Howdy John,

The short answer is "no"

The explanatory answer is as follows.

Composer holds a lot of information about the score, not just the "notes" notation (as you know). Things can get complicated quite quickly as to whether the user wants to move just notes, or MIDI controller (cc) events (eg. volume changes, Pan, etc.) or both. Therefore, there are different ways of doing the different manipulations.

If you select a group of notes and shift them, the notes do indeed move, and their associated note velocities. But the volume graph, pan graph, or any other controller data do not get shifted - they remain associated with their particular measure/tick location in the score.

If you want to copy over an entire bit of your work - all the notes, velocities, volume graph, pan graph, etc. - then you need to

(1) Make sure you're in the Notes tab (ie, the Graph is OFF, even just "Show Graph") and select the Region
(2) copy it (Ctrl + C)
(3) select the region where you want to put all that information
(4) Paste it (Ctrl + V is convenient).

If you select a bunch of notes, or a region and just hit "Delete", only the notes get deleted - the MIDI controller data (eg. volume, pan, etc.) remains. To remove all the data - notes, cc events, etc. - you'll need to
(1) Select the region
(2) Edit -> Clear (or use Ctrl + D) to totally clean out everything.

I hope the above helps make the differences in operations a little clearer.

ttfn,
Sherry
