Here is an excerpt from an interview with Dr. Fink and Rosie “ What is the bands using for piano squnds? Fink: I've been using'the [Roland] MKS-20. It works really. well, We, do our own patches and EQ them to taste, so they sound more realistic. On the last tour, I was using the MKS-20 and the Emax II grand piano sample. Sometimes I mixed them together; other times I used them separately, depending on what we needed. Did Prince play any keyboards in the most recent show? Fink: Yes, as a matter of fact. He did a .. whole section by himself, just playing piano and singing. A real piano? Fink: No, but it looks like one. [Pause.] I don't know if I should be announcing this. Oh, go ahead. Fink:: Well, this was my idea, actually. About three years ago, we had a real Yamaha grand. We put Barcus-Berrys and other pick-ups in there. They sounded okay, but they picked up a lot of ambient noise. And Prince used to get up on the piano and dance, so forget that. Anyway, the sound man came to me, because he didn't want to bug Prince, and said, "Matt, I got this problem with the sound in the piano. What do you think we can do?" I said, "There's this new MKS-20 thing. I think we should try that out, and put the Forte MIDI mod in the piano." So we put that in to trigger the MKS-20. I tried it out, and it sounded really good. Prince showed up for rehearsal a couple of days leter. He had no idea that we had modified anything in the piano. He sat down at the piano and started playing, not saying anything. I walked over to him and said, "So what do you think of your piano sounds" He said, "Sounds really great! What did you do?" I told him what we had done because of the ambient noise prob-lem. He said, "Wow! Good idea. Thanks a lot."”

Vangelis used a Roland MKS 20, according to this book.

"The main sound you hear is a DX7 harp sound, and the MKS20 piano module is duplicating that part. The chord parts are mainly played on the Kurzweil 1000PX and the dominant sound is bell mixed with strings, with some guitar added to give a full sound."

Wikipedia states ... "the rack form of the RD-1000, the MKS20, has been in his rack ever since, and its bright, expressive pianos and warm electric pianos are part of Elton's live sound to this day".

In the September 1987 issue of Keyboard Magazine, it is mentioned in the third column on page 31 that Danny Elfman owned a Roland MKS-20 and a Roland MKS-30 Planet S rack in his home studio. The article was authored by Bob Doerschuk and Jeff Burger.

"Robert really likes the [Roland] MKS-20 piano module, so I've stuck with that. I've got some Prophet and Ell piano samples, but piano samples never seem to work live. I do actually use a piano sample for one of the old Cure songs, 'All Cats Are Gray' [from Faith], which has this really heavy single-note piano line at the end. For that part, I use a Prophet sample, which is quite powerful in the low range. The problem, of course, is that it's so difficult to get a piano sample that sounds real across the keyboard."

"There are three sound sources", he explains. "There's an Akai S900 which has samples transferred from the Fairlight Series III, a Roland Super Jupiter and a Roland MKS20 piano module. All of those go into an Akai MIDI mixer and through two effects: a Yamaha SPX90 and an Alesis Midifex. They're all mapped by a Cooper Electronics MIDI Link, and I play them from a KX5 slung round my neck and a couple of Yamaha pedals. They put out program numbers to the MIDI link and that sends out separate program numbers to everything else. In other words I'll build up an entire patch with sound sources, a mix, effects and a stereo output, and store it. Then, when I send one program number into it from either the keyboard or from the pedal, it'll send the appropriate numbers out."

This item was used by Nils Lofgren, and sold on his official Reverb shop in 2017.

As if this isn't enough, Jones' collection of sound sources is breathtaking. Inhale deeply for an (incomplete) overview: Fairlight Series III; Yamaha TX816 rack; Akai S1000; Roland Super JX, MKS50, D50, Jupiter 8, Juno 60, D550, and MKS20 digital piano; Korg Wavestation; Prophet T8; MiniMoog; Vocoder VP330; Yamaha KX88 and TG77; and somewhere in a corner his old 808 drum machine. Still there?

In 1989, Brent Mydland was captured on stage with his PC-88, with the Roland MKS-20 and a B3 visible to his right. This setup is verified by Ryan Storm in his article "The Grateful Dead Keyboard Rigs - Yes, All of Them."
