Web Audio Arpeggiator

I wanted my own arpeggiator after hearing these M83 arpeggiator tracks.

• Create a tone sequence, then play that sequence relative to a key
• Save sequences to list. Uses localStorage to save over browser sessions
• Adjust multiple options
  • Attack - time tone reachs full volume
  • Hold - time tone plays within its beat
  • Release - time tone reaches 0 volume after stopped
  • Filter - cut offs frequencies
  • Resonance - increase harmonic frequencies around cutoff
  • Speed - speed of playing arpeggio
  • Shape - sound wave shape of the oscillator: square, sawtooth, triangle, & sine

Made with Web Audio API

Works well in Chrome and Firefox.

The code is a bit of a mess. I made this for fun.
