01
Designed around the gesture.
Every Quiver plugin starts from a real MPE controller - Osmose, Push 3, Seaboard, LinnStrument, Continuum - not a spec sheet.
quiver
Software that moves with your touch.
Plugins built exclusively for MPE controllers - Osmose, Push 3,
Seaboard, LinnStrument, Continuum.
MPE
Why MPE
Per-note expression deserves its own software.
MPE - MIDI Polyphonic Expression - turns every finger on your controller into its own voice. Pitch, pressure, timbre, motion: each note breathes independently. Played on hardware like the Osmose or Push 3, it feels less like programming sound and more like playing it.
Quiver makes plugins built for that gesture. Three MPE synths and three MPE effects, designed from the first line of code for per-finger expression - not retrofitted from mouse-and-knob ancestors. Without an MPE controller the catalogue still loads; with one, it finally has something to do.
MPE synth · modulation matrix
reach
Every audible parameter, under the reach of every gesture.
Two oscillators, a sub, a state-variable filter, a saturation stage - and a 13-by-4 matrix that maps your MPE expression directly onto warp, detune, drift, cutoff, resonance, drive, and the mix levels. Pressure, slide, strike, lift; each finger walks each cell from its at-rest anchor to wherever the dice rolled.
Reroll the matrix in one click. Freeze the cells you love. The deepest plugin in the catalogue.
Reach
- 13 destinations × 4 MPE sources
- Two oscillators, sub, filter, drive
- Reroll dice with per-row freeze
- Matrix-driven UI
- Every dial, MPE-played
MPE instrument · sample slicer
carve
Drop a sample. Carve it. Play it by hand.
Drop a vocal, a breakbeat, a field recording. Carve detects transients and lays one slice across each MIDI key. Pitch bends the slice, pressure swells it, sliding along the key surface scrubs the playhead inside the slice. The sample stays where you put it. Your fingers do everything else.
No sequencer, no step grid. The SAMPLR gesture, made for the MPE era.
Carve
- Drop and auto-slice
- Note picks the slice
- Pressure → amplitude
- Slide → playhead scrub
- Bend → pitch
MPE sine synth · free
string
One string. One pure tone. Played by every gesture.
One oscillator with four waveforms, a Serum-style phase bend that turns clean shapes into asymmetric ones, soft drive, ADSR, and a mono toggle. Five MPE modulation rings route your fingers into drive, bend, attack speed, chord-spread detune, and a release-velocity lift flare.
Free forever, no email gate. The easiest way to feel what MPE does to a Quiver plugin.
String
- Sine plus selectable waveforms
- Asymmetric phase bend
- Soft drive
- Every parameter MPE-driven
- Always free, full quality
MPE polyrhythmic gate
lash
Hold a chord. Lash the audio into patterns played by what you press.
Each held MPE note triggers a gate at its own rate - C2 = 1/4, C3 = 1/8, C4 = 1/16, C5 = 1/32. Chromatic semitones between are polymeter ratios. Hold a chord and three rhythms layer on top of each other, pressure-weighted across the held voices into one mix.
Per-note pressure mixes that voice in, per-note slide warps its duty cycle, per-note pitch bend shifts its phase. An LFO tool you actually play.
Lash
- Note → rhythm rate
- Pressure → mix
- Slide → gate width
- Bend → phase shift
- Polyphonic polymeters
MPE reverb
cast
Cast verb-throws by pressure. Press to bloom, release to snap.
A Schroeder reverb whose size, damping, and predelay are driven by held MPE notes. Pressure-weighted across voices, the amount knob scales how far the reverb deviates from its base settings as you play.
Note-on blooms the wet send; last note-off snaps the tail. The iconic UK garage verb-throw, played on the keys instead of automated in a clip view.
Cast
- MPE size / damping / predelay
- Pressure-weighted across voices
- Note-on bloom
- Last note-off tail snap
- Schroeder reverb engine
MPE dual filter
frame
Frame the signal between HP and LP walls, both played by gesture.
A high-pass and a low-pass in series with a drive stage between them. Pressure raises the top end, pitch bend raises the bottom end, sliding presses resonance up, velocity bumps drive on the attack. Four MPE axes, one filter shape that follows your hand.
Drop it on a vocal, a synth, a drum bus. The whole shape moves under your fingers.
Frame
- HP + drive + LP in series
- Pressure → top end
- Slide → resonance
- Velocity → drive
- Bend → bottom end
Behind Quiver
Made for hands that play.
02
MPE-native, day one.
Designed from the first line of code for per-note expression. Not retrofitted from a knob-twisting world.
03
Quiet UI, loud sound.
Soft glass, calm typography, no flashing badges. The interface gets out of the way; the music speaks.
04
Boutique, deliberately.
A small catalogue. Each plugin made deliberately - in public when it helps, in private when it doesn't.
