Rhodes Chroma Vintage Analog Synthesizer w/ CC+

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

via this auction

"Up for sale is a fully working, fully upgraded Rhodes Chroma, without doubt one of the best polyphonic analog synths ever made. This is a fantastic sounding synth that has huge flexibility in terms of voice and filter configurations. It can be used as an 8-voice synth with two oscillators per voice, or with 16 single oscillator voices. The 16 filters (one for each oscillator) can also be arranged in serial or parallel configurations, in either high or low-pass modes. An analog ring-modular, sync and FM are also available. I've owned a Matrix-12 and the Andromeda, and this just blows those out of the water in terms of pure sound quality, plain and simple. The sound is best described as 3-D and organic which is the result of discrete rather than chip-based oscillators.

Better yet, this is one of THE best supported vintage polysynths out there. There's a huge user community and loads of newly developed options and this particular model includes all of them, including:

-CC+ (a new CPU that adds midi control over every parameter)

-Upgraded, new power supply (the old one is usually the source of failures on these)

-Polyphonic aftertouch: this allows you to control aftertouch per KEY, like on the CS-80, rather than across the whole keyboard as is the norm on most synths with aftertouch.

Functionally, this is virtually flawless: autotune works every time and the synth tunes up very quickly after a brief warm-up. (It actually turns on and is basically ready to play, but I have to put in the caveat that it needs to warm up since studio temperatures can always change). Also, ALL of the voice cards have just had their capacitors replaced, and the output EQ board has also just been serviced by one of the master synth techs out there, John Leimseider. All keys trigger reliably, but it is worth noting that several will not trigger if played very lightly and until you have applied full [pressure. This is not due to dirty contacts, but the nature/spacing of the metal contacts internally. I believe this can be adjusted, but I was not prepared to attempt this. If playing normally, this shouldn't be noticed..."

Rhodes/ARP Chroma 2103 Analog Keyboard Synthesizer

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

via this auction

"Vintage early 80's analog synth Rhodes Chroma Model 2103 #0567, the last significant project by ARP synthesizers. 16 channel programmable polyphonic synth with true dynamic keyboard feel (velocity and after-touch sensitive full-size wooden keys). This keyboard is in great physical condition. It has seen no use since it was purchased from the music store 35 yrs ago. The keyboard is close to being physically immaculate, clean in and out, not a nick on it. Original wood looks great and all keys like new and snap right back responsively with no marks on them at all. Keyboard has the original power supply which still works. That being said, electronics like to be on and 35 years of no use results in some necessary internal service. When switched on the fan runs but LED's aren't lighting up. This will need to be checked out by a technician but I've already discussed with and been estimated to completely upgrade to full working condition the following, where necessary, new power supply, new CPU board, any issues with analog voices etc. somewhere in the range of $1000-$2000. Pro re-furbed units have been recently selling by known brokers in the $8000-$9000 range and there is currently one selling on eBay for ($9699)."

"To say the Chroma sounds superb is an understatement. The flexibility, rawness, charm, and feel of the Chroma is magical. I purchased this in 2013 and had it repaired and upgraded with the new PSU and CPU (CC+).

Everything works and has been tested the night of this listing. That said, I can only sell the Chroma as-is. It’s enormous, heavy, and the voice cards can be finicky when moved in transit."
