Thom Yorke uses the Elektron Octatrack DPS-1, as detailed on the King of Gear Tumblr page.

Flume's Elektron Octatrack DPS1 Sampler can be seen in this Instagram photo of some of his gear.

"The Elektron Machinedrum, Elektron Octatrack and the [Roland] Jupiter-6 are my favourite hardware machines."

"...right now, also, one of my favorites. Because it's basically any kind of sampler where you put in all your sounds, or you put in loops, or even longer pieces of music. And you can real-time chop them up in here. It's very intuitive. There's a lot of randomness I like about it. This also - similar to the Monomachine - you have 8 tracks where on each track you can program one sequence... it has different FX sections as well, the first which is the most important is the pitching, but also you can choose the start point of the sample. So you can basically choose where the signal should start from the whole audio file. And you can move around, most of the time a lot of cool things happen."

"The Elektron stuff is always on and always getting some action, particulary the Octatrack wich is (...) probably one of the most revolutionary instruments of the last 20 years. (...) I've never been a sampling guy, and the Octatrack changed the way I approach sampling. Even the simplest sound bite can be transformed into a song."

Richard Devine has the Elektron Octatrack on the floor of his Euro rack modular synth corner of his North Carolina-based studio. An image of it can be seen in the video (8:55).

The Octatrack is an 8 track performance sampler and features the following:

“I do love the Octatrack. I’m not a big fan of using a laptop on stage myself. I’m not opposed to it, I just never felt like I could figure out a way of doing it where I felt like I was still performing or that there was a flexibility to it. I know Daniel from Oneohtrix and, talking to him, he’s found a way to achieve that, but I haven’t really sorted it yet.

So, the Octatracks are essentially my way of having Ableton in a box if you deal with it a specific way. I’m basically taking stems of the studio recording over seven of the tracks, using the eighth as a master channel. Typically I’ll take drums, bass, weird percussion stuff, weird sound stuff and maybe a main melodic component so I know everything’s set up with that template.

There are two Octatracks, both of which contain the exact same information on the card and I kind of mix from one song to the next. Some nights I do it better than others but it’s essentially DJing the stems of the record," says Panda Bear, in this article.
