MMC Record Buttons
The MMC record buttons object allows you to control the record enable status of
external MMC-compatible recording devices (see “
MIDI Machine Control ” on page 844).
To create an MMC record buttons object:
m Choose New > MMC Record buttons.
Resizing the object allows you to determine the layout and number of track record
buttons.
Enable the Extra checkbox in the Parameter box to display the “V TC A1 A2” extra tracks:
 V for Video
 TC for Time code
 A1 for Aux Track 1 (or A)
 A2 for Aux Track 2 (or B)
Keyboard
You can use a keyboard object to create notes with the mouse. A keyboard object also
displays all notes passing through it. In this sense, you can think of it as a real time,
MIDI note-on monitor. Although you can record the output of the keyboard in
Logic Pro, its main purpose is for testing and monitoring in the Environment.
To create a keyboard object:
m Choose New > Keyboard (or use the New Keyboard key command).
Apart from the Icon parameter, you can also set the following in the Object Parameter
box:
 MIDI channel
 Velocity: Determines a fixed velocity value for all notes.
 Lowest: Defines the octave of the lowest note on the keyboard object. You can resize
the keyboard to control its range above the lowest note.
