“On a modern score, a huge amount of the emotional weight doesn’t come from the melody,” J Scott Rakozy tells us.
“Sometimes, it comes from under the melody—the de-tuned drone, the granular shimmer, the texture that makes you uneasy before you know why. And for years, that meant layering tons and tons of different variations of pads to get that sound… But today, we’re looking at a synth that can do it all with a single patch.”
In the walkthrough video above, the acclaimed composer and sound designer dives deep into Phoenix, the new hybrid synthesizer from Spitfire Audio and BT. Watch along to hear his insights as he demos the synth in the DAW, and read highlights below.
Feel free to use the table of contents below to navigate to a specific section.
What you’ll learn:
Who is BT?
Brian Wayne Transeau, better known as BT, is a legendary producer, DJ, composer, and audio engineer who has spent 30 years navigating the space between the orchestra and the machine. He’s worked alongside everyone from Tiësto and Azealia Banks to *NSYNC and Britney Spears, and is widely known for his film score work on the Fast & Furious franchise. His album This Binary Universe put a 110-piece orchestra inside a glitch record written for 5.1 surround, and he’s often credited for inventing stutter editing—a rhythmic technique that became its own language, and one that makes its mark on Phoenix.
Phoenix represents BT’s third synth with Spitfire Audio, following Phobos and Polaris.
A guide to Spitfire Audio’s Phoenix
Phoenix features over 500 presets, six synthesis engines, 37 effects, and full MPE support. But, these numbers alone don’t explain why it matters to a composer—below is a look at what’s actually going on inside it.
Six synthesis engines inside every note
Phoenix isn’t six synths layered on top of each other. Rather, every single voice and every note you play runs through the following six synthesis engines at once, on one shared architecture and one signal path, all talking to each other:
- Wavetable / spectral: The evolving, breathing tonal core of Phoenix.
- FM: Ideal for bells, glass, metallic tones, aggressive textures, and complex harmonic content.
- Sampler: BT’s private archive and some of Spitfire’s strangest source material.
- FM transient: A dedicated two-operator FM engine that designs the attack of every note.
- Subharmonic generator: Lower-octave tone generation that adds body, size, and weight.
- Complex noise oscillator: Shaped, filtered, moving noise for air, breath, bow hair, hiss, and grit.
Cross-modulation and cross-synthesis
What makes Spitfire Audio’s Phoenix genuinely unique is that these engines are all actively modulating each other. BT describes it as “true cross-synthesis”—for composers, the practical result is that one patch can deliver tone, attack, low end, and air all at once, moving as a single instrument.
Stereo from the ground up
Most synths are mono at heart, with one signal generated and then widened at the output with chorus or some other spread. Meanwhile, Phoenix is stereo from the ground up—every voice has two independent synthesis chains, one for the left channel and one for the right. The result is a pad that surrounds the listener rather than sitting on the speakers, without collapsing into an out-of-phase mess.
Phase warping and the 3D render
Phoenix’s stereo wavetable engine does deep spectral warping. Phase warping changes how the oscillator reads through the waveform, speeding it up, slowing it down, and folding or mirroring parts of the cycle so the shape changes before the sound comes out.
All of this is visible in real time through a 3D render that draws the actual waveform being synthesized as it happens. It’s visually striking, but it’s also genuinely useful for understanding what’s happening to the wave as you push things further.
Six operators and 34 algorithms
Phoenix’s FM engine is a full six-operator design with 34 algorithms. Each operator is an oscillator; some are carriers (what you hear), and others are modulators (what bends the frequency to create new harmonics). The algorithm is the wiring diagram, defining what modulates what. Change the algorithm, and the six operators act like a completely different instrument.
Any sample can be an operator, and six operators times eight unison voices gives 48 oscillators stacked inside a single key press—all stereo, with full MPE. On an MPE controller, every finger gets its own expression, allowing your FM stack to swell, bend, brighten, or do whatever your keys do, all independently.
Primitives and the source recordings
BT built Phoenix around a concept called primitives—raw, unpolished source material designed to be pulled apart and re-imagined into something new. The sampler draws from BT’s 30-year private collection alongside curated selections from Spitfire’s most unusual sources: harsh brass flutter, quarter-tone clusters, sul tasto string textures, arctic sounds, and more.
The sampler has its own transient and noise engines, and the sample runs through everything else in Phoenix. An organic recording becomes something that still feels human, but could never come out of a real orchestra, and that zone is exactly where modern scores live.
Meta sequencers and the modulation matrix
Phoenix’s modulation system is built with the continuous movement of sound design for picture in mind:
- Meta sequencers: Eight sequencers that are also simultaneously envelopes—each has four drawable stages with sections that can loop or play forward and backward.
- Random generators: Four random generators with 636 hand-made rhythm patterns for controlling predictability and keeping long cues from sounding like looped instruments.
- Modulation matrix: An unlimited matrix where sources feed synth engines, effects, and anything else.
The arpeggiator
Most arpeggiators play the same pattern every bar, but Phoenix’s arpeggiator rewrites itself with every pass, built on BT’s stutter edit-esque rhythmic language. Under the hood, there are two sequences per patch, each with its own probability; four stages of 128 hand-drawn steps are combined with per-stage play probability and eight scale modes that keep things musical.
The result never loops the same line twice, which is a significant advantage for underscore work, where a four-minute tension cue with a subtly evolving pulse can sound composed rather than copy-pasted.
37 effects
Phoenix’s 37 effects are all bespoke and studio-quality; each could arguably ship as its own product. Every effect has its own dedicated interface, and the modulation matrix can reach into all of them. The range spans from shimmering granular reverbs to lo-fi vinyl emulation.
Studio-quality presets
Last but not least, BT and Spitfire have built an extensive preset library that functions as a learning tool as much as a starting point. Pulling up a preset and reverse-engineering the signal path—tracing what’s going into what and why—is one of the most effective ways to understand what Phoenix is truly capable of.
