mid-1972 to Early 1973: Used "blocky" white wheels.

1973 to 1974: Smooth, solid white (or cream) wheels became the standard.

Late 1974 onward: Replaced by the more common grooved or ribbed "Oreo" wheels, which were also carried over to later [Minimoog Model D] reissues.

If anyone knows otherwise feel free to comment.

"This one is personal. I got my hands on a 1974 Moog Minimoog Model D — one of the most iconic synthesizers ever built — and I couldn't wait to share it with you. In this video I do an informal walkthrough of its sounds, explore its capabilities, and close with a live performance using the Elektron Digitakt. No script, no plan, just me and a 50-year-old beast of a synth.

Cherry Audio | Expressive Sound Design with Andrew Longhurst


video upload by Cherry Audio

"More expressive performance can be achieved through various technologies and techniques such as velocity, channel aftertouch (pressure), polyphonic aftertouch, and MIDI Polyphonic Expression (MPE). These features allow compatible synthesizer instruments and controllers to mimic the subtle dynamics of acoustic instruments.

In this video, musician, producer, and sound designer ‪@AndrewLonghurst‬ demonstrates his approach to expressive sound design, showcased through his collection of presets for Ensoniq ESQ-1 by Cherry Audio. He provides demonstrations of each technique using the new Expressive E Osmose CE MIDI controller and discusses his choices for setting up these advanced modulations in a preset.

These techniques can be widely applied to other Cherry Audio virtual instruments. Be sure to check the product feature listings and documentation to determine which instruments specifically support some or all of these methods. Additionally, consult your MIDI controller documentation, as compatibility for channel aftertouch, polyphonic aftertouch, and especially MPE can vary significantly in this evolving market.
