On his Roland.uk artist page, Mike Lindup is quoted about having used a Roland MKS-20 module for a long time, plus he can be seen/heard talking about it and the background of his keyboard rig with Level 42 (at least) in the linked YouTube video:

MIKE LINDUP ON THE RD-800 "The piano is where I started, and being a long time user of the classic MKS20 and more recently the RD-300, the RD-800 has some exciting possibilities to further move the game on in terms of personalisation. I love the fact that each individual note can be adjusted for pitch, tone, attack & sustain, making it possible to go beyond the often clinical sound of other digital pianos. In addition there are lots of other quality sounds to play with and combine-it's time to play!”

"Later on I purchased a D-50, JD-800, and MKS-20 and P-330 piano modules. Roland always seemed to come out with the greatest sounding keyboards, and they’re user-friendly. They were bright enough to cover digital, but I really loved the warm analog pad and string sounds, the really signature Roland stuff," says Paul, at 6:30 in this video.

Roland MKS 20 is included in list of instruments played by Suzanne Ciani.

According to this article, Brad Buxer used a Roland MKS-20 module for the digital piano sound on "Stranger In Moscow".

Eric Persing has had a unique and influential relationship with Roland Corp for two decades. He started as a product demonstrator in 1984, showing some of Roland's first MIDI instruments. He quickly became involved in the R&D side with Roland Japan, earning the title "Chief Sound Designer", and began contributing his design ideas, real-world studio experience and sound design expertise. Persing's skills have left their mark on countless classic Roland instruments.

He is the originator of many legendary Roland sounds that have become part of the vocabulary and lexicon of musical sound. These include the Factory D-50 sounds such as Fantasia, Soundtrack and Digital Native Dance, a majority of the JV/XP/XV series Classics, all the Factory JD-800 sounds, the original Juno "Hoover" sound and thousands of others.

Here is a partial list of the Roland instruments that Eric has contributed his sound design, sampling and design consulting skills:
