This is some audio captured while working on a music tracker with SDL2 (name undecided).

First part: Troubleshooting an unsteady tempo and playback rate for samples.

Second part: Confirmed the beats are off when playing two samples per row

Third part: I messed up the mixing function and ended up with this weird cut-up beat.

Fourth part: Finally, the damn thing works!

Fifth and sixth part: Attempts to implement something like the ProTracker EFx effect where samples are slowly inverted as they are played.

Just some MilkyTracker chiptunes.
