Hi guys. It's been a long time since i've been on the forum and even longer since i've been playing with chuck. Just wondering if you could have a look at this coding for me. It's trying to get a SinOsc to play a harmonic minor scale but alas i've forgotten how to make use of arrays.
| Code: | SinOsc s => dac;
//Harmonic minor scale
261.626 =>float C1; //Had to create C1 and C2 because
293.665 =>float D; //otherwise C would have been assigned
311.127 =>float E; //to two notes an octave apart.
349.228 =>float F;
391.995 =>float G;
415.305 =>float A;
246.942=> float B;
523.251 =>float C2;
[ C1, D, E, F, G, A, B, C2 ] @=> int bassline[];
bassline[] => s.freq |
Don't laugh at it lol coz i have forgotten a lot. I handed in my project and haven't really touched chuck since and want to get back into it now.
Cheers for any help

Try this:
| Code: | SinOsc s => dac;
//Harmonic minor scale
261.626 =>float C1; //Had to create C1 and C2 because
293.665 =>float D; //otherwise C would have been assigned
311.127 =>float E; //to two notes an octave apart.
349.228 =>float F;
391.995 =>float G;
415.305 =>float A;
246.942=> float B;
523.251 =>float C2;
[ C1, D, E, F, G, A, B, C2 ] @=> float bassline[];
for (0 => int i; i <8> s.freq;
250::ms => now;
} |
I changed your array to type float, set up a for loop, indexed the array, and put in a time delay for each note.
Welcome back, and by the way you can post to the ChucK forum under DIY now. Cheers.

Unfortunatly this code doesn't work, i think it's something to do with brackets on the "for" loop at the end, i'm gonna have a tinker and if i get it to work i'll post it here

There, try that. I forgot to check the box for "Disable HTML in this post" and the forum software misinterpreted the "<" for html. This one should work fine, I tested it.

I propose some adjustments to the original patch:
| Code: | SinOsc s => dac;
//Harmonic minor scale
[261.626, 293.665, 311.127, 349.228, 391.995, 415.305, 493.884, 523.251] @=> float ScaleFreq1[];
0 => int Do;
1 => int Re;
2 => int Mi;
3 => int Fa;
4 => int So;
5 => int La;
6 => int Ti;
[Do, Re, Mi, Fa, So, La, Ti, Do + 7, So, Ti - 7, Do] @=> int bassline[];
int octave;
for (0 => int i; i < bassline.cap(); i++ )
{
0 => octave;
bassline[i] => int GetNote;
while(GetNote < 0)
{
octave--;
7 +=> GetNote;
}
while(GetNote >= 7)
{
octave++;
7 -=> GetNote;
}
ScaleFreq1[GetNote] * Math.pow(2, octave) => s.freq;
250::ms => now;
} |
this works quite the same but added some convenience.
notes can be called by Do Re Mi..
and number of tone can be added or subtracted.
for example, adding with 7 makes it jump to another octave. |
