Besides being mentioned on the Syro gear list, Richard gives more details about this piece of gear with a comment about microtunings left on his SoundCloud page (user18081971). Comment can be found on his uploaded track called "Love 7": "with the chroma, i just use midi for sysex midi tuning dumps to get them in, bit more tricky getting them out but doable."

It's actually a Rhodes Chroma. Used on some of the Blur albums and on the first few Gorillaz albums for some synth leads, brass, and stuff like that.

I had some MIDI instruments on Logic for the track 'Café D'Athens' — a marimba part and a vibraphone part — and I sent the MIDI into the Chroma Polaris. It's just an amazing synth. Very intuitive and it felt like an important synth for us to use on this record.

Most recent post (at this moment) shows the acquisition of a rare Rhodes Chroma (without Polaris).

In the YouTube video "I Love Quincy," Herbie Hancock can be seen using the Fender Rhodes Chroma synthesizer. Additionally, the liner notes of his album "Future Shock" and other albums mention this instrument, highlighting its significance in his work.

A Rhodes Chroma is shown and described at 0:30 in this Studio Tour by MusicTech. Ulrich says about the synth "It has typically an app sound in the sense that it has a very aggressive - very present mid-range - I find it very useful for sort of elements that need to cut through in the mix, like melodies or sequences that need to be very present."

"Very rich-sounding instrument with polyphonic aftertouch, velocity sensitivity, and immense programming capabilities. Almost like a modular synth in a programmable box."

"Zawinul did not stop at the Wurlitzer and Fender Rhodes electric pianos he used in the 1960s. By the late 1960s he was extending his sonic palette with effects like phase shifters, Echoplexes, wah-wahs and ring modulators, and when synthesizers came on the market he was among the first to buy one (the EMS Putney). The list of synthesizers he has used since then — among them the ARP 2600, Rhodes Chroma, Oberheim Four-voice and Eight-voice, ARP Quadra, Sequential Prophet 5 and Prophet T8, Korg Trident, Oberheim Xpander, Korg VC10 vocoder, Emu Emulator, Casio CZ101, Korg DW8000, DSS1, DSM1 and M1 — reads like a synth museum's treasure list."

At his home studio (dubbed “50” for the street address where he lives), Price would often access his bank of vintage synths — including a Moog Polymoog, Korg MS-20, Roland SH-09 and a rare Rhodes Chroma — to add textures to a demo track or to supplement the Clavia Nord Lead 3 that Flowers uses as his main synth.

In Anthony Marinelli's studio tour video titled "My Synth Studio Revealed | Studio Tour 2025," the ARP Rhodes Chroma is prominently featured at the 58:06 mark, confirming its use by the artist.

Jimmy Waldo, a renowned keyboardist, uses the Fender Rhodes Chroma. This is confirmed by a quote from Keyboard Magazine, November 1984, where Waldo states, "an unbelievable amount of bottom, but I've found that a lot of that low end isn't really usable when you're playing in a 10000 seater or on a record."
