310 Chapter 6 Logic’s Mixing Facilities
Track Selection when Playing or Recording
You can prevent the track selection from changing when making an adjustment to a
channel, while Logic is in recording or playback mode. There’s an independent
parameter for each situation; Options > Change Track in Record Mode and Options >
Change Track in Play Mode.
MIDI Channel Strips
Operation
This section deals with the MIDI channel strips of the Track Mixer, as well as those of
the GM Mixer (see “GM Mixer Object” on page 221).
The MIDI channel strips work as a remote control for the mixing parameters of your
sound modules and synthesizers (volume and pan, for example). This is the nature of a
sequencer. The controls send MIDI Control Change Messages. They do not control any
audio signal flow within Logic. Switch on all options in the View menu of the Track
Mixer, so you can see all of the parameters described below.
Saving the Mixer Settings
The Mixer settings directly affect the Object Parameter box at the bottom left of the
Arrange window. The current settings are saved with the song. If the memory of your
sound module is not maintained by battery every time you switch it off, it will forget
any settings made in Logic. To restore these settings after reloading the song, select
Options > Send to MIDI > Used Instruments MIDI Settings from the main menu.
Extended GM, GS, and XG Functions
In addition to the GM Standard, there are extended standards created by Roland (GS)
and Yamaha (XG).
GS and XG mode allow you to select different effect programs, and to control
the level of the reverb and chorus effects.
1 Click-hold the GM field on the right side of the Mixer window. A pull-down menu
appears.
2 Select the extended standard (GS or XG). Depending on your selection, the controllers
for the extended effects will appear.
3 Select the desired reverb or chorus effect from the pull-down menu.
4 Program the desired reverb or delay time (Time parameter), by using the mouse as a
slider.
Reset Button
The Reset button transmits a GS On or XG On command, and resets all controllers to
neutral positions. This allows you to reset all connected sound modules to their
standard settings, and begin a mix from scratch. The Reset button is only available in
the Environment GM Mixer.
