In Karakan you can also put a lyric on a place where there is no melody note, a MIDI time code can be used. A MIDI time code has the following form:

$measure:beat:tick$
$5:3:0$lyric

If something like this was integrated into in BB/RB it would make thing a lot easier.

Here's the help file Karakan.chm
