In this simple example, slider control Sl1 – represen-
ted by the vertical line – is halfway between the back-
ward limit and the midpoint of control travel (input =
-50 %). However, "Point 1" will be relocated to control
centre at a point value of +50 %, resulting in a mo-
mentary output value of -25 %.
One touch on the centre
ESC
key of the left touch
pad will terminate this trim point function.
Trim offset function
When a value field is active, i. e. in inverse video, it is
not only possible, as previously described, to jump up
or down to reference points already set with the
selection keys of the left touch pad and to make a
change with the selection keys of the right touch pad,
but also an existing curve can be vertically reposi-
tioned within a range of ±25 % through use of the
keys on the left touch pad. Starting with a point value
for "Point 1" at 0 %, the control curves in both of the
following figures have been vertically shifted within
the ±25 % range by the trim offset function:

You can also exit this function by tapping the centre
ESC
key of the left touch pad.
Trim x-axis function
This function is activated by tapping the left () or
right () selection key of the right touch pad with an
active (i. e. inverse video) value field. You can then use
the selection keys on the right touch pad to reposition
the active point horizontally or vertically as you wish.
In the figure below, "Point 1" which was just shifted to
+50 % with the trim point function, will now be shifted
to the left:

Notes:
•
If the point is repositioned horizontally
further away from the current control
position than approx. ±25 %, a "?" sign will
reappear in the line Point. This question mark
does not refer to the repositioned point, however:
1
instead, it signifies that a further point can be set
–
+
at the current control position.
•
Please note that the percentage value on the
"Output" line always relates to the current stick
position and not to the position of the point.

This "angular" curve profile created in the example
can be smoothed automatically simply by pressing a
button. Do this – from a situation as illustrated – with a
brief tap on the selection key of the left touch pad.
This will result in a switchover from "(Curve) off" to
"(Curve) on" (or vice versa):

The curves shown here are for demonstration

of real mixer curves. For real-world application
examples, see the programming examples on pages
