Arpeggiator

Generates a note sequence from a given scale.

import { registerAllWorklets, ArpType, ArpScale } from "synthlet";
 
const audioContext = await registerAllWorklets(new AudioContext());
const clock = Clock(audioContext, { bpm: 120 });
const arp = Arp(audioContext, {
  trigger: clock,
  type: ArpType.Random,
  scale: ArpScale.Major,
  octaves: 2,
});
 
const mono = MonoSynth(audioContext, {
  trigger: clock,
  frequency: arp,
});
