Ultra Rare Rhodes Chroma, Expander and Enabler Fully Functional and Serviced SN 21030798

via this Reverb listing

Additional SYNTH CITY Listings

"This absolute madlad is a collaboration between Rhodes, ARP and Redshift, creating one of the most crazy synthesizers we've ever had in our shop. While the Chroma is a great synthesizer on its own, the expander and enabler make it even more special/easy to use. While you don't have 32 voices of polyphony when linked, you can have 16 notes polyphony with two seperate pitches per voice. 64 weighted and velocity sensitive keys give you plenty of room for expression. With the Enabler's knob per function layout and the ultra rare Expander's extra voices give you some massive sounding pads. The expander and chroma connect with an Apple IIe interface, and the cabling needed is included with the synth. There's also a sustain pedal which we've never seen with any of our other Chromas.

Fully fuctional and just serviced by our synth tech. This is a very rare find. Shipping will be via U-Ship to ensure safe delivery. Do not miss your chance to grab this elusive machine. We most likely will not have another set like this come through."

"The Chroma Polaris was the predecessor to the classic Rhodes Chroma. Even with its heritage, the Chroma series of keyboards has seemed to resist the inflation that vintage analog synths often have. This synth gives massive sounds with the added benefit of having midi I/O. A hi-fi synth with 6 voices of analog polyphony. Creamy sounds, very lush with tons of character. Total sleeper! Wow."

Video in the listing previously posted here.

"This Rhodes Chromas is in perfect working order, sounds absolutely great, and has been thoroughly updated & reconditioned:

• CC+ Kit Installed – The original CPU board has been removed and replaced with the fabulous CC+ kit. The Chroma CC+ Kit (CPU Plus) significantly upgrades the original Rhodes Chroma synthesizer by adding essential modern features like integrated MIDI, much more program storage (200 programs in 4 banks) instead of the original's limited space, better control over parameters, and expanded MIDI functionality. It essentially modernizes the vintage keyboard, making it fully controllable via MIDI and allowing for complex patch management. It also replaces the original battery-backed memory with non-volatile RAM, eliminating the need to replace the batteries, and removing the danger of battery acid damage.

• MIDI Adapter Included – The Chroma can now send and receive MIDI. With its wooden, velocity-sensitive keyboard, it becomes a fantastic MIDI controller.

• New Power Supply Installed – The original power supply included a large, heavy transformer, and generated a lot of heat. The new switching power supply, designed in Italy specifically for the Chroma, is energy-efficient, reliable, and regulated, ensuring that the Chroma will be stable and noise-free.

• Serviced – All voice cards have had new capacitors installed. All faulty 4000-series logic chips have been replaced, along with several faulty op-amps. Faulty traces and connectors have been replaced.


All voices pass auto-tune test and play perfectly. We’ve burned in the Chroma for 8+ hours and it works perfectly and stays in tune. All keys have been removed and cleaned, and the action feels great. All key contacts have been cleaned and work correctly, with good velocity response.

Cosmetically, the Chroma has some scratches and marks from its 40+ years of use, but overall it’s quite presentable as you can see in the photos.

The Chroma includes the original flight case – however, the foam has gone bad, and has been removed. The flight case would need to be re-foamed to be used to transport the instrument.

The Chroma is available for pickup in Las Vegas, Nevada. We can also personally deliver the Chroma to the Los Angeles, Phoenix, or St. George areas for $150.

The attached video demonstrates the Chroma playing three of the factory preset sounds.

I also have a video showing all 8 voice cards (16 oscillators, 16 filters, 16 VCAs) passing auto-tune without any errors that I can send upon request."

"This Polaris 2 was fully electronically restored and is now in like new perfect working condition. And yes, of course the membrane panel that always breaks has been replaced with a brand new one so you won't have to worry about replacing it. We don't mess around here.

sn50033x

Here's what we did to this unit to make it perfect, along with some preventative stuff other sellers rarely do...because we want this unit to hopefully outlast others.

Replaced power supply electrolytic capacitors (future-proofing)
Reflowed some solder points as a preventative measure.
Cleaned unit inside and out.
Replaced membrane panel (we consider this a necessity even in the rare cases where they're fully working, as they eventually break - panel cost is $250 + installation labor, which is of course embedded in our price)
Cleaned and lubed all slide pots and levers.
Cleaned jacks.
Cleaned key contacts.
Removed original battery and replaced with new lithium battery (3v D type)
Recalibrated.
Replaced high and low output jacks.
Replaced operating system eproms with latest version 11 (originally was version 5)

This process took 11 hours of highly skilled vintage synth tech time, plus parts costs. The result is a perfectly working instrument that's ready to play, without having to pay another tech to do what we did and to wait months to years for another tech to do it."

