Hey again Bennett,
ISO Buttons isolate the channel from the automation, you can 'zoom' in to single functions on the channel by holding the ISO button and then zooming in on the functions you want included / excluded by touching on the vistonics (i.e. 1 send / all the sends, Labels / no labels, Patch / no Patch, Gain / no gain....you get the idea.
On top of this, ISO buttons can be used in conjunction with the 'scope' function of the automation (for scene by scene iso's or pasting of parameters (EG....vocal gain change etc)...Another handy button is the 'Load show with ISO' button (allows a new show file to be imported while leaving anything ISO'd from the previous show file behind (Matrix outs, output EQ, MC mic, CD player etc...
There is an addendum to the manual which relates to all of the extra function that has been added since the original manual was written (there used to be a manual kicking round somewhere that had all the complete function set included) this includes functions still not available (touch eq and dynamics at the same time and get EQ & Dynamics on the vistonics encoders at the same time....custom layers etc...)
Your software version should be 3.0.1.112 (this is the latest and includes all functions available at this time)
This version includes a 'Flat all' button in the EQ screen (push to zero....)
Still puzzled about the stage rack noise thing though....the stage rack fans do have an auto speed control curcuit....maybe something funny going on with that perhaps?
Oh yeah....another little thing that annoys me is the insert switches on the master Left / Right are still not linkable...(although everything else is).....I can't wait for that so that I can finally put a stereo pan / phaser combo ober the left / right and realize my all time dream of recreating a poor facsimile of the end of Led Zepplin's When the Levi Breaks...lol
