mozzmo VCO 1V/oct

[HOFFMAN Raphaël]

Hello,

Here is a little sketch to use with "mozzmo", it plays correct notes on 5 octaves (with a vc keyboard or sequencer).

It include : 

5 wave forms : sine, tri, saw, square, noise.  

cv entry.

range setting : you can choose the referencial octave then you can cover all the octave (5v simultaneously).

 

I joined a file to this message with the arduino files.

Feel free to test it, suggest improvements or post code's improvements.

Hi Raphaël,

I've copied all the code into one but It gives almost no sound

I needed to update return (int)sig<<6; for HIFI mode

btw I think you can only do this with the same length table (2048 or 8192)

void chooseWave()

{

  waveNumber = map(mozziAnalogRead(pot2),0,1023, 5, 0);

  switch (waveNumber)

  {

    case 0:

      mainVCO.setTable(SIN2048_DATA);

      break;

     case 1:

      mainVCO.setTable(TRIANGLE2048_DATA);

      break;

    case 2:

      mainVCO.setTable(SAW2048_DATA);

      break;

    case 3:

      mainVCO.setTable(SMOOTHSQUARE8192_DATA);

      break;

    case 4:

      //noise.setTable(WHITENOISE8192_DATA);

      break;

  }

  

}

so you can't mix both 

I read this somewhere but can't find it (anyone to confirm ?)

Also changing wave with the pot are not easy

why don't you just do :

void updateControl()

{

chooseOctave();

chooseWave();

controlPitch();

}

Cheers,

Oh sorry, I believe I make a saving error (i ahd two VCO sketches opened) just befor compress and upload it.

I update my code and repost it really sorry.

Here is a sketch that work for me, differents lenght oscilllator are not mixed and it include comment that explain how ot works.
