v1.0.17

What's new in 1.0.17

Important. The "Buy LEDsplay PRO" button works again. It used to open an error page; now it opens the checkout. If you tried to buy and got stuck, please try again.

Change the key. The new Key panel in practice shifts a song up or down by semitones. The sheet music, falling notes, LED strip, hit scoring and playback all follow, and the panel suggests the easiest key.

Rearrange a song. In the same panel, switch a song between major and minor, play it as blues with swing, or give the left hand an arpeggio, Alberti or oom-pah pattern. The notes that changed are highlighted.

Listening. When you stop listening to a song, the listen menu offers Continue, which picks it up from the same spot.

Updates. Settings now shows what's in an update before you install it, and the app tells you what changed once it's done.

All changes

New

v1.0.16

What's new in 1.0.16

Connection. The app now connects to LEDsplay at whatever address you open it: the Pi's IP address or a hostname other than ledsplay.local. Before, the page opened there, but the app showed "Not connected" and nothing responded.

Practice. The pedal on the LED strip is off by default. To have the lights between keys glow when the score uses the pedal, turn on "Pedal on the LED strip" in the practice settings, under "Pedal and volume".

All changes

New

• practice: pedal on the LED strip is off by default

Fixes

• socket: connect from the page's own address, by IP or any hostname

v1.0.15

What's new in 1.0.15

Song library. Two new song sources: the LEDsplay library of public-domain pieces, with a composer filter, a featured toggle and a paged list, and a local collection that reads its own folder and takes uploads. You can upload whole folders; subfolders become categories.

MIDI songs. A MIDI file now gets sheet music and falling notes in Learn and Listen. LEDsplay turns its notes into a two-staff piano score. Scores that mark note dynamics play with those velocities.

Practice. Learn and Listen ask whether to start from the current measure or from the beginning, instead of showing a separate bar. Seeking while listening keeps playing from the measure you picked. A new setting turns the strip background off during a song.

Sound. Listening can play on the phone, tablet or computer you use the app on. You pick where to listen right under the Listen button, and a volume slider sits next to that choice. The device status shows whether the piano gets sound from the Pi.

LED strip power. In Settings you choose the power supply of the strip, and LEDsplay keeps the strip current within its budget. Raising the limit asks for confirmation. The power choice and the service restart now sit in a separate danger zone.

Effects. A released key fades into the background colour instead of going dark first. Lighting extra LEDs next to each key no longer dims and shifts the background.

Wi-Fi. The Pi reliably returns from the setup hotspot to your home Wi-Fi.

Other. The app starts in English unless you picked a language before. On a computer, settings open as a side panel. The SD card image no longer contains network details left over from the build machine.

All changes

New

• library: LEDsplay public-domain library with a composer filter, featured toggle and paged list
• library: local collection that scans its folder and accepts uploads, folder uploads with subfolders as categories
• midi: MIDI songs learn and play from a two-staff MusicXML score made from their notes
• practice: sheet music and falling notes for MIDI songs
• parser: note velocities from <note dynamics> in scores that mark them
• practice: ask 'from measure X or from the start' in Learn and Listen instead of a separate bar
• practice: seeking during listening keeps playing from the picked measure
• practice: setting to turn off the strip background during a song
• sound: play listening on this device, chosen right under the Listen button
• sound: listening volume set from the app, slider next to the sound output choice
• sound: report whether the piano gets sound from the Pi in the device status

• ui: English is the default language

Fixes

• led: key LED spread no longer dims and shifts the background

• wifi: unescape the SSID read back when removing duplicate profiles
• library: 'no internet' only when the device cannot reach the library server; library_unavailable for a missing or broken catalog
• learning: one request per replay, shared sound controls in learning settings
• learning: play again works in intervals; exercises follow the shared listening volume
• practice: learn menu keeps its measure number when listening starts
• settings: MIDI port selects confirm instead of offering a restart
• sound: play a song to a listening device when no piano MIDI output is connected
• local collection folder follows the user owning the app
• image: scrub the build Wi-Fi and machine state from SD images

v1.0.14

What's new in 1.0.14

Effects. The options of each animation are now behind a sliders button, and one animation brightness slider sits above the list.

About. The About page shows a support email as the main contact, with GitHub issues as the second option.

Updates. After a successful update the app reloads by itself, so the new version of the interface is shown right away.

Fixes. Trial sessions start again when the device first gets the correct time from the internet. If you never changed the right-hand colour, the old red default becomes orange after the update.

Installing with the script. The install script now takes about 5 minutes on a Pi Zero 2W instead of about 50. Every Python package comes as a ready-made build, with exact versions pinned, and two unused libraries were removed. The bundled demo songs are now part of the release, so a script install has them too.

All changes

New

• about: support email as the main contact, GitHub issues as the second option
• effects: animation options behind a sliders button, one animation brightness above the list
• updates: reload the app after a successful update so the new frontend loads
• release: the bundled demo songs ship in the release package
• deps: the full dependency set is pinned (constraints.txt) for the script install
• deps: music21 and numpy removed (unused), requests required explicitly

Fixes

• license: trial sessions start again when the clock first syncs
• practice: the old red right-hand default becomes orange after the update

v1.0.13

What's new in 1.0.13

This release includes everything from 1.0.12 (which was not offered as an update) plus the effects changes below.

New look. The whole app was redesigned: practice hub, song library, practice screen, effects, games and settings. A first-run welcome screen and a device status indicator in the header were added.

Practice mode that follows the score. Repeats, voltas and D.C./D.S./Coda/Fine play the way MuseScore plays them. Grace notes, trills, mordents, turns, arpeggios, fermatas, dynamics and the sustain pedal from the score are now part of practice and playback, with their own LED patterns. A new Chords setting (strict, normal or no time limit) controls how quickly the keys of a chord must go down. "Continue practice" resumes from the bar where you stopped.

Falling notes. A smoother clock and a faster renderer, ornaments, articulations and a pedal strip.

Effects. Saved gradients are now one shared list for keys, background and animations, with a few new presets out of the box. Your own gradients are kept. Animations have their own brightness slider; it starts at your current background brightness, so animations look the same after the update.

Free play. Octave zoom with a mini-map, a settings sheet and a drum kit view.

Games. Reaction Game, LED Keeper, Piano Battle and Tremolo were redesigned. LED Keeper pause now really freezes the game, and the Reaction Game shows its results on the page.

Fixes. The 14-day trial was over right after the first connection to WiFi when the system image was older than two weeks. The trial now counts from the first time the device gets the correct time from the internet. If your trial ended this way after installing the 1.0.10 or 1.0.11 image, it starts again after this update. Also many fixes to the sheet music cursor, playback of measure ranges and the WiFi setup.

Updates. The settings page no longer says "no updates" when the check failed (for example without internet), and it stops offering an update that is already installed. From the next update on, a failed update and the automatic return to the previous version are reported right away. Learning progress, statistics and the trial state are kept when updating from 1.0.11 (the old updater did not copy them).
