Serial Preset Buttons
The Serial Preset buttons are more flexible. There are four banks,
each bank containing five F-Keys and five transport buttons.
There are four Gang buttons above each bank. These buttons let
you direct the bank’s output to one or more serial ports.
While more than one of the five F-Keys can be active at once, the
transport buttons act like “radio” buttons. That is, only one can be
active at once. Sorry, you can’t Record in Rewind. It’s a feature.
If that’s actually a problem, let us know.
