Thank you for checking out this game. The idea behind this game is to help you learn piano chords and master common chord progressions across various keys using a MIDI device. Whether you're a beginner piano or keyboard player looking to understand how to connect chords or someone who enjoys playing different pieces, composing, or improvising, Chord Nebula is here to assist you.
To use this game, you'll need a MIDI keyboard. Some mobile applications also allow you to use your phone as a virtual MIDI keyboard.
Please note that Chord Nebula is still under development, and you might encounter some issues. Your recent support and feedback have given me the motivation and enthusiasm to continue expanding this software, and I will be working on improvements soon. To stay updated on any new releases or changes, please join our mailing list.
