DonutStudio

Notes as relationships

  • Every note's frequency comes from its link chain
  • Pure ratios from the harmonic series, at any interval and any harmonic
  • Move a master note and every note linked to it retunes with it
  • Link two notes and their tuning is set automatically, with no cents to juggle by hand
  • Import Scala scales, retune the whole session live as an MTS-ESP master, and let Root Path Tune keep a progression in tune for you
  • Microtuning survives export. Per-note pitch-bend MIDI and DAWproject carry your exact frequencies into any DAW
  • Automatic per-note audio results follow the harmonic graph in Free. Pro adds detailed pitch, formant, timing, and resynthesis editing plus Vocal Synth
  • A full DAW and video editor, plus local stem separation, factory Grid patches, and bundled score-reactive visualizers in Free. Pro adds advanced authorship and specialist systems
  • 3 platforms: Windows, macOS & Linux
  • 480+ Airwindows effects included free
  • 1,300+ instruments in the in-app browser

Built for the whole piece

DonutStudio began as a way to draw tuning relationships between notes. Now it is a standalone DAW and a VST3 or CLAP plugin. MIDI and DAWproject exports keep the tuning.

16-track instrument host

Sixteen tracks, each with its own instrument and its own tuning through the harmonic graph: soundfonts/SFZ, a six-operator DX7-engine FM synth (OP-7), an analog-modeled VA synth (Sybil-16), and hosted VST3/CLAP plugins.

Modular node graph

A Bitwig-Grid-style patch editor: build instruments and effects from control, audio, and modulation nodes with any-to-any routing, and drop external plugins in as crash-isolated nodes.

Vocal synthesis

Sing a part in any tuning. DiffSinger neural singing, UTAU voicebanks, and WORLD resynthesis (beta) all follow your harmonic graph. (Pro)

HEJI score notation (beta)

A grand-staff view that auto-derives Helmholtz-Ellis just-intonation accidentals straight from your link ratios.

Media Machine: Free visualizers + Pro authoring

Use bundled music- and harmony-reactive visualizers in Free. Pro unlocks custom GLSL/ISF shader authoring, the cross-domain modulation matrix, GPU particles, raymarch scenes, and per-frame scripting.

In-app store

Install soundfont, shader, and footage packs without leaving the app. New libraries appear as the catalog grows.

Watch a link form

Link, tune, hear

Shift-click to create a link. Double-click to cycle harmonics. Move a master and every slave follows, because the frequency is the relationship.
