Choose a channel, select its instrument, set a duration, and press any colored pad. Each pad adds a playable note to the selected track and updates the visual score and DV text.
Choose instrument: In the Channels panel, open the Instrument menu on your channel. Choose piano, violin, guitar, or another instrument. This is all you need to set up sound; sampled audio is automatic when available.
Color Matrix: left to right changes the note; higher rows are higher/brighter octaves.
Visual editor: select a note on phone, tablet, or desktop to reveal Edit, Duplicate, Delete and timing buttons. Edit opens a dedicated dialog. Drag a block to move it; drag its right edge to change duration.
Play only: use Pad action → Play only to audition notes and chords without inserting them. Switch back to Insert into score to compose.
3D view: choose 3D Babylon.js above the score to explore your notes in 3D. Requires an internet connection on first use. Tap any block to select it and use the action bar to edit.
Live score previews: the colored DV score, traditional staff preview, and DV notation update together when you change an event.
Chords: select the Professional chord keyboard for eight qualities per piano key (major, minor, 7, maj7, m7, diminished, half-diminished, dim7). Chords insert all constituent pitches as stacked simultaneous DV notes. You can also toggle Stack Chord in other controllers.
Rests: insert a timed rest using the Rest button, or Shift-click the REST lane in the timeline.
Slides and bends: select Slide or Bend for a note, then use Edit to choose its destination note and the duration before moving. DV syntax follows the Composer family: Do4E-S-Mi4E or Do4E-B-Mi4E. Other articulation tags are prototype extensions.
Triplets: choose Q3, E3 or S3 durations, which follow the existing DV Composer / Player convention of one-third of the named note. These are retained in DV text and exports. A custom triplet duration can also be entered as an exact fraction.
Bar notation: notes are separated with semicolons within each musical box, vertical bar lines separate boxes, and @beat timing markers preserve visual gaps without introducing unwanted rests.
Melodic degrees and frequencies: choose Note names = Frequency (Hz) or Melodic degrees, with a selected tonic and musical scale; chords display their component degrees, not harmonic chord symbols. Musical-degree syntax uses e.g. 1:4Q (tonic degree in the fourth root-relative octave) and frequency tokens use 440.00HzQ.
DV Text: switch to the DV Text tab and edit tokens, then Apply DV text.
High-quality playback: sampled sound banks are used automatically where available, with built-in audio available offline. An optional Sound panel lets you switch banks or retry loading samples. These are high-quality sampled browser instruments, not desktop VST/VST3 plugins. Additional sound libraries and VST-host integration could be added in future releases.
Projects: New clears the demonstration after confirmation; Save project downloads a full JSON backup. A local draft is automatically saved to this browser and can be restored with Restore draft.
Export: save project JSON, MIDI, WAV, SVG, score HTML, or print to PDF.
Supports touch, mouse, and keyboard shortcuts. Basic synthesis works fully offline; optional sample libraries need internet. Sampled playback is available when successfully loaded. WAV exports use loaded sampled voices when available, with synthesized fallback. Pitch bends in MIDI are channel-wide, so overlapping notes may be affected together.
