1.2.0.3, again a very niche one: Notes are skipped if you enter song mode with `^song` instead of `^s`. Timing changes are still applied, though:
^s ^l=4 animal n1 n2 n3 ^s o k. ^song ^l=4 animal n1 n2 n3 ^s o k.
This is extremely niche and not a big deal but I thought it was kinda funny: If a lot of bass notes are doubled up with other notes in quick succession, the bass notes start fading out:
^s ^l=16 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14 ^d n10 kk14
