Compose, produce, and publish — in one studio.
A professional notation editor, a multitrack DAW, and a mixing console — fused with a private, encrypted network to share what you make.
Notation studio
Engrave full scores — staves, tab, drums, lyrics, and tempo maps.
Multitrack DAW
Arrange audio and MIDI across up to 64 tracks with a real mixer.
Release & read
Ship music, albums, sheet music, books, and video to a built-in library.
Private network
Message, call, and stream — end-to-end encrypted by default.
Compose & notate
Write it the way you hear it.
A complete notation editor — from a lead sheet to a full grand-staff arrangement — with the marks performers actually read.
- Full engraving — multiple staves, grand staff, guitar tab, and drum notation.
- Marks & expression — articulations, dynamics, ornaments, slurs, ties, and barlines.
- Lyrics, chords & a tempo map — words under the staff, chord symbols above, and tempo changes across the piece.
- Transpose & quantize — diatonic and chromatic, with concert / written-pitch views.
- Compose on your phone — a notation-first touch editor that round-trips to the desktop studio.
Produce & mix
A full DAW and a real console.
Arrange, edit, and mix a whole session — audio and instruments together — then bounce it to a finished track.
- Up to 64 tracks — an arrangement timeline with trim, split, crossfade, and shaped fades.
- Piano roll & instruments — sampled acoustic piano plus synth and drum voices, with gapless looping.
- Automation, humanize & swing — draw volume curves and expression, modulation, sustain, and pitch-bend lanes.
- Mixing console — 3-band EQ, pan, reverb, faders with VU / peak meters, mute / solo, and a master DIM.
Record & play in
Get ideas down fast.
Play parts in from the keys you already have, and capture takes in real time.
- Musical Typing — play notes straight from your computer keyboard.
- Real-time recording — roll the transport and capture what you play, with optional quantize-on-stop.
- Hardware MIDI — connect a keyboard for step-time entry and recording, where your device supports it.
