An instrument of resonance, not of notes.
Eight resonators trade energy through a delay network and lose a
little on every pass. Your hands decide where it collects.

What it is
Free
Free, and no part of it is a trial.
Nothing stored
Close the tab and the state is gone. Nine channels go to your
DAW and it remembers for you.
Open
The source is open, and the schematic is published on release
day, not on request.
See exactly how it works
No claim here that isn't in the code. The signal diagram, the
filter topology, the coupling maths and the four prime delay
lengths, all published, not withheld.
Read the schematic
The six controls
Essence
How hard each resonator is driven towards singing on its own.
Origin
The fundamental everything else is derived from.
Element
What the resonators appear to be made of.
Harmonic
How the eight are spaced against the fundamental.
Form
The shape the sound takes in time.
Gestalt
How much the eight behave as one body. It changes what the
other five mean.
The refusals
No presets.
Costs you the ability to return to yesterday's patch.
Nothing stored in the app.
Close the tab and the state is gone.
No account.
No sign-in, no email, no waitlist, not ever.
No analytics.
There is no counter, so we will never know how many of you there are.
No menus.
If it will not fit on the surface, it does not go in.
No tutorial.
Nobody explains a cello in an overlay.
No undo.
Playing is not editing.
No scale lock.
No quantise, no snap, no A=440.
No tier.
No price, no pro, no donation prompt while you are playing.
No claims we cannot show you the code for.
No neutrality where taking a side is free.
Routing
Browsers expose one output device at a time. Multi-channel means a
driver you install, and this says so plainly rather than pretend
it is one click.
Device
a virtual audio device: BlackHole, VB-CABLE, PipeWire, JACK
Clock
WebMIDI, either direction
Disk
a WAV streamed straight to a file you chose
It takes about an hour before you stop fighting it. That hour is
the instrument.
