Thanks for the comments, but my goals here are entirely audio-visual as relates to the guitar and/or piano voicing "just played" in the middle of whatever song is current.

In case my words are compromising my meaning more than describing it, here is a picture (Big Piano, in this case) of what I would like to see when I stop the playback.

The point is simply that the chord display remains, rather than disappears, when playback is stopped.
