Macros

ME 1 to ME 2 and then copy ME 1 to ME 3 with a macro, include a short
delay after the ME 1 to ME 2 copy.

Macros and E-MEMs

Macros and E-MEMs can interact in two fundamentally different ways. A
Macro can be created that recalls one or more E-MEMs, or an E-MEM can
be programmed to execute one or more Macros. With care, operating both
control mechanisms together can be extremely powerful. However,
improper use can create infinite loops or other undesirable behavior. It is
especially important that your Karrera system be loaded with the correct
E-MEMs and Macros and is operating in the correct mode, or unpredictable
system behavior will result from the mismatched E-MEMs and macros.

E-MEM Recalls in a Macro

The state of the

Effects Dis

and

SEQ

buttons are sent as part of each E-MEM

recall command. When recording E-MEM recalls to a Macro, make sure
these states are correct when you build the Macro. For example, if you want
the E-MEM effect to automatically run as a Sequence, make sure that button
is on when the E-MEM recall is recorded into the Macro.

Certain E-MEM commands that directly affect the work buffer require
special field-rate processing. This ensures all necessary processing occurs
once per field and is in sync with all the other changes occurring in that
same field. Delays are needed for multiple time cursor changes (

more of these commands adjacent to each other in a macro, a delay of at
least one frame between them is required for consistent system behavior.
