Looping software for the web

TODOs

• Apply changes to state to audio scheduler at the start of each loop (configurable length)

• Animate cursor on each loop

• Move audio processing to worker thread as much as possible

• hotkeys? number of loop followed by beat number (with hotkey for cancel in case of mistakes)

• Trigger stuff with MIDI input (keyboard or sample pad)
