See note below). + + Notes in the list are inserted to the end of the list that works like a + circular buffer.The features are: + + 1) It is always possible to play an infinite legato passage in + direct order (n1_On,n2_On,n3_On,....). + + 2) Playing legato in the reverse order (n10_Off, n9_Off,,...) helps in + fast trills playing as the list memorizes 10 most recent notes. + + 3) Playing an infinite lagato passage in ascendant or descendant order, + without playing trills is always possible using the usual way like this: + First we begin with an ascendant passage, + n1On, (n2On,n1Off), (n3On,n2Off) , (n4On,n3Off), then + we continue with a descendant passage + (n3On,n4off), (n2On,n3off), (n1On,n2off), n1Off...and so on + + Each MIDI channel have a legato detector. + + Note: + Portamento is a feature independant of the legato detector. So + portamento isn't part of the lagato detector. However portamento + (when enabled) is triggered at noteOn (like legato). Like in legato + situation it is usual to have a portamento from a note 'fromkey' to another + note 'tokey'.
