Alternatively, if the [e] buttons for two different channels
are pressed at the same time, it will be possible to edit
both of those channels simultaneously.
In such a case, 16 of the [Multi function knobs] can be
used with each. Of the two channels, the one on the left
can be controlled by the left bank of 16 knobs and vice-
versa.
If you again press the [e] button for a channel being
edited, the "Mixer" will reappear. It should be noted that,
even when Channel Setting mode is active, the specific
parameters controlled by the individual [Multi function
knobs] can be changed in the SECTION CONTROL
section.
The [Touch slider bar] is a touch controller for scrolling
through the channels. When you slide your finger along
the bar, the channels scroll across corresponding to the
distance your finger travels.
