The dark horizontal line on the icon surface shows the volume, and the diamond shows the pan. This
means you can see at a glance the level and panning of a given track. Even more handily, the pan and
level settings can be adjusted directly from the surface of the lter icon. To change the pan, for exam-
ple, just click on the diamond and move it left and right. Figure 3.4.8 shows the volume/pan lter when
the mouse is moved over the lter surface.
Notice how the surface changes colour and the mouse-pointer becomes an up / down arrow in the
rst image. This shows that the volume/pan lter is in level editing mode. Click and drag the mouse ver-
tically to adjust the volume.
In the second image, the dark horizontal level bar is highlighted when the mouse is positioned over it.
In addition, the mouse-pointer has become a left / right arrow. This shows that the volume/pan lter is in
pan editing mode. Click and drag the mouse horizontally to adjust the pan position.
When multiple volume/pan lters are selected, changing the volume or pan on one, will affect all
other selected volume/pan lters. In particular, the effect will be proportional across all selected volume/
pan lters. If you halve the level of one of the selected lters, the volume levels on the others will also
be halved. This can be very handy if you want reduce or increase the level of a number of tracks while
keeping their levels relative to each other constant.
Tip:
Holding down a modier key, such as CTRL whilst the mouse is positioned over a volume/pan
lter switches the mouse-pointer to a four-way arrow. In this state, you can edit the pan and volume si-
multaneously.
The properties available to the volume/pan lter are described below:
Volume: Use this eld to view or edit the current volume fader level.
Pan: Use this eld to view or edit the current pan position.
Apply to midi velocities: When this option is enabled, the volume control can be used to scale MIDI ve-
locities.
Reset volume to 0dB: Use this button to quickly reset the volume to the default level.
Centre panning: Use this button to quickly reset the pan control to centred.
Mute: This button temporarily sets the volume to “–inf.” Clicking this button again restores the volume
to its previous level. This option is complementary to the main mute/solo controls in the lter section, as
it is possible to automate this control if desired, whereas the main mute/solo controls cannot be auto-
mated.
Enabled: Use this option to toggle whether this lter is active. Disabling a lter stops it from processing
the incoming signal. In addition, disabled lters typically do not use CPU resources. This option is use-
ful for making A/B comparisons. Keyboard shortcut: F.
Delete lter: Click this to remove the lter from the track.
Keyboard shortcut: DELETE or BACKSPACE.
Tip: you can place as many volume/pan lters on a track as you need. This can be useful for
reducing levels fed into lters (some VST plugins can distort easily). You may also nd it helpful if im-
plementing level fades; the rst volume/pan lter can be automated to sweep between –inf and 0 dB to
create the fade, and use the second will act as a standard track level.
