MURMUR

Eight engines in one synth.

Classic analog, wavetable, FM, additive, phase distortion, granular, noise and physical resonators. Stack them in one patch, route anything to anything, and run the result through ten built-in effects.

The engines

Each engine is a full sound source. Layer up to eight of them in one patch.

CLSENGINE

Classic Analog

Multi-wave oscillators with a little analog drift, the way old hardware wanders.

WTENGINE

Wavetable

Wavetable oscillator with 256-frame morphing and its own spectral filters.

FMENGINE

FM Synthesis

Four-operator FM with feedback envelopes. Bells, keys, growls.

ADDENGINE

Additive Harmonic

Up to 512 partials you can shape as you play, with odd/even balance.

PHSENGINE

Phase Distortion

Phase shaping that gives you resonant sweeps without a filter.

GRNENGINE

Granular Stream

Chops samples into grain clouds. Control pitch spread and spray.

NSEENGINE

Noise / Crackle

Pink and white noise, dust, rain and tape crackle.

RESENGINE

Resonator Block

Strings, membranes and struck materials, built from comb-filter resonators.

Imagine: start from words

Sometimes you can hear the sound but can’t find the knobs. Type what you hear, and Imagine builds a starting patch from the real engines and effects. It uses an AI model to pick the settings. What you get back is a normal patch you can tweak, save and share.

  • Chooses engines, envelopes, filters and effects to match your words
  • Every result is a normal patch, so every knob is still yours
  • Imagined patches start private. You decide what to share
  • One Koin per imagined patch
An example

You type

“Thick sub bass that slowly morphs, with some tube grit”

You get

Slow Tar

Wavetable and Classic engines, a slow LFO on the wavetable position, and the Saturator at 65% on a macro.

Example routing

LFO 1 → Wavetable MorphBIPOLAR (+74%)
ENV 2 → Cutoff FrequencyBIPOLAR (+74%)
MOD 3 → FM Pitch Operator BBIPOLAR (+74%)
SOURCES: 12
DESTINATIONS: ANY PARAMETER

Modulation

Drag a source onto any parameter in any engine. Every route has a bipolar depth, so you can push a sweep up or down by exactly as much as you want.

  • 12 sources, including multi-stage envelopes and LFOs
  • Bipolar depth on every route
  • MIDI learn and MPE support

Ten effects built in

Enough to finish a sound without reaching for another plugin.

Saturator

Tube-style saturation for warmth and grit.

Chorus

Wide stereo chorus in the style of bucket-brigade circuits.

Tape

Wow, flutter, hiss and a softened top end.

Mood Filter

Resonant acid lowpass that syncs to your host tempo.

Freq Shift

Frequency shifter, from subtle width to clangy metal.

Fractal

Bitcrushing and foldback for when it needs to get ugly.

Reverb

Algorithmic reverb, from small plates to huge halls.

EQ

Four-band parametric EQ with a spectrum display.

Compressor

Clean VCA compressor with a sidechain input.

Limiter

Brickwall limiter that keeps transients intact.

Built to play live

Tuned to stay responsive in a busy session, with latency low enough to play from a keyboard.

8

Engines at once

Stack every engine in a single patch.

32

Voices

Big chords, with every voice running its own engine chain.

< 4ms

Engine latency

Low enough to play live.

64-bit

Internal processing

Plenty of headroom before anything clips.
