I haven’t made any progress since yesterday’s report, but I did finally track down our camera. This video shows what I was talking about yesterday: the MIDI Note OFF events are now visible.

Video #6: Note OFF events visualized (Quicktime streaming)

The game isn’t making any sound in this video, because I’m not playing along on the MIDI keyboard. It’s easier to see the note releases when I’m not playing along and adding all the green and red colors. The piece is the same one I’ve been using for the last few demos: Chopin Waltz in E-flat, Opus 18.

The molasses effect of lingering notes is gone, so that’s good. But the note releases are accented too much, in that the suddenness of the notes’ disappearance tends to be the most visually striking movement that’s going on. It’s also dependent on the interpretation of the person who rendered the performance in the MIDI file. My theory is that if performance-dependent note releases are ignored and instead the actual note value is reflected (regardless of whether the note should be played staccato), then the accented note releases will actually help rather than hinder the feeling of the beat, since they’ll most often coincide with the attack of the next note. I’m looking forward to testing my theory out (and then moving on past this academic theorizing).
