Making Notes the Same Length
If you want to make several selected notes the same length, hold down Option-Shift
(as in the Event List, when making several parameters the same value).
What Tools to Use
You can use either the mouse pointer or the pencil when altering note lengths. It’s
advisable to use the pointer, as this avoids the accidental creation of new notes,
possible with the pencil.
It can sometimes be difficult to grab the bottom right corner of very short notes. In this
situation, you should use the index finger tool, which allows you to grab notes
anywhere, in order to alter their length.
Altering Velocity
To alter the velocity value, click-hold, and vertically drag on the note with the V tool.
The help tag will indicate the velocity value of the note you have clicked on.
If the MIDI Out function is switched on, the note will be output when you alter the
velocity.
Altering the Velocity of Several Notes
All selected notes can be altered simultaneously; the differences in their respective
velocity values will be retained. If the velocity value of one of the selected notes
reaches an extreme value (0 or 127), none of the selected notes can be adjusted further.
You can override this behavior by holding Option while doing so. This allows you to
continue altering the velocity values until the selected (clicked) note reaches an
extreme value.
Hold down Option-Shift while dragging, to assign the same velocity value to all notes.
Hyper Draw in the Matrix Window
In both the Matrix and Score Editors you can use the View > Hyper Draw command to
open a Hyper Draw (see “Hyper Draw” on page 233) display. This allows quick and easy
editing of controller data while viewing note data.
Once you have opened the Hyper Draw display, you can select the type of event you
want to view by using the arrow menu to the left.
You can adjust the size of the Hyper Draw display by grabbing, and vertically moving
the dividing line that separates it from the main Matrix editing window.
