Space-efficient key changes

I don't think anyone cares about saving space, but...
Here's another proof-of-concept.

As great as it would be, I don't think there's any way to do this with Bxx. The only method is to copy the entire rest of the part, but replacing the repeated 1 part with the 2 part. Sorry...

Can't do it with Bxx, but you can with carefully-ordered patterns.

Put your "part 0", part 1, and part 2 (referring to your image) in separate patterns, and order them in the frame editor like that^. Pattern 0 is used twice, resulting in space saved from not storing a fourth pattern.

FamiTracker abstracts away track synchronization using frames, so you cannot find loop commands that are available in some sound engines and MML compilers.

Old versions of FamiTracker did have a track-local loop effect though, but the commands were automatically emitted by the NSF exporter, and inaccessible from the tracker. It is called ft_cmd_expand in the assembly source and can be found in the Vegavox II NSF.
