* In live performance situations it's critical not to accidentally stop or start the sequencer. To prevent this, we've added the ability to lock the play/stop button (pressing down on the trackpad on the Vive controller, and clicking down on the thumbstick on Oculus Touch). To do so, bring the mallet head of the one controller into the play/stop button on the other controller and pull the trigger. NOTE: this replaces the earlier implementation where the same action provided another way to stop and start the sequencer.
