Between Different Devices
Select the source device (Device menu). Select Edit > Copy, and change to the target
device (Device menu, again). Select Edit > Paste. The standard Copy/Paste key
commands can be used, as well.
Track Mixer
To open, select Windows > Track Mixer.
Note: If you press Option while opening a Mixer window, it will appear as a float
window.
Unlike the Audio Mixer, the Track Mixer deals with both audio and MIDI tracks. Each
channel represents an Object in the Environment: the audio channels are Audio
Objects, the MIDI channels are instruments or parts (sub-channels) of multi
instruments.
Tracks that don’t have their own mixer parameters are not visible in the Track Mixer.
These include Delay Objects (see “Delay Line Object” on page 230), Arpeggiators (see
“Arpeggiator Object” on page 228), and so on. If several tracks in the Arrange window
address the same track instrument Object, the instrument is represented by a single
channel in the Track Mixer.
Note: You can adjust the vertical and horizontal display of the Track Mixer with the
Zoom controls.
Display Modes
The Track Mixer has two display modes: Global and Track view.
In Global view, all MIDI instruments and all Audio Objects that exist in the Environment
are displayed as mixer channels.
In Track view, Logic creates a mixer based on all tracks currently assigned in the Arrange
window track list. It contains as many channels as there are tracks. The channels are laid
out in the same order as in the Arrange window. Redundant tracks are suppressed,
where multiple tracks represent the same output (Object). This could be two MIDI
instruments with the same port and channel setting, or two Audio Objects with the
same device and audio channel/track setting.
If you miss an Object you need for mixing (an Audio Output Object, for example), open
Global view and double-click on the Object in question. It will then be added to the
Arrange track list, and will appear in the Track Mixer when in Track view mode.
