this room for sound residency will be an exploration of tying digital connections and using them as an instrument. connexion used to be spelled with an x which shows the origin of the word: a binding or joining together. opening a network connexion creates a string of data which can and will be plucked. a work in the form of a net: strings interwoven and interconnetted. starting from short strings inside a single computer, over the two weeks this network will expand to cover the entire universe.

This is a two week residency in the Willem de Kooning Academy's Room for Sound, from 16th to 27th January 2023. I will be experimenting with networked music, in particular I plan to use some ESP32 boards and a Raspberry Pi to send and receive RTP-MIDI over LAN and hopefully WAN, and to translate this MIDI data to and from audio (via microphones, sensors, buzzers, speakers, etc). I would like to get other people involved in this process as well as getting the machines to interact: the machines could be not just musicians but also instruments.

Pseudocode

Get the computers to entrain to eachother dynamically, clap with eachother

While
    Countup++ per ms
    If(hearbeep) or (countup= random ~ 200ms)
        If(countup >40ms)
            Wait(countup ms)
            Sendbeep
            Countup=0

Day 1

Get the computers to sing

Today I am working with two Seeed Studios Xiao ESP32-C3 and some buzzers. Writing Arduino (C++) scripts for them to make beeps and also blinkenlights because they're fun.

/**
 * Singing 
 *
 * Plays predefined tones in a predefined order from a buzzer on pin D9.
 * Also flashes an LED on pin D8 just for fun.
 */
#include "Arduino.h"
// #include "pitches.h"

// Define some pitches of beeps, a basic time unit, a status
int dt1=200;
int dt2=90;
int dt3=360;
int dt4=400;
int duration=50;
int ledstatus=0;

void beep(int tone1,int length) {
  //this part switches the LED status
  if(ledstatus==0){
    digitalWrite(D8,HIGH);
    ledstatus=1;
  }else{
    digitalWrite(D8,LOW);
    ledstatus=0;
  }
  //This part pulses the buzzer.
   for (int tonecounter=1;tonecounter<=length;tonecounter=tonecounter+1){
     analogWrite(A0,127);
     delayMicroseconds(tone1);
     analogWrite(A0,0);
     delayMicroseconds(tone1);
   }
  //Or you could for more exact tones and lengths but no analog
  //tone(D9, tone1, length);
}

void setup()
{
  // initialize LED digital pin as an output.
  pinMode(D8, OUTPUT);
  pinMode(A0, OUTPUT);
}

void loop()
{
  //A sequence of buzzes
  beep(dt1,duration*2);
  beep(dt2,duration);
  beep(dt1,duration*2);
  beep(dt2,duration*2);
  beep(dt1,duration);
  beep(dt2,duration*4);
  beep(dt1,duration*2);
  beep(dt2,duration);
  beep(dt1,duration*2);
  beep(dt3,duration);
  beep(dt1,duration*2);
  beep(dt4,duration*4);
}

Someone else sending data from arduino xto ChucK
