Changelog

• Time resolution (settings drawer): “Standard (480)” uses this site’s finer ruler and is mainly for exporting to something other than the game (MIDI, MP3, video); “Match the game (96)” follows the game’s own note-value arithmetic, which suits non-standard note values and pasting into the game. Switching reloads the page; your score is kept, the undo history is cleared
• Non-standard note lengths: the toolbar tells you whether this score has any, with two buttons — Restore standard durations turns them back into standard lengths, Use game timing sets the resolution to the game’s 96
• Non-standard length compression (the third option in the optimiser): compression that recomputes with the game’s time resolution. Not one note changes in the game, but non-standard lengths are harder to read and the roll and playback on the site drift — to see it accurately on the site, switch the resolution to 96
• The “notes to deal with” list: scans the whole piece for lengths that cannot be written and notes outside the instrument’s range, listing which score, which track and which bar, a page at a time; Go jumps straight there. The entry point is the red line in the roll toolbar
• 3D mixing per score: the concentric circles at the end of the instrument row, or press S. Place each instrument in space — the spatial effect only comes through on headphones

• Piano-roll shortcuts: 0 for select-only, 1–7 for the note length (64th included), . for the dot, Ctrl+A to select the whole track, Ctrl+D to copy the selection on after itself, Delete to turn notes into rests, +／- for velocity. While dragging, the arrow keys nudge, and with Shift it is a whole octave or a whole bar
• Score tab shortcuts: [／] change the instrument, M mutes, H shows or hides the score on the roll, and adding Shift means “this one only”. M is for your ears, H for your eyes
• You can see what you are about to draw: the label at the left of the toolbar now shows real note symbols (six lengths × with or without a dot, 13 in all). In select-only mode it is a dashed box
• Instruments in use (settings drawer): set the default instrument for new scores, and hide the instruments you rarely use from the instrument dropdown

• Gayageum (@28) and Bass (@29) added: pick them from the instrument dropdown
• New built-in sound bank: the file grew from 29 MB to 37 MB. If you use the site offline it is downloaded once more — the offline sound bank in the settings drawer handles that itself
• Range extended to o8: the roll has four more rows at the top and the highest note is o8d+. Scores that wrote o8 used to be clamped back to o7b and are now read as written — the four notes of the game’s top octave are back

• Make MP4 video: turn a score into a piano waterfall video — notes falling from the top, splashing effects as they land on the keyboard. The button sits in the export area of the file box, under “Mixdown MP3 export”
• Pick the look: 12 note styles, 9 landing effects (plus “None”), and a 30-colour palette
• 16:9 landscape, with the resolution chosen by device (1080p on a computer, 720p on phones and tablets)
• Spatial mix: tick it and the result is audible as a 3D space on headphones; arrange where each score sits, on the same layout the mixdown MP3 export uses

• Time signatures and meter changes: bar lines, inserting and deleting bars, and import/export all follow the actual time signature
• Section marks: tell them apart, jump to them and edit them on the roll and the horizontal scrollbar
• Inserting and deleting bars across the whole piece: every score, time signature and section mark moves together
• Score recognition import from images and PDFs

• Percussion roll: on a score whose instrument is Drum set, the piano roll switches to a layout built for drums
• Notes become a shape at the moment of the hit plus a thin line for the length
• Dragging up or down swaps the drum, not the pitch; the empty rows in between are skipped automatically
• Not a single character of the MML changes — all that changes is which row a note is drawn on. Turn it off in the settings to go back to the ordinary piano roll

• Local file library: your work is stored in the browser (IndexedDB) and survives closing the tab
• Cloud saves: sign in and it is kept on your account, so another device picks it up
• Save manager: create, replace, delete, rename
• Ctrl+S to save quickly
• Several scores can be packed into one zip and taken away together

• Mixdown MP3 export: 16 tabs mixed into one MP3, to share the finished piece directly
• Zoom: Ctrl+wheel, the toolbar +/- buttons, and pinch on a phone (one axis at a time)
• Mobile layout: switching tabs no longer steals focus, the toolbar folds away when the soft keyboard appears, the divider can be dragged on short screens
• Better note lengths when capturing percussion
• Fixed formatting problems in MML import and export

• Touch rebuilt: a new note is drawn by dragging (the pen lands when you let go), and a long press picks a note up to move it
• Virtual joysticks: two sticks to pan the roll on a phone
• Selection fine-tuning mode for phones
• Context menus completed (two menus, opened by long press on touch)
• Four quick buttons on every tab: mute, solo, show or hide, view one / view all
• Playback shortcuts now cover the keyboard media keys; auditioning has its own channel, so the keys work during playback too

This version replaced the whole score model: one tab = one player complete score, instead of one tab per track.

• One score holds 4 parts (melody / harmony 1 / harmony 2 / vocal), and switches between an instrumental and a vocal score
• Up to 16 players together (the tab limit went 15 → 16)
• Three panes on one axis: the piano roll, the four-part text and the timeline all move together
• Note context menu: copy, paste, insert time, delete time
• Playback shortcuts: space to play and pause, arrow keys to move
• Velocity shortcuts, and a quick jump to the MML text
• Bar marks, adjustable cell width and height, mute all / hide all
• Stronger MIDI capture: percussion split out, and the drum kit split by limb
• .mid export: one MTrk per tab, with the drum kit on GM channel 10
• Fixes: long rest parsing, notes vanishing while dragged, irregular line wrapping, MIDI triplet capture

• MML syntax colouring: notes, octaves and lengths each get their own colour in the text pane
• Fixed how Ctrl multi-select was detected

• Four languages: Traditional Chinese, English, Japanese and Korean, with the URL prefixes /en/ /ja/ /ko/
• Dialogs for adjusting tempo and volume
• Three guide pages went live

• Smart capture: MIDI comes in already split into tracks, with instruments assigned
• Merging scores: two scores stacked into one

• MML compression: shortens a score automatically so it fits the character limit in the game
• Added the "autosave" switch
• Start and end lines: play only one span, copy only one span
• Multi-select notes
• Illegal characters highlighted: characters the game will not read are marked in the editor first

• Google sign-in
• File import: external MML files can be read in
• File export: what you have written can be saved out as a file
• MML formatting fixes (line breaks and indentation are easier to read)
