Name:
Sequence
Example:
import tactu5.*;
import tactu5.Tactu5SimpleSequencer;
// creating an instance of Tactu5
Tactu5 tactu5;
// creating an aggregator instance
Aggregator aggregator;
void setup() {
Tactu5Utilities tactu5utilities = new Tactu5Utilities();
// define various frequencies
float freqA = 440.000;
float freqC = tactu5utilities.noteToFreq ( T5Notes.C, 4 );
float freqE = tactu5utilities.noteToFreq ( T5Notes.E, 4 );
float freqG = tactu5utilities.noteToFreq ( T5Notes.G, 3 );
// declaring some notes
Note noteA = new Note(freqA,200,1,1,100,false);
Note noteC = new Note(freqC,200,1,1,100,false);
Note noteE = new Note(freqE,200,1,1,100,false);
Note noteG = new Note(freqG,200,1,1,100,false);
// declaring a sequence
Sequence sequence = new Sequence();
// add notes to sequence to create an arpeggio
sequence.addNote(noteA);
sequence.addNote(noteC);
sequence.addNote(noteE);
sequence.addNote(noteG);
aggregator = new Aggregator();
//add the sequence to aggregator
aggregator.addSequence(sequence);
// initializing and feed internal sequencer, boolean value inidicate if it will loop
tactu5 = new Tactu5(this,aggregator.getScore(),true);
// start sequencer
tactu5.start();
}
void draw() {
// do something
}
void noteReciver(Note n){
// now you have to send data to a synth
println(n.getFrequency());
}
void stop() {
// eliminate Tactu5 sequencer
tactu5.closeSequencer();
super.stop();
}
Description: Sequence class allows to create musical phrases or patterns with Tactu5. It's possible to pass an array of Note to the constructor or to add Note objects afterwards. This class automatically clones the Note objects passed.
Constructor syntax:
Sequence()
Sequence(Note[] inseq)
Parameters:
inseq .................Note[] an array of Note
Usage:
Web and application.
