Membrane
Place resonance points in a continuous pitch field. Drag for glissando, snap to scale, or let drift and sequencer modes move the composition.
A sister instrument to Ephemera
Resonance
point → pitch · pad → voice · motion → phrase
Drop a point and it rings. Gather points on a membrane, spread them across a pad grid, or split them into layered keys, then shape the sound with motion, scale, and color.

Resonance is an in-browser instrument where points, pads, and layered keys become tuned voices. You don't watch a spectrum react after the fact. You shape the sound directly.
The membrane is a pitch space. The pad grid is a performance surface. Layered keys turn ranges into zones. Motion, swing, delay, color, and time-of-day all bend the same instrument instead of hiding in separate panels.
And it's your way into Dimensional: a focused instrument that can hand its shape to the larger spatial scene.
Inside the instrument
Three playable surfaces. One sound field.
Start from a continuous membrane, switch into a pad grid, or split the same voice field across layered keys.
Pad Grid
Turn Resonance into a performance grid with generated layouts, per-pad patch design, repeat controls, and a transport built for browser play.
Layered Keys
Split pitch ranges into playable layers, edit key zones, show keyboard overlays, and keep MIDI close to the surface.
Dimensional Handoff
Send a Resonance preset outward into the cosmic sequencer when the sketch wants bodies, space, gravity, and shared composition links.
Sound design
Built to be performed, not just sketched.
Patch memory, motion controls, recording, and MIDI all sit on the surface, so a sketch can become a take without leaving the browser.
Patch Library
Store voices
Soft pads, plucks, leads, wobble patches, and user patches travel between pads and sessions.
Sequencing
Motion first
Sweep, bounce, scatter, swing, accent, and humanize settings shape timing without hiding the instrument.
Recording
Capture takes
The instrument includes recording and a recordings library, so sketches can leave the canvas.
MIDI
Hardware ready
MIDI input, output, and learn affordances make the browser surface work with a real setup.
How it works
Place, tune, move.
The workflow is direct enough for a quick sketch and deep enough for a composed performance.
Pick the surface
Start with membrane, pads, or layered keys. Each surface keeps the same tuned voice field within reach.
Tune the field
Root, scale, envelopes, filter, reverb, compressor, delay, color, and time-of-day controls all support the same performance surface.
Let motion perform
Drift, sequencer modes, swing, humanize, repeats, and glissando turn static placement into a living phrase.
Ephemera family
Focused here. Spatial there.
Resonance is the playable voice engine: the place where a sound starts as touch, tuning, timing, and color. Dimensional is where that shape becomes a shared spatial scene.
The full instrument
It all runs in the browser.
No install, no account, no waiting. The membrane, pad grid, layered keys, patch library, sequencer, recording, and MIDI all open on the page. Learn the idea here, then play the real thing.

FAQ
Questions, answered.
A quick read on device support, accounts, and how Resonance fits with the wider Ephemera instrument family.
Yes. The full instrument runs in your browser with no install and no account. The $19.99 desktop app and the Ephemera bundle add offline use, session save/load, export, and VST3 hosting, but you never have to pay to make a sound.
Start with a point. Leave with a piece.
Free in your browser, no account. Place a point, tune it, and play the field. Then carry the shape into Dimensional when it wants space.
