ERASE
Automix ERASE cleans out Automix events between the IN and OUT points. This can
be useful when you’ve recorded parameter value changes you decide you don’t want,
preferring to let an earlier parameter value remain in place until the OUT point.
COMP/EXP.
The Automix COMP/EXP. (“COMPRESS/EXPAND) edit operations allow you to lower
or raise parameter values in the selected region. COMP/EXP. actually contains three
separate operations:
•
Compression and Expansion
—change parameter values according to their distance
from a specified threshold value (“T” stands for “Threshold” in the illustrations
below). Use compression to make value changes in the selected Automix data
region less extreme while retaining their basic character. Expansion makes the
difference between your highest and lowest values more extreme.
•
Shift
—subtracts or adds a single specified amount to all parameter values in the
selected region. You’d use Shift to simply raise or lower the selected values by the
same amount.
Parameter Value Percentages
The COMP/EXP. edit operations identify a parameter’s values based on where they sit
within the entire 100% range of the parameter’s possible values. This allows you to
identify the desired threshold value for compression/expansion, and helps you know
how much shift to apply to an Automix region’s parameter values, regardless of the
kind of automated parameter you’re working with.
Compression and Expansion
Compression and expansion decrease or increase, respectively, the distance between
the region’s parameter values and a threshold parameter value. You can select as your
threshold any of the parameter’s possible values, from 0 for its lowest value, to 50 for its
middle value, to 100 for its maximum value. Set Expand to the amount by which you
