Key Modifier Mode Definition
Key modifier mode is defined by one of the following conditions:
Note A key does not have to be visible on the Program or the Preset bus in order
to be in Key Modifier Mode.
■ Exactly one key is selected and/or active (low or high tally), or
■ Any Key Select button is selected and held down (its tally will not
change).
While the Key Select button is held, key modifier buttons may be pressed
or any key modifier potentiometer can be adjusted. If such changes are
made to the key, releasing the
Key Select button will not change its orig-
inal tally. However, if no changes are made to the key, releasing the Key
Select button will cause its tally to toggle.
Only one key can be modified at a time, and only if in modifier mode. If
multiple
Key Select buttons are held simultaneously, the left-most one is con-
sidered to be selected.
If no key is in modify mode, key modifier buttons tally off. If a key is in
modifier mode, key modifier buttons tally off/low as per the state of the
key.
Matte Button
Pressing this button ( Figure 2-11 on page 2-24 ) fills the selected keyer in
modifier mode with an internally-generated matte signal (matte fill). The
Brightness , Saturation , and Hue knobs can be used to control the matte gener-
ator parameters (while holding down the Mode/Function button) as desired
or a default matte can be set or recalled as explained below.
When selected, the Matte button will tally low if it was off, or stay low tally
if it was already selected. If an adjustment was made, the Matte button will
always remain selected (low tally) when the button is released. It may be
held down during these adjustments.
If no adjustments are made, the Matte button toggles between off and low
(selected) on button release.
Set and Recall Matte Default
To set a matte fill default the keyer must be in modify mode, viewable on
the Preview Monitor, and not on-air. Perform the following steps:
Note This is the only default value (refer to Table 2-5 on page 2-32 ) that is set at
the MMCP rather than from the Configuration Manager on the PC.
1. Press the Matte button to enable matte mode on the selected keyer.
