Instrument switching works again. It used to rely on Force Touch, which Apple removed from the Apple Watch, so on newer watches there was no way to reach piano, clarinet, and tone. Now you press and hold any note to pick one. The octave stays where you put it. Swiping up or down used to move only the note that was sounding; every note after it snapped back to the middle. Now it sticks until you change it, and it is remembered the next time you open the app. You can also swipe with nothing playing. You can see which octave you are in. The keypad shades toward the left in the low octave and toward the right in the high one, and stays flat in the middle. No more click when you jump between notes quickly. Notes now fade in and out over a few milliseconds instead of being cut off. The note you are playing stays lit while you change octaves. The watch face complication shows up properly. It used to appear as an empty dot on most faces; it now works on all of them, including the modern Infograph faces. Rebuilt for the latest watchOS.
