Trackers are a type of music sequencing software dating back to 80s era of home computers. Many trackers focus specifically on one type of sound card or chip, while modern programs such as Furnace incorporate free mixing and matching of different sampling and synthesis techniques.
Sheet music reads from left to right, with staves for each instrument and lines/spaces for each note.
Trackers scroll from top to bottom, with a single note input per column (with programming and instrument design, the one note limit isn't firm).
Working with trackers is part music, part programming, and part puzzle-solving. Whereas with typical music engraving software there are few to no restrictions on quantity and type of note that can be placed, trackers produce their sounds with a mixture of function generators, algorithms, and memory limits. Figuring out how to program instruments and simplify complex compositions into compatible form is where trackers' unique challenge comes in.
I am currently working on a video tutorial series for producing chiptune music targeted towards the skill level I had upon starting in 2022 (minimal). I plan for it to cover literally all steps from initially appraising a song to creating thumbnails, producing the video, and promoting the release. Tutorials and script writing are a growth area for me, so progress is slow but steady.
