keyboard.

The playhead can be directly grabbed and moved with the mouse (see scrubbing).

post fader Sends in analog mixers are positioned either before (pre) or after (post) the
fader. Post fader means positioned after the volume fader in the signal flow, with the
level of a signal going to the send changing along with the fader movements.
pre fader Sends in analog mixers are positioned either before (pre) or after (post) the
fader. Pre fader means positioned before the volume fader in the signal flow, so the
level of a signal routed pre-fader to a send remains constant, regardless of any fader
movements.

menu. All Logic Express preferences can be set in this window.
preset Set of plug-in parameter values that can be loaded, saved, copied, or pasted via
the Settings menu in the plug-in window header. See setting and Settings menu.
