There are a couple problems:
One: the sound is queued, but the menu highlight occurs immediately. I'd hoped that sound triggers on beats and half-beats would be fast enough for it to mesh with menu traversal, but it just doesn't work out that way. I'm going to need to delay menu response to sync it to the beat as well. I wasn't counting on having to sync the menu. I think the best way to approach this is to expand the timer class to emit a beat signal, and have both the menu and audio systems (and possibly others) trigger their queued actions on that signal.
Two: Pressing the up or down arrow, or Enter to select a menu option, right on the beat (or as close to it as I can humanly get) should trigger the sound immediately. Instead, it seems to be just missing the beat, and waiting until the next beat trigger to play. I'm not sure how to solve this. I'm thinking of testing to see if I'm within the first XXX milliseconds (I'm thinking maybe fifty or so) after the beat, and playing the sound with an offset of however much time has elapsed since the last beat. This will require finesse if it works at all. Too small a window will be ineffective, and too large a window will cut off too much of the sound to sound good. I guess the only way to see if there's a window length that won't cause either issue is to implement it and try it out.
So that's what I've been working on today.
Oh, yeah. My eye surgery went well. As I expected, the anticipation was far worse than the event, but that didn't make it any easier. Now that I've been through it once, I won't mind much if/when I need to do it again; knowledge dissipates fear. Honestly, dealing with the bandage for a day was the worst part. There is no longer any blood in my eye obstructing my vision. It's hazy (think looking through a petroleum-jelly--smeared lens), but that's typical after eye surgery, and my vision is improving daily. It should be back to where it was before the hemorrhage in a couple weeks.
