Description

Per http://lmms.io/forum/viewtopic.php?f=7&t=1421&p=5900#p5900

I know this is a user problem, but it would be nice for the piano roll to be usable when its first opened, like the BBEditor is by simply defaulting to the first relevant track. If not, the piano-roll button should probably be grayed out until at least one piano roll has been created.

Research direction

Start by reproducing the piano roll behavior when it is first opened from the SongEditor, and compare it with how the BBEditor selects a relevant track. Investigate the piano-roll button and the first relevant SongEditor instrument. Done means the piano roll opens on the appropriate instrument, or the button remains disabled until one exists.
