Subject description: Close encounters melody		 Reply with quote  Mark this post and the followings unread
There are 5 notes in the close encounters alien theme:

1 - A 440.00
2 - B 493.88
3 - G 392.00
4 - G 196.00
5 - D 293.66

The melody is from memory, and I read the frequencies off an old book from my education years back.

Here is the Close Encounters song for your enjoyment:

Code:

SinOsc osc => dac;

while (true) {
    440.00 => osc.freq;
    second/2 => now;
    493.88 => osc.freq;
    second/2 => now;
    392.00 => osc.freq;
    second/2 => now;
    196.00 => osc.freq;
    second/2 => now;
    293.66 => osc.freq;
    second/2 => now;
    0.0 => osc.freq;
    second => now;
}

This one uses an array and a BlitSquare:

Code:
BlitSquare osc1 => dac;
3 => osc1.harmonics;
[440.00, 493.88, 392.00, 196.00, 293.00, 0.00] @=> float freqs[];
while (true) {
    for (int i; i<6; i++) {
        second/2 => now;
    }
    (3.0/2.0)*second => now;
}

OH, wow, I just thought of the coolest idea for this program. I'll make it accelerometer controlled. When you tilt the sensor one way it gets louder, another faster, another pitch shifted or something... could be kewl! Great stuff for the ChucK show...

Rob (Muied Lumens) in the chatroom suggested adding a Tuba feature, dropping the frequency with a ChucKian pitch shifter when the accelerometer is upside down, so here it is...
