Key Mix Rates
The mix rates used by the KEY 1 MIX and KEY 2 MIX buttons on the
M/E Keyer panels are independently programmable, as detailed
under the E-MEM panel TRAN RATE button description. After the
M/E keyer mix rate has been programmed for each button, the
rate is shown in the Transition panel readout only while the mix is
in progress or while the SHOW KEY button on the Keyer or DSK
panel is being pressed.
The mix rates used by the DSK 1 MIX and DSK 2 MIX buttons at the
right edge of the PGM-PST/DSK Transition panel are similarly
independently programmable, but those rates may also be used as
auto transition rates by the
DSK 1 and DSK 2 buttons on the PGM-
PST/DSK Transition panel.
DSK Key Transition Rates
When an auto transition is done on the PGM-PST/DSK Transition
panel, all transitions (BKGD, DSK 1, and/or DSK 2) take place at
the same rate. What that rate is depends on what transitions are
enabled at the time, with the programmed rate for the left-most
enabled button taking precedence.
In other words, if a BKGD transition is enabled (BKGD button lit),
the auto transition rate will be the rate displayed in the readout on
the Transition panel. However, if BKGD is not enabled, the auto
transition rate will be the programmed rate for the leftmost DSK
button—DSK 1 if it is enabled, or DSK 2 if that is the only enabled
transition.