Reminder: Minimoog Prototype Exhibit, Erik Norlander Keyboard Sale Price Drop, Mini Minimoogs & More

via The Bob Moog Foundation

Minimoog Prototype Exhibit At the Moogseum This Weekend Only!

The anticipation is almost over! We are thrilled to be hosting the Minimoog Prototype Exhibit at the Moogseum, this weekend only, in partnership with the Museum of Music Technology (MMT). The exhibit will feature four ultra rare Minimoog prototypes from 1969, 1970, and 1971, as well as a host of related artifacts from the Bob Moog Foundation Archives.

We are honored to have JoE Silva, author of The Minimoog Book: The Synthesizer That Changed Music Forever: Sounds, Stories, and Technology join us throughout the weekend of the exhibit. He'll be on hand to delve into the history of the Minimoog with exhibit attendees and sign books in the Moogseum store.

We're excited to share a new addition to the exhibit. MMT will be bringing Minimoog serial number 1016 (the sixteenth Minimoog ever produced out of 12,269 units), which was purchased in 1971 by none other than David VanKoevering, the marketing genius behind the early Minimoog sales. David's Minimoog will be available for exhibit attendees to play and explore. Come get you hands on this incredible piece of synthesizer history!

Finally, be sure to take advantage of the morning tours with our executive director, Michelle Moog-Koussa. Michelle will be delving into Minimoog history as it is conveyed through the main gallery of the Moogseum. She doesn't give tours often, so take advantage of this opportunity. The tours are available for a small fee for any exhibit attendee.

"This circuit board came in with one of the many Rhodes Chromas we have bought, restored and resold (we’re finishing another at the moment which we will list soon). It appears to be part of a rare chroma apple ii computer interface that allowed the apple ii computer with sequencing and patch editing software to control a Rhodes Chroma. The Rhodes Chroma website, which is probably the best vintage synth support website we’ve ever come across, has an article on this interface. You can find it by googling rhodes chroma apple computer card. It appears as though there were other components to this interface that we didn’t get with it (converter box, software and possibly more), and we don’t have an apple II computer, so we haven’t tested this item and are selling it as-is as a collectors item, or for parts to possibly get a full system working (with no guarantees)."

"I finally agreed to make a video showing my synthesizer studio. I'm NOT a collector, so you'll see the instruments I've used for over four decades to do my work. It's also my space for composing. In this deep dive studio tour, I walk you through every corner of my space, showing how everything’s connected for performing, recording, and creative flow.

You’ll see icons like the 'Plantasia' Moog Modular IIIc, Synclavier II, Rhodes Chroma with Expander & Enabler, Oberheim Four Voice, Elka Synthex, Roland Jupiter 8, Sequential Circuits Prophet-5, ARP 2600s, Korg MS modular synths, some classic Minimoog — plus a few modern synths I’ve added as I look to the future. Alongside the synths are vintage drum machines, string machines, and rare electric keyboards including a 1973 Fender Rhodes Suitcase and Hohner Clavinet/Pianet Duo.

We'll also explore racks of outboard gear, vocoder units, tape echoes, and a vast array of my custom guitar pedal options, efx pedal boards and studio effects racks that make this room endlessly inspiring. I'll also reveal how my entire studio is designed for instant creativity, featuring 48 channels of synth drivers and stage boxes, so any synth can be patched and recorded on the fly."

This unit is in excellent condition and includes key upgrades: a MIDI retrofit, the Sterooping programmer for hands-on control, and a rugged, custom-built, almost-new ATA flight case for transport and storage. The Chroma has been tested and is performing as expected.

Key Features:

16 analog voices with single or dual oscillator assignability
Velocity-sensitive weighted keyboard
Extensive modulation options with assignable routings
Unique filter architecture with variable state filters
Includes the Sterooping programmer for tactile, real-time control
MIDI upgrade installed for modern integration

One of the rarest and most collectible instruments of the early digital/analog crossover era, the Chroma has been used by artists such as Joe Zawinul, Herbie Hancock, and Eddie Jobson. With these modern upgrades, it remains a powerful and expressive studio centerpiece.

30% of proceeds support the Bob Moog Foundation, preserving and celebrating the legacy of electronic music."
