It’s a so-called “music tracker” software which is a specialized kind of application that emerged in the 80s for composing 8-bit-style music.

In general, it has a rather rigid structure, best suited for straightforward 4/4 melodies, where you can throw in some effects here and there. But the nice thing about that is that you’re very quick to produce good-sounding results, even if they may be simplistic.

The most recent update (which was apparently more than a year ago 😅) added a synthesizer to create your own samples more easily. You need samples to make each note play a tone, so this makes it even easier to jump into. As a result, I am having quite a bit of fun with it, again, which is why I decided to post here. 🙂

It is free and open-source (GPLv3).
