>>2592The sample pool for tracker software was from many things. Stuff borrowed from other tracker files, recordings of real synths. recording real instruments, short waveforms, stuff sampled from other sources such as music, and sample packs people made. Especially on Amiga the st-xx sample packs that came with the first tracker in name "The Ultimate SoundTracker" were used a ton even if just for one or two sounds. There were a lot of carts on Amiga that let users record their own samples and make then into sound files for use in trackers and on PC sounds cards had inputs so you could use those instead. Future trackers even support alot of these old files plus new file formats so the sample pool is very huge. Samples literally could be anything you wanted to use back then and even now so what really matters is the user. For example of this idea I used this sample of Yuno and Miyako I made (
