Talked about in a recent interview with SoundonSound.

In the credit of the track Hey Ma, says "Justin Vernon - Matrix 6, Guitar."

"The actually brassy sounds were Oberheim Matrix 6."

"...for the past year i've been really happy with stacking a matrix 1000, matrix 6r and dsi ob-6. requires a lot more programming but the sound is almost palpable."

In this video posted to Rolling Stone Australia’s Instagram account, in which Dayglow is performing, a Matrix 6 can be seen on the bottom level of his synth stand.

"Equipment used in this song: Korg Polysix, Poly 61 (through a SansAmp GT2), Mono/Poly, Micro-preset M500; Roland TR-808, Jomox AirBase99, Juno 60, Alpha Juno 1&2; Touched-by-sound DRM1, Oberheim Matrix 6R, Yamaha RM1x (only for MIDI sequencing), Behringer DDX3216, Lexicon MPX500, as well as a midi patchbay and additional preamps for my mixer. Cameras: Canon HF100 (x2) and HF200."

THE SET UP:

They use a variety of keyboards but the mainstays are a Yamaha KX88master Yamaha DX7 Emulator 111 Oberheim Matrix synths and Akai S900 but particularly Roland's D50 and Juno 60.

Enya: "The Juno is one of our favorites. We had intended to replace its parts with better sounds but we couldn't find better substitutes so we left them in. It's not always possible to have all the sounds I want for a song at the time of composing .I'd usually start with the D50. But most often, sounds suggest parts and the ones I use then are usually used on the final recording. Like on Storms in Africa... that arpeggiated line on the Juno 60 was the basis of the piece."

In this interview conducted in 1997, Rudy provides a current gear list.

In a user-uploaded photo on Johannesschmoelling's website, Johannes Schmölling is shown using the Oberheim Matrix 6 synthesizer.

"I do almost all of my music work out of my studio at home. Ok, here goes: I use a pair of Adats, a Soundcraft Ghost for mixing, a bunch of outboard Symetrix and Lexicon processors for dynamics and effects, and an Eventide Ultraharmonizer DSP4000 for pre/post processing and vocal effects. For keyboards I use a mix of older and newer stuff. I have an old Prophet 5, a Casio FZ-1, a Roland MKS-50 with a programmer and an Oberheim Matrix 6. For newer gear, the Roland JP-8000, MC303, and the Novation BassStation are nice for creating new sounds quickly. I also have a little Korg 01/wR with a software programmer that can be coaxed into making some fat sounds (no analog filter tho). I'm pretty religious about not using presets, so I really favor the more programmable synths.

A lot of the recording and arrangement happens inside a PC; I run Logic Audio 2.5 for digital recording, post-processing and midi arrangement. I use an Audiomedia III card for digital transfers to and from a Tascam DA-30 dat. For guitar I use my trusty Les Paul through a Marshall half-stack, with an Oberheim Echoplex on the fx loop. "
