Richard David James appears to be an extensive collector of expensive rare gear. On the Syro album packaging, the gear list shows us that he owns not one, but three instances of the Korg PS-3300 Polyphonic Synthesizer. It is important to note that this is not an ordinary synth: Sources claim that only 20 to 50 units have been produced. This synthesizer is not only the biggest, but one of the most expensive pieces of rare analog gear ever. Of course, to some people, this list can be somewhat of a fraud, based on the various rumours that surround the Aphex Twin's history. The rumours that he owns a tank, a submarine, has a bank converted to a house, at the age of 11 made a Sinclair ZX Spectrum produce sound after tweaking it and many others has led many to believe that the artist is a compulsive liar. Especially in some interviews. Some of these were confirmed, some weren't. The Analord series itself has its own mythology of what was used to produce it. But after all, this is for each one to decide. Despite having a few mistakes according to Richard himself on a 2014 interview with Dave Noyze, the Syro album packaging is an official product, and it is one's choice to decide wether he/she believes what is written there.

In this review of Keith Emerson's 1981 album "Honky", Background Magazine notes where the album was recorded and what musical gear Emerson used on it:

"Honky was recorded in the Bahamas and 'honky' is what the local children called Keith while he was there! The pictures inside the booklet show that Emerson's stay there was primarily a holiday, so this album was recorded in a relaxed, carefree spirit. For this record Emerson used the following instruments: Yamaha CP30, MiniMoog, Hammond C3, Korg 3100 & 3300, Steinway concert grand model D, Yamaha grand and a vocoder."

Kraftwerk's Korg PS-3300 is now owned by Karl Bartos.

Presser Gábor used the Korg PS-3300 Polyphonic Synthesizer during the recording of the "Electromantic" LP, as detailed in the article "Gabor 'Pici' Presser" from Electronics & Music Maker (April 1983).

One of the many synthesizers used by Satoh in Medical Sugar Bank's self-titled album.
