METRIC ATTACKS
(MIDI Track Component: Attack Generator variable)
The Metric Attacks function is loosely based on
current metric theories of melody.
The function works by creating one ‘pattern length’
of potential note attacks; one for each beat. The
beat attack probability combined with a value
modifier related to its Metric Position is used to
determine whether a note attack is actually
generated.
For notes which are to be generated – a syncopation
probability is generated and evaluated. ‘Syncopated’ notes have their note attack times reduced (so
they sound earlier) by a base duration unit.
For un-syncopated notes which are generated – a ‘pick-up’ notes probability is generated and if
‘picks-up’ are to be added, the number of pickups is determined and applied.
METRIC VALUES
(General)
This function returns a value based on the metric strength of
the current composition time. This function was originally
designed for use with the Attack Probability variable to
control metric ‘positions’ of generated notes. It can be
useful with other variables in cases where you want variable
values to follow the metric ‘strengths’.
The displayed value range for each bar is based on the value
range of the owner variable.
