Working towards our first prototype. Beads now turn on and off with touch, and grow and shrink in time with a global metronome. When the metronome tick reaches an active bead, a very simple synth (RNBuiltinSynthesizer) plays a tone. Finally, pinch gestures (or button presses) will let you increment or decrement the number of beads (down to 2 or up to 16)
The tempo slider goes to 480 now, as opposed to 240, which still felt a little slow.
