MIDI Four Chords

لعب على الحبال الأربعة (IV-السادس-IV وتقدم 50 في) على MIDI.

Plays the Four Chords, used in the I-V-vi-IV progression and the 50s progression, which appears frequently in popular music.

This project is inspired by 4chord MIDI, a hardware device which does the same thing. It is based on android-midisuite's MidiKeyboard.

This software requires Android Marshmallow (6.0) or later, and MIDI support on the device.

This software outputs MIDI using Android's MIDI APIs, and requires a synthesiser (not included!) to be able to listen to it. You could use MidiSynthExample, Volcano Mobile FluidSynth, or an external synth if you connect your device to a USB-MIDI compatible device.
