A/B Switching
GCX loops can be used for A/B switching. The following are two examples.
Example 1. Selecting between two preamps:
When the loop is OFF, Preamp-1 feeds the audio out. When the loop is ON,
Preamp-2 is selected.
Example 2. Selecting between two amps:
When the loop is OFF, Amp-1 plays. When the loop is ON, Amp-2 plays.
Muting Sends
Loops can be used to mute the input to effects.
When the loop is ON, "Audio In" feeds the input of "FX". When the loop is
off, the input to "FX" is muted.
