Eachparameteronthispagehastwovalues,aslistedbelow.Fortheenvelopesegments,thefirst
(upper)valueisthe durationofthesegment, andthesecondistheamplitudelevelatthe

Attack Segment Levels
Thesearethefinallevelsthateachsegmentachievesatcompletion.Thelevelsareexpressedas
