With Melody table, notes are generated according to settings determined by
the user. The upper section of the Melody table determines the difference in
pitch of successive note and the lower section determines the change or
stability of direction of that difference in pitch. If you prefer, you can
go to Examples to practice.
With melody table, frequency and direction can
be defined for eight notes within an octave.
ACS generates melodic phrases by blocks of 8 notes. The first note of each sequence is randomly selected by
ACS but the user can shape the melodic pattern of the whole with two
parameters.
Range of difference of
successive intervals
There can be 8 degrees of difference in pitch between 2 adjacent notes:
1 means that the phrase will move to the second note using the same note
pitch. 2 means that the motion will be of one whole interval note above or
below, depending on the direction set in the lower section. And so on
for the other settings. So this Table basically works excluding
half-intervals; the occurrence of half-tones is determined by the four
adjustments to chord parameters at the right of the Table, or the Dissonance
parameter in the Tune structure window; non-chord or dissonant notes is
permitted by unselecting some of the boxes.
The value of frequency probability can be from 0 to 100. For example, if 2
have a frequency 70 and 3 have a frequency 80, jumping to a third interval
above or below occurs more often than jumping to a whole note above or
below.
Direction stability or change
Plus value raises the probability of keeping the direction taken by two
adjacent notes as set in the upper section. Minus value raises the
probability of changing the direction.
The probability of direction change can be from -50 to +50. Therefore the
center means 0 or no change in difference between successive notes. Then, if
only the interval 1 is set to maximum, a monotone melody is generated by
this specific parameter.
