In the electronic music underground, Richard D. James (aka Aphex Twin) is the ultimate mythological figure. For decades, he has fueled rumors about his process—claiming he writes his own custom sequencing software, sleeps only two hours a night, and modifies almost every piece of hardware he touches with a soldering iron.

But behind the tall tales, he does occasionally embrace commercial, off-the-shelf gear. In fact, he has directly collaborated with major manufacturers to build tools tailored to his notoriously complex specifications.

If you want to get a bit of that unpredictable, micro-engineered Aphex energy in your own setup, here are five pieces of gear that have earned the official Aphex Twin seal of approval.

1. Novation Bass Station II

The Connection: He co-designed its most famous firmware update.

For years, the Novation Bass Station II was considered a solid, reliable, but somewhat conventional analog monosynth. That completely changed when Novation released the v4.14 firmware update, introducing AFX Mode.

• How it works: Richard helped design a feature that allows you to assign a completely different synth patch to every single key on the keyboard.

• The Creative Use: Instead of just playing a standard bassline, you can turn the keyboard into an absolute playground of sound design. Pressing C1 might trigger a sub-bass kick, C#1 a metallic snare, D1 a modulating synth glitch, and D#1 an acid bleep. It transforms a simple mono-synth into a self-contained IDM drum machine.

2. Korg Monologue

The Connection: He programmed factory presets and shaped its internal engine.

When Korg was developing this compact, aggressive analog monosynth, they brought in Aphex Twin as a consultant. His mission was to ensure the synth could handle microtonality.

• Breaking the Grid: Unlike most synths that force you to play within standard Western musical scales, the Monologue allows you to create custom microtonal tunings. You can map bizarre, un-equalized frequencies between keys to create eerie, detuned melodies.

• The Preset Bonus: If you flip through the factory presets on a Korg Monologue, you will find several patches explicitly labeled and programmed by Aphex Twin himself.

3. Casio FZ-10M (or FZ-1)

The Connection: The vintage workhorse behind his early masterpieces.

While modern producers associate Aphex Twin with high-end modular rigs, his legendary early-90s era was built on cheap, unglamorous 1980s digital samplers. In early interviews, it was revealed that the Casio FZ-10M (a rackmount, 16-bit sampler) was used on roughly 80% of his early tracks.

"The Casio FZ-10M sampler was the ultimate weapon of the early Warp Records era. It gave his breakbeats their distinctive, crunchy digital bite."

The FZ-10M is beloved for its beautiful design limitations. It featured a rudimentary graphic LCD screen where you had to hand-draw waveforms, and an analog filter that smoothed out the low-bitrate digital samples, giving early AFX vocal chops and drum breaks their gritty, nostalgic warmth.

4. Elektron Analog Rytm

The Connection: A rare piece of modern gear he publicly praised.

Mr. Twin is notoriously hyper-critical of modern music technology, once stating that he rarely finds a commercial drum machine he actually likes. However, during a Rolling Stone interview, he made an exception for this Swedish hybrid powerhouse.

• The Quote: When asked if he brought instruments to his hotel room, he replied: "Yeah, I’ve got this brand spanking new Swedish digital-analog hybrid drum machine-sampler-synthesizer. It’s fking good."

• Why it fits his workflow: The Analog Rytm combines a genuine analog drum synthesizer with the ability to layer digital samples, driven by Elektron's legendary step sequencer. It allows for the hyper-detailed micro-timing, parameter locking, and frantic pattern changes that define modern Aphex live sets.

5. Alesis Quadraverb (or Midiverb II)

The Connection: The cavernous atmosphere of Selected Ambient Works.

You don’t need a multi-thousand-dollar studio reverb to replicate the vast, haunting spaces found on Selected Ambient Works 85-92. In his early days, Richard relied heavily on cheap, 1980s rackmount digital multi-effects units from Alesis.

The Quadraverb and Midiverb II are legendary for being wonderfully imperfect. Their digital microprocessors couldn't cleanly replicate a real acoustic space, resulting in a grainy, metallic, and blooming decay. When you feed a simple synthesizer track into a vintage Alesis unit and drench the signal in a 100% wet mix, it instantly morphs into that signature IDM fog.
