Before starting, decide how you want to use the mute patch
system. Choose the recall operating mode with or without
auto increment. If you do not want to use the patch system
you can turn it off to prevent accidental operation. Refer also
to the section on MUTE SAFES for details on how to prevent
selected channels from being operated by the patches.

A mute patch lets you store the console mute on/off settings to be recalled with a single
key press. This is much like taking a 'snapshot' of the console settings. Mute patches
are used extensively for scene or song changes during live performance. The
advantage is quick access to complex changes, a growing requirement with the more
sophisticated sound control specified today. Patch changes can be linked to external
sequencers and effects devices via MIDI for sophisticated show control. Patches can
be archived and recalled via MIDI.
The GL4000 includes 128 mute patch memories. The patch number is simply dialled
up on the 3 segment display and its contents recalled or overwritten with the current
console settings. Recalling a patch does not overwrite any active groups. Patch
settings may be checked before recall by using the preview function. Selected channels
may be made 'safe' so that they are not affected by patch changes. If preferred, the
system may be disabled when mute patches are not needed.
