Description
According to Wikipedia, "a for
loop is a structured control flow
statement that repeatedly runs a section of code until
a condition is satisfied." As shown in the for loop
pseudocode (right):
- a is initialized to 0.
- The 'for loop' syntax may be understood as
follows:
- The block of code within the curly braces {} is
run 3 times;
- By default, the increment i = 1.
- For each repetition of the loop, make a = a + 1
- First iteration 0 + 1 = 1;
- Second iteration 1 + 1 = 2;
- Third iteration: 2 + 1 = 3
This patcher is essentially a musical for loop. A metro
object controls the pulse, or beat. Each bang received
by the counter object increments the current
count, which is initialized at 0 on
program load. The offset (60) maps the count sequence
0, 1, 2, 3 onto the sequence 60, 61, 62, 63; i.e., it
plays the pitches C4, C#4, D4, Eb4 with velocity 90
and duration 1000. By default, the counter
object will repeat this process over and over. That
is, until the metro object is turned off via
the toggle object, this iterative process will
infinitely repeat.
