Pressing a pad that corresponds to the current (i.e. last transmitted) value of a fader will cause
that same value to be sent again, and any currently-in-progress transition will be aborted.
The message to select Faders layout has to set them to colour 0 (off) to maintain compatibility
with Ableton Live. (Colours can subsequently be set with a Fader Setup sysex message.)
When a layout change request is received while a fader is still moving, the Launchpad stops the
fader movement and selects the new layout.!
In the case of the round buttons, the Fader layout is like the Note layout, sending MIDI CC
messages. The round buttons also self-illuminate when pressed, unless disabled in the set-up
page.
! Virtual Pan Controls
A virtual pan control is similar to the virtual fader control. A pan lights both the fourth and fifth
pads (counting from the bottom) i.e. the two middle pads when a value of 63 or 64 is received.
Their operation will be similar to that of the faders, however pads will light outwards from the
centre, e.g. if the value is 0, then the bottom four pads will be lit. If the value is 127 then the top
four pads will be lit. If the pan control is in the centred position then both middle pads will be lit.
(See figures 10 and 11.)
