NEW FREE Online Sequencer MELODY GENERATOR 2022 [NOT CLICKBAIT] [NO VIRUS]

[pseudoname]

hi. i went back and redid that melody generator i made a while back. heres the code

Code:

function generateMelody(keySignature = 'Minor', noteVarianceFactor = 30, octave = 5, note = 1, swing = false, beatCount = 16) {
  note = clamp(note, 1, 12) | 0;
  octave = clamp(octave, 2, 7) | 0;
  while (noteVarianceFactor < 10) noteVarianceFactor += 5;
  while (beatCount < 1) beatCount += 1;

  let noteDict;
  switch (keySignature) {
    case undefined: noteDict = settings.pianoNotes; break;
    case 'Major': noteDict = settings.scales[1].slice(0, 7); break;
    case 'Minor': noteDict = settings.scales[13].slice(0, 7); break;
    default: throw new Error("That's not a real key signature. Come on, man. You're better than this. (valid key signatures are 'Minor', 'Major', or undefined)")
  }

  let midTendencyFactor = [10, 7, 4, 0, -5, -10];
  let master = 'Online Sequencer:000000:'

  function createNote(time, pitch, length, ID) {
    master += `${time} ${pitch} ${length} ${ID};`
  }

  function randomlyShiftPitch() {
    let lowerBound = -noteVarianceFactor + midTendencyFactor[octave-2];
    let higherBound = noteVarianceFactor - midTendencyFactor[octave-2];
    let offset = Math.round(
      (Math.random() * (higherBound - lowerBound) + lowerBound) / 10
    );
    note += offset;
    while (note > noteDict.length) {
      if (octave == 7) {
        note = noteDict.length;
      } else {
        note -= noteDict.length
        octave += 1
      }
    }
    while (note < 1)
      if (octave == 2) {
        note = 1
      } else {
        note += noteDict.length
        octave -= 1
      }
  }
  const quarterBased = [[0, 2], [1, 3], [0, 1, 2], [0, 2, 3], 0, 2, [0, 3], null],
    thirdBased = [0, 8/3, [0, 8/3], [0, 4/3, 8/3]],

      // 0/3 and 6/3 are present so the triplets are clearer
    ],
    riffing = !swing;

  let beatCounter = 0, riffChancemaker = 0;
  function generateBeat() {
    let beatNotes = swing ? thirdBased[(Math.random() * thirdBased.length) | 0] : quarterBased[(Math.random() * quarterBased.length) | 0]
    if (beatNotes === null) {
      ++beatCounter;
      if (Math.round(Math.random())) riffChancemaker += Math.round(Math.random())
      if (riffChancemaker == 4) generateRiff();
      return;
    };
    if (typeof beatNotes == 'object') {
      for (let x of beatNotes) {
        randomlyShiftPitch(note, octave);
        let noteLength = ((x | 0) === x) ? 1 : 2/3;
        createNote(x + (beatCounter * 4), `${noteDict[note-1]}${octave}`, noteLength, 0)

    if (riffChancemaker == 4) generateRiff();
  }

  function generateRiff() {
    if (!riffing) return;
    while (riffChancemaker > 0) {
      let beatNotes = riff[(Math.random() * riff.length) | 0];
      for (let x of beatNotes) {
        randomlyShiftPitch(note, octave)
        let noteLength = ((x | 0) === x) ? 1 : 2/3;
        createNote(x + (beatCounter * 4), `${noteDict[note-1]}${octave}`, noteLength, 0)
      }
      riffChancemaker -= 2
      beatCounter += 1
      if (riffChancemaker < 0) break
    }
  }

  while (beatCounter < beatCount) generateBeat();
  master += ':'
  return master
}

instead of python its in javascript now, so you can just go to the console in ur browser and paste this in
once you run the function, copy the output and paste it into the sequencer to hear the beautiful random melody

if you run into any issues, DM me

no issues, works as always

haha just kidding i made it betterer

Code:

function generateMelody(instr=instrument, swing=false, beatCount=16, keySignature='Minor', noteVarianceFactor=30, octave=5, note=1) {
  note = clamp(note, 1, 12) | 0;

  while (noteVarianceFactor < 10) noteVarianceFactor += 5;
  while (beatCount < 1) beatCount += 1;

  const notes = [];
  let noteDict;
  switch (keySignature) {
    case undefined: noteDict = settings.pianoNotes; break;
    case 'Major': noteDict = settings.scales[1].slice(0, 7); break;
    case 'Minor': noteDict = settings.scales[13].slice(0, 7); break;
    case 'play infinitode 2': noteDict = ['C', 'D#', 'F', 'G', 'A#']; break;
    default: throw new Error("That's not a real key signature. Come on, man. You're better than this. (valid key signatures are 'Minor', 'Major', or undefined)")
  }

      SequencerView.repaint();
  }, () => {
      for (let note of notes) song.removeNote(note);
      SequencerView.repaint();
  })
}

now it instantly inserts the new melody into the sequencer, and it supports undo
you can also make it whatever instrument you want
have fun

[Ctrl]

good shit

[tbyunomi]

I'm not familiar with using the console

How do I use it and enter commands? (Sidenote I cant used Lucent's Guide because its blocked)

[pseudoname]

you just paste the code in and then afterward you can type generateMelody() to generate a melody

[fornplakes]

oh this is the good one?

[Crumb]

Yeah it's the newer one
