Apple Logic Pro 7 - Manual (Page 59)

Chapter 1 Using Logic 59
Should you wish to use the Space bar key command (usually Start/Stop), rather than as
the Sustain function for the Caps Lock Keyboard (when active), you can disable the
Preferences > Global > Caps Lock Keys > Space bar acts as Sustain Pedal option.
Additional Caps Lock Keyboard Info
Due to technical limitations of computer keyboards, there is a maximum number of six
notes that can be played simultaneously. There are further limitations regarding timing
precision, and when trying to play certain note clusters (which are musically unusual, at
any rate).
Please keep in mind the original intention of this facility—as a useful aid when
composing on a train or plane—not as a full-on replacement for a real MIDI keyboard.
Song Administration
All events, other objects and settings (apart from the preferences and key commands)
are components of a song. Songs are handled in the main File menu.
Projects
The illustration above shows a typical Project folder file structure in Logic’s Open
dialog.
