Your instruments, effects, and routes

Choose the sound. Patch the signal.

Load OP-7, Sybil-16, SoundFonts, SFZ libraries, or your own VST3 and CLAP plug-ins. Then route audio, MIDI, and modulation across the session without leaving the project.

DonutStudio arrangement with the Sybil-16 synth, instrument browser, and a hosted FabFilter Pro-Q 3 VST3 effect open
Included on every track

Open the project and the sound comes back.

Load a built-in instrument or a hosted VST3/CLAP device, add effects, and save the chain with the project. Add-ons give you more instruments and let you patch beyond a single track.

Built-in Synths

FM precision and analog movement, built in.

Move between six-operator FM and a modulation-rich virtual-analog instrument while keeping every track inside the same project and tuning system.

Included with DonutStudio Free
Inside the workflow

FM, virtual analog, and sampled instruments in one browser

Move between OP-7, Sybil-16, SoundFont, and SFZ sounds while the track keeps its notes, tuning, and project role.

Search across sources

The browser keeps bank, library, and instrument identity visible while filtering.

Editors stay connected

Built-in synth editors open for the selected track and update the authoritative engine.

Tuned at playback

Every instrument follows the harmonic relationships in the piano roll.

Vocal Synth

Write the singer as part of the arrangement.

Type lyrics onto notes, shape expression, and render DiffSinger or UTAU voices that follow the same tuning relationships as the rest of the piece.

Available with Pro
Inside the workflow

Lyrics become a performed, tuned voice

Write lyrics on notes, inspect phonemes, shape vibrato and transitions, then render a local singing engine into the arrangement.

  1. WriteNotes + lyrics + phonemes
  2. PerformVibrato · glide · expression
  3. RenderDiffSinger · UTAU · resynthesis

Per-note performance

Vibrato depth, period, fades, portamento, and expression remain editable per note.

Local generation

Installed voices render on the machine and publish progress back to the track.

The singer follows the graph

Rendered pitch is derived from the same harmonic relationships as the instruments.
