A music composition tool for everyone, from aspiring composers to professional musicians!

NEW: import MIDI files and edit them!

You can write complete songs including song sections and 4 instruments (drums, bass, guitar and piano). You can even change the sound of the samples by recording or synthesizing your own. When you're done you can save it to your library, export it to a MIDI file or a WAV/.MP4 file and read the sheet music back as PDF (only for KitKat devices and up) or as a PNG; to share with a printer, yourself or your friends!

Includes:
- A 5-octave keyboard
- A 6-string Guitar (right and left-handed)
- A 5-string Bass Guitar (right and left-handed)
- A Standard Drum Kit (right and left-handed)
- A 5th custom instrument (with keyboard controls) to support other instrument sounds
- A comprehensive set of tools to transcribe drum, (bass-)guitar and keyboard loops:
* Free Play mode to record notes your playing on the on-screen instrument. Supports MIDI over USB.
* Write Notes mode to use the on-screen instrument to key in the notes. Supports MIDI over USB.
* Sheet Editor mode to visually edit your sheet music (piano and drums only)
* Dictate mode to record notes your playing from an actual instrument (piano only)
- A comprehensive set of tools to transcribe keyboard and guitar rhythm sections:
* look up chords from a very comprehensive database by key
* derive the chords from a base key, a heptatonic scale and the chord progression
* detect chord by manually tapping or recording the notes.
- Playback Midi mode to play back your song as a midi or any other midi file from your SD card. If a MIDI device is connected over USB, it will also be played here.
- Track editing to change the structure of your song (verse, chorus, coda etc.), the time signature or the key signature
- Custom samples recorder (you can record them via the built-in microphone and edit them in the Instruments tool)
- Basic sound synthesis (VCO, LFO, Low pass filter, high pass filter, attack)
- A library to save all your songs to. You can also import .mid files into your library, with all features (editing, custom sounds, sheet music and MIDI over USB OTG) enabled!
- support for MIDI devices over USB OTG (channels, programs and percussion)! You can use your MIDI instrument to enter notes and play it back! Note: On devices before Android Marshmallow, this is based on an open source library. Save your song often as some stability issues have been seen.
