Currently BB can import a MIDI melody file on to the BB Melody track. This is a very useful function for loading melody notes from other programs.

In addition, the BB import dialog allows the incoming MIDI file to be offset from the beginning of the song by a number of blank bars. This is also useful, since users might want to start the melody after an 8 bar intro.

However, the use of the "# blank bars" field is confusing when the imported MIDI melody is viewed in the notation window, because of the 1-bar LeadIn measure that shows in the notation window.

1. Users don't know if they have to allow for the leadin measure by entering '1' in the #blank bars field in the import dialog.

2. It turns out that '1' is the wrong value anyway, since '2' is the actual number required for a correct import.

So a user (me) importing a MIDI file with an 8-bar intro to skip must actually enter '10' in the #blank bars field to correctly place the notes in the BB score.

Ironically, the tooltip for the import dialog #blank bars text field correctly advises that '2' should be used. (I didn't even know that tool tips were possible for static text strings).

The confusing things are:
1. A 1-bar Leadin is always visible.
2. This doesn't match the '2' that is required.
3. The '2' value is only mentioned in the tooltip.

Perhaps the '2' is a legacy number from some old code, or from a missing Leadin bar under the hood somewhere in the code.

Perhaps this information could be added to the MIDI track importing documentation one day. If it was me, I would also include a screenshot of the tooltip on the #blank bars field, to help users see that there is a tooltip to help them.
