Description
This example creates a list of notes (L) containing the same number
of elements as a given list of durations (I) which are derived
from an arithmetical series (A).
Patch structure
A: The arithm-ser box (A) creates an arithmetical series
from value 10 to value 200 with a step of 20.
B: The length box (B), as we have already seen, counts
the number of elements in the list coming out of arithm-ser
box (A).
C: The value you enter in this input module (C) will correspond
to the shortest duration in your rhythmic sequence( It is of course
an arbitrary number which will be scaled afterwards).
D: The value you enter in this input module (D) will correspond
to the longest duration in your rhythmic sequence.
E: The module om-scale (E) scales the values coming out
of the arithm-ser box (A) between the values entered in
inputs (C) and (D). In order to round the result we will use om-round.
There we will be sure to have integers going from 1 to 12.
F: The om* module will multiply each element of the list coming out from om-round by 250 in order to output a correct format ofdurations in milliseconds (250 representing a sixteenth note).
G: The om-quantify (G) quantifies the list of values coming
out of om-round into measures of 4/4, with a tempo of 60,
and with a maximum unit division of 8 (thirty-second-note resolution).These
a re the default values.
H: Open and edit a sequence of notes in the CHORD box (H)
(using the "order" mode). Then close the box and lock
it.
I: The create-list box (I) makes a list with the elements
you have entered in the CHORD box (H). The length of the
list is defined by the value coming out of the length box
(B).
J: The flat box (J) transforms the incoming list of lists
into a flat list (a simple list).
K: Evaluate the VOICE box (K) and open it to see the result.
Change either the values of the arithm-ser box, the values
of the inputs numbox (C) and (D) and look at the new results.
