I think you mean the arpeggios, and those I cannot do correctly at all
arpeggios are easy, it just changes the pitch of the note as it's played
it works better with repeat (right click) depending on what kind of instrument
for instance, a short noise instrument (say, volume 15 11 8 6 4 3 2 1 0) with arpeggio -4 -2 -1 0
i mean I don't really know how to explain it properly but it's like
if you have an instrument with arpeggio -4 -2 0 then every time you play the instrument it would slide up to the note you actually put
and 4 2 0 would slide down, etc
combined with looping the arpeggio you can get some weird-sounding instruments
as for the actual songs themselves, not sure if I really like the way the triangle goes waaaay up at the end but it's fine otherwise I guess
