Scribble - Drummer

This is a sample created with Scribbletune patterns using this script:

const scribble = require('scribbletune');

const funkyDrummer = {
  kick: 'x-x---x---x--x-R',
  snare: '----x--x-[xR]-xx--[xR]',
  ch: 'xxxxxx[xR]-xxxxx-x[x[RR]]',
  oh: '-------[xR]-----x-R',
};

for (const p in funkyDrummer) {
  scribble.midi(
    scribble.clip({
      pattern: funkyDrummer[p].repeat(4), // Repeat the pattern to get 4 bars
      notes: 'c4',
      subdiv: '16n',
    }),
    'funkyDrummer_' + p + '.mid' // Give a name to your MIDI file
  );
}

Running this script produced 4 MIDI files that were imported into Ableton Live and rendered with few drum samples. Please visit scribbletune.com for more information on how you can create such patterns with JavaScript!
