新版本 1.0
1.0:
• Needs Android 12 or newer, and no longer asks for the location permission
• New About screen: version, license and links to the source code
• On phones the whole top bar fits: Settings and About are icons
• Metronome: Start/Stop is next to Done, always visible on phones
• A damaged settings file no longer crashes the app; it's replaced and saving works again
• No stuck note when a MIDI keyboard is unplugged while playing
Sun Piano is an electronic piano for Android. Every sound is synthesized in real time by its own engine, so the app is small and needs no sample downloads.

Keyboard

  • All 88 keys, multitouch, with a mini-map to jump anywhere on the keyboard

  • Glissando: slide a finger across the keys to play each one

  • Loudness from where you touch a key

  • Note names as letters or Do-Re-Mi, 7 to 28 visible keys, octave buttons

  • Tablets held upright (Android 16 and newer) show two keyboards stacked



Sound

  • 8 instruments: Piano, Electric Piano, Honky-Tonk, Organ, Strings, Harpsichord, Marimba, Synth Lead

  • 24-voice polyphony, sustain pedal, stereo reverb, low-latency audio

  • Transpose and tuning (A4 from 415 to 466 Hz)



Practice and recording

  • Metronome with tempo, time signature, tap tempo and beat indicator

  • Record and play back what you play. Each recording keeps every note's instrument, even when you switch instruments in the middle, and the settings it was made with, such as the tuning

  • A Library to play, rename and delete recordings



Share and import

  • Share a recording as audio (.m4a), which plays on any phone or computer and in messaging apps

  • Share it as a standard MIDI file, with General MIDI instruments, to edit the notes in other music programs

  • Import MIDI files from other apps: all tracks, tempo changes and the sustain pedal, with their instruments matched to Sun Piano's sounds (drums are left out)



Connect a keyboard

  • USB MIDI keyboards, and Bluetooth LE MIDI keyboards found and connected from Settings (notes and sustain pedal)

  • A computer keyboard: Z to M and Q to U play two octaves, Space is the sustain pedal
