Four Voices Still Need Four Separate Wires

A video came through my feed this week of a four-voice analogue synthesizer being played by something called YOLA — a controller sending independent CV and gate per voice, so each of the instrument's four oscillators gets its own pitch, its own trigger, its own small decision, instead of sharing one keyboard's worth of information four ways. I have not put my hands on a YOLA. I don't own one, haven't patched one into my rack, and won't pretend otherwise — the demo is somebody else's work, not mine.

But the idea underneath it is one I think about every week in a very different room. MPE — MIDI Polyphonic Expression, the standard this kind of controller leans on — exists to solve a problem that is older than MIDI: a chord is not four copies of one note, it is four notes that each want to bend, swell and die on their own schedule. A piano already knows this; the dampers and hammers are mechanically independent per key. Most synthesizers, for forty years, pretended a chord was one signal wearing four hats.

CV and gate solve it the honest way, by refusing to compress four decisions into one wire. Every voice gets its own pair — pitch here, trigger there — and the polyphony becomes a wiring problem instead of a software trick layered on top of a mono brain. It is slower to build and uglier to look at than a single ribbon cable, and it is also the only version of the idea I actually trust, because I have built the ugly version myself, on a smaller scale, patching a four-voice rack where each voice's envelope answered to its own gate instead of a shared one.

The habit I am stealing from this, long before I touch whatever YOLA turns into next year, is the discipline of not letting four things agree to share one wire just because sharing is tidier on a spec sheet. In a mix the same argument runs under different names — a bus compressor pretending four vocal takes want the same attack time, a reverb return asked to flatter a verse and a chorus with one setting because routing a second felt like clutter. The tidy wire is almost always the one lying to you about how many decisions are actually being made.

Somewhere in Tokyo tonight there is a four-voice analogue box doing exactly what the video showed, patched by somebody who is not me, each oscillator answering its own gate without once checking what the others are doing. That is the only kind of polyphony I believe in — four voices, four arguments, nobody averaged.

I grew up at the bottom of the world, on the New Zealand coast, close enough to the sea that the salt got into everything, the speakers included. The radio dropped out every time the weather turned, so I learned early that sound is something you can lose. Reckon that's why I've spent my whole life chasing it. I chased it across the Pacific to Los Angeles and never quite went home: a dozen years of other people's sessions, first as the kid making coffee in a Burbank studio, now from a small room in Echo Park. I'm a producer and an engineer, but mostly I'm a bloke who can't sit still when a good record comes on. Give me a guitar with a bit of hair on it, a synth that drifts out of tune as the room warms up, a low end you feel in your chest. I want sound you could take a bite of: big, wide, a room breathing around the band. Long dinners, loud speakers, nights that don't know when to quit. Life's too bloody short for bad sound. One rule, and I don't bend it: if I haven't put a signal through it, I'm not writing about it.
