I recommend that Overture's arrangements for transcribing regular notation to tablature be as follows. Note that this recommendation may differ in some respects from recommendation I have earlier made in this area.

1. A "regular" notation staff would carry a string tuning table, whose content is essentially as at present. When the user plans to have tablature notation for an instrument, he would set up the desired tuning table on its regular staff using the Tuning tab in Inspector>Track.

2. On the Tuning tab in Inspector>Track, the string pitches should be entered or shown as they actually are, not displaced in pitch when the regular staff in question is set up for "transposed" notation. This is of course the way we find various instrument tunings in textbooks, online tutorials, and the like.

3. If, on a regular staff, the user selects one or more notes and calls Notes to Transposition, then, without any question box or dialog being presented,the Tablature Settings dialog will appear. It initially would show the existing tuning table (from the mother staff); normally the user would have no need to make any change to that, since preferably the desired tuning table has already been placed on the regular staff by the user.

But the user could, if desired for some very special reason, change these settings so that this operation would use, ad hoc, a different tuning table. Making a change in the tuning table here wouild not change the tables subsequently carried by the regular or tab staves.

The user can change, for this particular operation, such properties as whether the tab notation should carry stems and flags.

The Tablature Settings dialog wouild, whether or not there was already a tab staff, of the form we have today when there is no tab staff: allowing the user to choose a different tuning table (or the beginning of one) in terms of a named "standard" one.

5. If there is not already a tab staff, it will be created and will carry the tuning table carried by the mother staff (not the one then set in the Tablature Settings dialog, if that differs). The tuning table carried by the tab staff does not have any currently-known purpose.

6. The tablature notation will be created from the selected notes on the mother track in accordance with the settings (including the string tuning) found on the Tablature Settings dialog.

7. If a change is made to the tuning table of a regular staff with which there is an associated tab staff (on Inspector>Track:Tuning), or a change is made there to the tuning table of a tab staff, the tuning table of the mated staff will be changed to match.

DISCUSSION

The basic notion here is that a tuning table is a property of a mated set of regular notation staff and tab staff.

When the user selects one or more notes and calls Notes to Tablature, there is no need to ask the users if a tab staff is wanted; of course it is wanted.

If the track in question is established via a template with a tab staff already associated, both staves should carry identical tuning tables. If the user wishes a different tuning table for this project, he can make the change on either the regular staff or the tab staff, and it will be applied to the other.

I forgot one aspect, which I will give here as item 6a:

6a. When notes on the regular staff are transcribed to tab notation, the process should start with the sounding pitch of the note on the regular staff (that is, the notated pitch as adjusted by the Playback Transposition value).

This, combined with the expression of tuning tables in terms of actual string pitches, will automatically accommodate any transposition of notation. (At present, accommodation of transposed notation for a transposing instrument - notably the guitar - is done by building a "fudge" into the tuning table for that instrument.)

Good points Doug!

But for various reasons—regarding #1 above—I think it best that a tablature staff holds its tuning property, rather than "inherit it" from the parent staff.

Here's why.
