* Use 16-bit audio output * More audio tweaks (mute on startup, working volume control) * Treat the rotary input as a scroll wheel (works now) To-dos: * Better global keymap (incorporate touchscreen) * Turn on plugins and define the approximately eight bajillion keymaps * Still have some audible pops when we turn on, need to figure out why * Default Cabbiev2 comes off as rather crappy on this device ...I don't know how much work I will do on this thing, as the limited number of physical controls (and a lack of a line-out) mean I'd never want to use this thing myself.
