Region Gain and Automation
Mixbus has 2 separate types of automation: Region Gain and Automation. Region Gain envelopes are often used
for repair work, such as reducing unwanted breaths, accentuating syllables, or reducing noise. Automation is often
used for creative changes such as fading elements in and out during a song. Region Gain only adjusts the volume
(level) of the region across time. Automation can be applied to many different mixing parameters including the input
trim, fader, panning, or plug-in parameters.
Region Gain
Region Gain is a volume envelope that extends
for the length of the region. By default, the
region envelope is "unity" (i.e. no change) across
the entire region and it is hidden. To adjust
region gain with the mouse, you must use the
Gain tool. The first click on a region with the Gain tool will cause the gain
line to appear. By default , a region has 2 control points, one each at the
start and end of the region.
Mouse operations using the Gain tool inside a Region:
• Click anywhere in the region to create a new control point, and con-
nect it to the points on either side.
• Click a control point to grab it and move it.
• Click a line to move the gain points on either side of the line.
• Click in the region and drag to create a "range". Now click inside the
range and you can drag the entire range up/down.
• Cmd/Ctrl click on an existing line to add a new control point.
Operations available in the Region menu and right-click context menu
include: Show/Hide Gain Line, Enable/Disable Gain Line, and Reset Gain
Line.
Automation
Many mixer parameters may be automated: fader, mixbus sends, eqs, compressor, and even plug-in parameters.
Realtime Automation: Touch Automation
In Realtime automation the parameter is put into a "record" mode. The moves are recorded while the user moves
the knob. There is an automation button next to the fader because this is a very commonly-automated control. You
can automate nearly every mixer parameter by showing the automation track for that parameter and setting the
mode. Here is a description of the modes:
The mouse wheel has a slightly different automation mechanism. When the wheel is turned, it "touches" the param-
eter and begins recording the move. The automation continues to record until the transport stops. This is some-
times called "Latch" mode.

Section 14.0 - Mixbus Automation
Mixbus User Guide
Tip: If you want to quickly change
the gain over the entire region, then
click on the region to show the line, and
then grab the line and move it up/down.
This is an alternative to Region Level.
Tip: This is an excellent way to
tweak a syllable or reduce a section
of noise, and it is often more transparent
than deleting it entirely.
Tip: You can right-click on the
range and choose "reset gain line"
to return the gain line to unity through
the length of the range.
Manual
Automation is ignored.
Play
Whenever you locate, the parameter will jump to the value that is recorded in the automation. You can-
not change the value manually
Write
When locating, the value will stay as it is (no playback of automation). During playback (only), the cur-
rent value will be written to automation. You can move the control manually and your move will be writ-
ten to the automation.
Touch
The parameter will act like it is in Play, unless you "touch" it with the mouse. Then it will record your
moves until you release the mouse button.
