The engines

Nine engines in one patch

Every engine is a full sound source. Run them side by side, route them into each other and mix them however you like.

Classic

Two analog-style oscillators with a little drift and hard sync.

Wavetable

Two wavetable oscillators with smooth morphing between frames.

FM

Six-operator FM with the classic algorithms and feedback.

Additive

Up to 512 partials, each with its own envelope skew.

Phase-Distortion

The old phase-distortion trick, plus wavefolding and phase sweeps.

Granular

Grain clouds with spread and stereo drift.

Noise

Pink, blue and crackle noise with color filters.

Resonator

Physical models with tension, damping and material settings.

External-In

Feed in live audio and use it as an FM source.

Sketch

From a few words to a playable patch

01YOU TYPE

Describe it

Say it the way you would to a friend: ‘underwater’, ‘dusty keys’, ‘a bass that growls’.

02SKETCH BUILDS

It picks the settings

Sketch chooses engines, envelopes, filters and effects to match, then names the patch.

03YOU PLAY

Then it’s yours

It’s a normal patch. Tweak any knob, save it, and share it if you want to.

Scope
