The [FLW] key activates the FOLLOW SOLO function for the
encoder row. This means that pressing an Output Solo/
sel will automatically assign the soloed Output to the row,
overriding the default or the [USER] selection. Note that
this FLW button cancels the FLW mode for input faders,
and vice-versa.
The {PAN} mode touch button only has an effect on Aux
busses which have been configured as stereo pairs. If
such a pair is assigned to the VST encoder row, and if
the {PAN} key is active, the encoders will control the pan
between the pair rather than the contribution level.
The {GLOBAL PRE/POST} touch button isn't used for any
encoder functions, but for the sake of completeness its
function is described here. The [PRE/POST] key allows the
user to configure Aux sends from channels, when they are
assigned to the VST encoder row, as pre or post-fader.
