Stereo panning
The following chart demonstrates the results of
stereo panning. In general, center the knob for full
separation of the stereo signal.
☛ The Trim plug-in (see “Trim” on page 90 in
the DP Plug-in Guide)can be used to invert the
phase of an audio signal or constrain the stereo
image of a stereo track.
Volume faders
The volume faders control the output level for each
MIDI and audio track by generating MIDI and
audio volume events, which can be recorded into
the track for automation. If automation data has
been recorded, faders will animate during playback
(when the Automation play button is enabled).
☛ If the fader cap is missing, it means that the
audio track has been disabled. See “Enabled” on
page 142.
MIDI volume has a scale from 0-127; audio volume
is expressed in decibels (dB) where zero is unity
gain. Audio faders provide an additional +6 dB of
boost above zero dB. For example, if you move a
fader in the Mixing Board as high as it can go, it will
be set at 6.02 dB above unity gain. This range is
provided throughout the program, wherever audio
volume data values are displayed.
The background color of volume faders changes
depending on the solo and mute state of the track.
See “Solo / Mute buttons” on page 812 for details.
Below is a summary of mousing techniques for
changing the values of Mixing Board volume
faders:
Figure 70-28: The many ways to control a fader.
Using MIDI note velocities to control volume
MIDI notes have on-velocities that affect their
volume. The range is from zero to 127. You can edit
velocities individually in the edit windows, or you
can use the Change Velocity command in the
Region menu. Keep in mind, however, that velocity
only affects the initial volume of the note and offers
no way to change the note’s volume while it’s
playing.
Controlling pan, volume and send controls from
an external MIDI controller
To control a volume fader, pan knob, send level
knobs, send pan, or send mute buttons from an
external MIDI controller such as a mod wheel on a
keyboard, use the Attach MIDI Controller
