The editor was developed as built-in editor for Music Boy 3D game. But it's not locked to the game in any place and can be used for any other game or multimedia project.
It's possible to load audio and record the rhythm as it is done in modern music sequencers. The number of instruments is unlimited.
The editor produces MBOY file in the end which is a JSON file and can be easily consumed by any application. The audio file is not included to MBOY file.
It supports MP3, OGG and WAV audio formats.
