Greetings Friends!

A massive update of Paint Composer is nearing completion. Please test it out on the 'beta' channel if you like. All feedback is highly encouraged and welcome!

  • Complete rewrite of the audio system
    • MIDI support (drop a MIDI file into the app to load it). Tested with hundreds of MIDI files with great results.
    • MIDI continuous controls (volume, pan)
    • MIDI pitch bend support
    • SoundFont support (drop a SoundFont into the app to load it for a song)

  • Complete rewrite of the rendering system (now using WebGL)

    • Added 3d shader backgrounds that can react to audio waveforms (will eventually be completely customizable!)
    • Scrubber/Minimap to easily scroll to any position in a piece.
    • Lyrics rendering.

  • New / Updated Features

    • Note Velocities!
    • Note Durations (only with custom SoundFonts for now but will be expanded to the "classic" synth as well)
    • Time Signature UI
    • Key Signature UI (kind of busted right now but will be fixed soon)
    • Instrument Picker UI
    • Viewport Panning Tool
    • All existing songs can be loaded in the newer version. New songs save as .midi and can be easily loaded in other software. Imported songs are ~2 dB quieter and the default volume for new notes in songs in ~4 dB quieter.

  • Fixed Bugs

    • Export to .wav clipping issue fixed.
    • Eraser sound is no longer loud as heck.

  • Known Bugs

    • Key Signatures are all kinds of hecked, will be fixed before releasing to the main channel but didn't want it to hold up all the rest of these cool new features.
    • Some clicking on certain SoundFont and MIDI file combinations, will be improved over time as the root cause is isolated.
    • 2/4 Time signature has rendering glitch where start of measure jumps around.

  • Future Features

    • Customizable 3d shader backgrounds.
    • Editing pitch bend and MIDI CC parameters.
    • Editing lyrics.

Game update28 Aug 2026Paint Composer 0.6.0-pre.8Paint Composer 0.6.0-pre.8 New · Two new ways to see your song. A vertical piano roll — notes fall onto a keyboard and light the keys as they sound — and a horizontal roll with the keyboard down the left and time scrolling through a hit line.

A required module was missing from the app package; if the previous build wouldn't start, this one will. Playback fixes · Pitch bends now decode the full 14-bit value. Previously every bend read as nearly full-scale down — with a wide bend range set, whole channels could play an octave low. · Drum kits no longer stack every kit layer onto every note (p…Game update17 Aug 2026Update August 17Composer 0.6.0-pre.5 Sound engine · Instruments now have real reverb: every voice feeds a shared reverb bus, so sustained notes and releases sit in a common space instead of stopping dead. · Playback is much closer to how your soundfonts were designed to sound: velocity layers now select the right sample, and hi-hats and other exclusive-class instruments correctly cut each other off. · Stereo p…
