Using a Nano to make wild Sounds - Bytebeat

1

I found out about ByteBeat Algorithms today and this inspired me to try it out in an Arduino Nano. The resulting notes depend on the algorithm chosen. I used 2 different ones.

Here is a quick demo of a couple with some effects from the NTS-1 synth/effects unit.

I think it’s going to be fun to explore…

Hey @John136772

That is absolutely wild!

Definitely seems like something that @Pixmusix would be into.

Thanks. Yes. I think he would.

SICK MAN! :fire:
I have never heard of bytebeat algorithms.
Typing bytebeat algorithm into wikipedia get’s me to this page
Where did you learn about it? Any resources you could link me to?

I just googled some things, but the best was a page that had some simple code:

// one-line algorithmic music
// see viznut's blog http://countercomplex.blogspot.com/2011/10/algorithmic-symphonies-from-one-line-of.html
// and http://www.youtube.com/watch?v=GtQdIYUtAHg&feature=related

// ported to arduino by stimmer
// Audio out on pin 10

void setup() {
  TCCR1B = (TCCR1B & 0xf8) | 1;
  analogWrite(10, 1);
}

void putb(byte b) {
  static long m;
  long t;
  while ((t = micros()) - m < 125);
  m = t;
  OCR1B = b;
}

void loop() {
  for(long t=0;;t++)putb(
  // uncomment ONE line below
  // or try making one of your own...
  //t*((t>>12|t>>8)&63&t>>4)   // by viznut
  // ((-t&4095)*(255&t*(t&t>>13))>>12)+(127&t*(234&t>>8&t>>3)>>(3&t>>14)) // by tejeez
  // t*(t>>11&t>>8&123&t>>3)    // by tejeez
   t*((t>>9|t>>13)&25&t>>6)   // by visy
  // (t*(t>>5|t>>8))>>(t>>16)   // by tejeez
  // ((t*(t>>8|t>>9)&46&t>>8))^(t&t>>13|t>>6) // by xpansive
  // ((t&4096)?((t*(t^t%255)|(t>>4))>>1):(t>>3)|((t&8192)?t<<2:t)) // by skurk (raer's version)
  // (t>>7|t|t>>6)*10+4*(t&t>>13|t>>6) // by viznut, xpansive, varjohukka
  // t*5&(t>>7)|t*3&(t*4>>10) // by miiro
  // (t|(t>>9|t>>7))*t&(t>>11|t>>9) // by red
  // v=(v>>1)+(v>>4)+t*(((t>>16)|(t>>6))&(69&(t>>9))) // by pyryp
  // (t>>6|t|t>>(t>>16))*10+((t>>11)&7)  //by viznut
  // (t*(4|7&t>>13)>>((~t>>11)&1)&128) + ((t)*(t>>11&t>>13)*((~t>>9)&3)&127) // by stimmer
  );
  
}

This is what I used to start with.

I just connected pin 10 and ground to a speaker

Yes. Great fun. I’m looking forward to experimenting more.
