Design sounds with Synth

Start from a factory patch, shape the Sympose synthesizer, and direct agent-authored sound design.

Synth is Sympose’s programmable instrument for basses, leads, pads, plucks, keys, and effects. Its saved patch is the authoritative sound state, so a project can reopen and render the same settings without depending on the current preset catalog.

Start from a factory patch

Choose a factory preset from the Synth browser and audition it in your musical context. Factory patches are starting points rather than locked sounds.

After editing, the Device shows that the patch differs from its baseline. Reset to copy the original factory state back into the track.

Shape the sound

Synth exposes the primary decisions needed to build a sound, including oscillator sources, pitch and voice behavior, envelopes, filters, modulation, and supported performance controls. Secondary parameters remain available through the focused editor rather than crowding the arrangement.

Use sample-backed sources

Supported Synth patches can use curated or project-backed one-shot sources. Sympose validates required assets on reopen, playback, and export. A missing or mismatched source fails clearly instead of falling back to a different oscillator.

Ask Sympose to design a sound

Describe the role, character, and constraints:

Create a tight sub bass with a short click for definition. Keep it mono and avoid a long release.

Sympose can create or revise the complete patch and show the affected Device state. If generated source audio is required, Sympose commits one normalized one-shot directly to the chosen oscillator in a single project revision—use playback and undo like any other edit.

The agent can report the patch it created and objective processing results. It does not claim to have heard or preferred the sound unless an explicit analysis result supports that statement.

Save a result you want to reuse as a user preset.
