1. Laptop Instrument
Programming a Tune

2. Program Sections Instrument Note names Duration array Tune array
Play loop

3. Instruments The clarinet // Define the instrument
Clarinet Benny => dac; //patch the unit generator to the dac
// Wet the reed, attach the reed, set the embouchure, etc.
0.3 => Benny.reed; //reed stiffness
0.1 => Benny.noiseGain;
8.0 => Benny.vibratoFreq;
0.4 => Benny.vibratoGain;
0.2 => Benny.pressure;

4. Note Names Define pitch names based on MIDI designations
The note segment, created from the note spreadsheet

5. Duration Array Set the tempo Define an array of durations
120 => int tempo; // marching tempo
Define an array of durations
dur duration[20];

6. Duration Array (2) Set the durations based on the tempo Etc.
//quarter note duration * relative note length
(1::minute/tempo) * (4./1) => duration[1]; // whole note
(1::minute/tempo) * (4./2) => duration[2]; // half note
(1::minute/tempo) * (4./4) => duration[4]; // quarter note
Etc.

7. Tune Array
Chuck the tune as an array of pairs of integers to the tune array. Start with C major scale with half notes.
[[C4,2],[D4,2],[E4,2],[F4,2],[G4,2],[A5,2]
int Tune[][];
First integer of a pair is the MIDI note number, represented by its name.
Second integer of a pair is the index of the note duration in the duration array.

8. Play Loop Define a loop that plays each note in turn
for( 0 => int i; i < Tune.cap(); i++) {
Std.mtof(Tune[i][0]) => benny.freq; //convert MIDI note number to frequency
1.0 => benny.noteOn; //attack the note
duration[Tune[i][1]] => now;
1.0 => benny.noteOff; }

9. Play Loop – Try 2 Define a loop that plays each note in turn
Include note spacing
for( 0 => int i; i < Tune.cap(); i++) {
Std.mtof(Tune[i][0]) => benny.freq; //convert MIDI note number to frequency
1.0 => benny.noteOn; //attack the note
duration[Tune[i][1]] => now;
1.0 => benny.noteOff;
5::ms => now; //set note spacing }
