COLAPSO isn’t a synth you program. It’s one you explore. Pick an element, excite it, and see what it gives back — tones that sit between instrument and phenomenon, and never quite settle twice.
A synth that plays the periodic table
Pick an element from the periodic table and its measured emission spectrum becomes the timbre. Every partial is a real spectral line, cross-checked against the NIST Atomic Spectra Database and transposed down into hearing range, with its own level and its own decay. One control, Observation, trades time against pitch like the uncertainty principle: a broadband click at one end, a pure, stable tone at the other, and a whole territory in between.
Inside COLAPSO:
- 22 elements to build each oscillator from, and Mix to morph into a second one
- Observation and Planck: the uncertainty principle as a playable control
- 3 oscillators per voice, up to 16 partials each
- Partials that decay at their own measured rates, so the sound keeps evolving while you hold a note
- Temperature, Field and Absorption to heat the spectrum, split it and flip it into noise
- 9 filter circuits, 4 drawable LFOs and 4 drawable envelopes
- Up to 8 voices in Poly, Mono or Unison
- Over 200 factory presets
The short version
COLAPSO is an additive synthesizer whose harmonic content is measured. Pick an element and its emission lines become the partials of the note you play.
COLAPSO is a sonic interpretation of the uncertainty principle. A sound can be precise in time or precise in pitch, never both — and one control, Observation, decides which. Whatever you don’t measure, you hear blur.
What it is
- An additive synth with a laboratory for an oscillator.
- Sixteen partials per voice, per oscillator, their frequencies taken from an element’s real spectral lines and their decay times from the measured transition probabilities.
What it does
- Trades time against frequency, out loud.
- Observation moves along the Gabor limit — the signal-processing twin of the uncertainty principle.
- Planck sets how blurry the universe is at its best.
Why it’s different
- The physics is the instrument, not the theme.
- Lifetimes, level populations, ionisation and cascade are what the controls actually move, and they behave the way the phenomena do.
