Clear/reset patch or rename
You can reset (1:1) or clear the dimmer patch, the moving device patch, or the renaming
system for any channel range from # to #. If you check "Apply To All" you don't need to
specify a range. Unpatch All clears channel, device and name patch.
These are the options in the Clear wizard tab
See Renaming Channels
NOTE
Checking Apply To All clears everything up to the total system limits
regardless of any prior downgrade of channels/outputs.
