A music tracker and some other stuff written in Yabal for the Astro-8
_ (Underscore key) - Play/Pause music

, (comma key) - Decrease speed of music
. (period key) - Increase speed of music
(all arrow keys) - Move cursor up down left or right
Move cursor in any direction and track. then type a letter or number to place a note. writing a 0 will erase a note. Notes are represented as numbers between 0 and 32, but to take up less space in the tracker the numbers after 9 use letters a-v, which is a base 32 number system. These numbers are then converted to frequencies using this chart: https://sam-astro.github.io/Astro8-Computer/docs/Architecture/Expansion%20Ports.html#conversion-table
