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 No ads, no tracking, no internet access.
