This article mentions Phil Collins using a Roland Octapad.

This article talks about what gear Queen used during The Magic Tour.

you can see Svein drumming on an Octapad Pad-8 and Pad-80 thoughout this video (8 is the right one from Svein and 80 the left one the way the back is laid out gives it away)

This Roland Newslink article mentions Mike Rutherford being an Octapad user as well as Phil Collins, using sticks to program rhythm machines and lines.

In this live video from 1985, Morris has an Octapad-8 mounted above his hi-hat. A clear shot is available at the 4:10 mark when a stage light sweeps across the device's face, reveealing the "Octapad" logo in the upper-right (distinguishing it from other iterations that would follow).

"A lot of the drum parts are played in via a Roland Octapad so that I have the sensation of hitting something. I'll set up my old kit in the new studio and get back to hitting skins again."

According to this Musician magazine article, George Michael used a Roland Octapad on the Faith album.

Mastelotto isn't shy with electronics. He used "a fair amount of samples" for composite snare sounds, including three alone for "King for a Day," played on a Roland Octopad, and the overtone of "a very ringy Ludwig similar to a tube-lug snare" sampled on an Akai S900. The drummer and his tech Paul Mitchell bent the samples with a warp function "to a note that sounded good" for each track. Tabourine-shaker, congas, tablas and other oriental percussion came from Casio FZ-1 samplers. A Yamaha RX5 drum machine crops up on the fade of "Hold Me My Daddy"; elsewhere Mastelotto used an MX8 MIDI patch bay to increase the velocity of a LinnDrum fed into a Yamaha QX2 program. An old Simmons SD55's kicks and snares are on "Chalkhills and Children" and "Poor Skeleton Steps Out." There's a Pearl SC-40 on "Cynical Days" -- "similar to a tambourine but more of a bongo" -- and "Garden of Earthly Delights," "for a low kick that bends up like a tabla." "Garden" also employs a Roland TR727 drum loop. And Mastelotto still uses sticks: Pro-Mark 5Bs or 909s, "butt-end."

In this Instagram video showing their performance on SNL, Will can be seen with a Roland Octapad Pad-8.

When Darren's not cajoling the crowd and telling them how "absolutely fuckin' marvellous" they are, he drops in samples and plays ambient fills with a collection of records and a couple of Technics SL1200s. He also reinforces the rhythm track with congas, timbale and a Roland Octapad triggering an Alesis SR16 and S1000.

"We have a Yamaha RX11 drum machine but I'm a bit disappointed with that. For a start the memory is a bit limited, and because a drum machine is used like a sketchpad, it's very frustrating if you can't get enough bars into it. We use a LinnDrum with standard chips - our producer has some alternative sound chips too - and a Roland TR707 and 727 which are really good. They're amazing for the money, and we've just got an Octapad (Roland's MIDI drum pad set) which allows you to record drum patterns through MIDI onto the QX1."
