Glissandos

General
Glissando is the fast and smooth passage between notes (much faster than arpeggio). It's usually slide of the notes. Usually modders put glissandos as sliders, or very fast double tiles. (Screenshot from Rousseau's video)

Transcribing glissandos
The best method for making glissando is using ~ operator. Usually the notes length is too short to define them by letters, like 0.10. Example: 7<(a3~g3~f3~e3~d3~c3~b2~a2~g2~f2~e2~d2~c2~b1~a1~g1~f1~e1~d1~c1)[L]>, If you don't know how to use operators click here.
