Background and key transitions
Key cut
Suppose that in step 2 of the procedure above you pressed just the KEY 1
button, and then in step 6 pressed the CUT button. This cuts key 1 in or out,
i.e. instantaneously, and amounts to a cut transition on the M/E bank.
On the other hand, using the KEY ON button in the key control section, you
can cut the key in (or out) independently of the transition on the M/E bank.
For details of key cut operations with the KEY ON buttons, see page 4-34.
Key mix
Using the KEY MIX button in the key control section, you can fade a key in
or out independently of the transition on the M/E bank.
For details of the operation of the KEY MIX buttons, see page 4-35.
Checking the status of keys and their priority
The ON and OVER indicators above the KEY 1 and KEY 2 buttons in the
transition control section provide additional status information for the two
keys. The following table shows the significance of the various button and
indicator states. (The key whose priority is indicated as "over" is the key
which appears when the two keys overlap.)
