210 Controlling Playback
Changing Track Settings
(such as Bb trumpet). For more information, see the online help topic
“Music Notation for Non-concert-key Instruments.”
When you edit the Key+ parameter, pressing [ or ] changes the value by 12
instead of by 10. This makes it easy to transpose by octaves.
To Set the Key Offset for a Track
1. In the track you want to change, click on the Key+ control.
2. Enter a value (1 = a semitone), or press the + or – key to change the
key by a single semitone. Use the [ or ] key to change the key by 12
semitones (one octave).
To change the key offset for more than one track at a time, select the
tracks you want to change and choose Tracks-Property-Key+.
Adjusting the Note Velocity (Vel+)
Each MIDI note event has a velocity, which represents how fast the key
was struck when the track was recorded. On playback, the velocity offset
parameter adjusts the velocity data for all notes in the track by the
designated amount. The value can range from -127 to +127. The effect of
changing velocities depends on the synthesizer. Some synthesizers do not
respond to velocity information. For others, the effect varies depending on
the sound or patch you have chosen. Normally, higher velocities result in
louder and/or brighter-sounding notes.
This parameter does not affect the velocity that is stored for each note
event. When the clip is displayed in other views, like the Piano Roll view,
Staff view, or Event List view, you will see the original velocities as they are
stored in the file. You can edit the velocity values in those views, or use the
Process-Scale Velocity or Process-Interpolate command.
Velocity is different from volume in that it is an attribute of each event,
rather than a controller that affects an entire MIDI channel. Here’s an
example of where this distinction might be important. Suppose you have
several tracks containing different drum parts. All of these parts would
probably be assigned to MIDI channel 10 (that’s the default channel for
percussion in General MIDI). If you change the volume setting for any track
that uses channel 10, all the different drum parts—regardless of what track
they’re in—would be affected. If you change the note velocity for one drum
track, it will be the only one whose volume is affected.
To Set the Velocity Offset for a Track
• In the track you want to change, click and drag the Vel+ control to the
desired setting.
