Thanks!
If it helps, I started out using Famitracker for chiptune and learned primarily from these tutorials: https://youtube.com/playlist?list=PLW08UHPY2AEoWhZJVfaE4tUF9jpso8KI0. A lot of the basics are similar between different tracker programs, so I found this info useful in Deflemask, which is what I now use for chiptune (mainly because it supports Sega Genesis sound). Or you might prefer more modern software that isn't tracker-based, which is probably a different story!
