Chapter 25 Mixing 597
 Chorus Depth (Controller Number 93): This knob controls the depth of the chorus
effect. The further right you turn the knob, the stronger the effect becomes.
 LPF Frequency (Controller Number 74): This knob controls the overtone content of the
sound. Higher values make the sound brighter.
Saving and Restoring MIDI Channel Strip Settings in the Mixer
The Mixer MIDI channel settings directly affect the Track Parameter box shown in the
Arrange window Inspector. The current settings of all channel strips are saved with the
project.
If the active settings of your sound module are not maintained when you switch it off
(some devices reset to “default” values), any Logic Express Mixer settings that affect the
unit will be lost. Thankfully, Logic Express Mixer settings are automatically restored (and
transmitted to all MIDI devices) when you reload the project.
On occasion, however, this may not happen, due to MIDI communication issues with
some devices. In this situation, you can manually resend the Logic Express MIDI
channel strip settings by choosing the Options > Send All MIDI Mixer Data command.
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.
To display the GS or XG effects:
m Enable the Add GS/XG Effects setting in the Mixer’s View menu.
The GS/XG configuration control is displayed on the right of the Mixer window,
allowing you to select different effect programs.
To configure GS or XG effects:
1 Choose the desired standard in the first menu.
Depending on your selection, the controllers for the extended effects will appear.
2 Select the desired reverb or chorus effect from the second menu.
3 Program the desired reverb or delay time (Time parameter).
