Keys
Selecting an unmodified edge
When all four of the edge type selection buttons are off, an unmodified
("normal") edge is selected. If one of the buttons is lit, press it, turning it off.
Using the processed key function
To use the processed key function to apply special effects to the key using a
DME, press the PROC KEY button, turning it on.
For details of the processed key function, see page 4-52.

Key snapshot operations

Using the key snapshot function, you can instantly save all of the key
settings, except the key on or off state, in a special-purpose register.
Recalling a snapshot restores all the settings instantly. There are four
snapshot registers per keyer.
To save an M/E key snapshot
For example, to save the state of keyer 1, first press the KEY 1 button in the
key control section to delegate the key control section to keyer 1, then hold
down the SNAPSHOT button in the FlexiPad for the corresponding M/E
bank, and then press one of the key snapshot buttons 1 to 4 in the key control
section.
This saves a snapshot in the register corresponding to the number of the
button pressed.
Note
If the M/E key snapshot button is lit, this indicates that there is already a
snapshot saved in this particular register. If with the SNAPSHOT button
held down you press an M/E key snapshot button which is lit, this overwrites
the previous information in the register.
To save a DSK key snapshot
For example, to save the state of downstream keyer 1, hold down the
STORE/LEARN button in the numeric keypad section, and press one of the
key snapshot buttons 1 to 4 in the DSK control section.
This saves a snapshot in the register corresponding to the number of the
button pressed.
