Operations; Identity; Inversion - Orthogonal Devices ER-102 User Manual

Operations

Whenever you apply a transform, all of the operations that it contains are applied
sequentially in the following order to each step parameter:
1. Add RANDOM(Rd)
2. Multiply by G
3. Add JITTER(Jt)
4. Add A
5. Quantize to Qt
The result is the following formula:
P = QUANTIZE(G*(P + RANDOM(Rd)) + JITTER(Jt) + A,Qt)
after before
where,
P
: The new value of the step parameter
after
P
: The old value of the step paramter
before
QUANTIZE(x,y): Round x to the nearest multiple of y
RANDOM(x): Random integer between 0 and x (uniform distribution)
JITTER(x): Random integer between -x and x (uniform distribution)
If for a particular step and parameter, the transform results in a P
the valid range of the step parameter then the transform will have no effect on that
parameter. For example, trying to subtracting 50 from CV-A = 12 will have no effect.
TIP: In the case of non-destructive transforms, the Jitter and Random operations are
re-evaluated every time a target step is played.

Identity

A transform with all default values for each of its operations has no effect and is
called the identity transform. You can quickly reset any transform back to its identity
by pressing the DELETE button while in the TRANSFORM EDIT screen.

Inversion

You can invert a transform that you are editing by pressing the INVERT button. Also,
you can apply the inverted version of a transform by holding the INVERT button
while pressing and releasing the MATH button. Transform inversion only applies to
the Add (A) and Multiply (G) operators.
