Lighting LEDs Using SysEx Messages
$
It is possible to control Launchpad Pro’s LEDs using SysEx messages. This allows a number of LEDs
to be updated quickly in a single message. In this SysEx message, the index of the LED is taken to
be the same as Programmer layout, regardless of the currently selected layout. This is also
applicable to the round buttons, with the LED index using the same value defined in the
Programmer layout. Please refer to figures 14 and 15.
Note that the SysEx LED message will override the colour of the specific pad LED, regardless of
the previous colour (including the special round cursor buttons.) However, if those buttons are
subsequently pressed and released, the LEDs will return to the official colour of that button. (i.e.
The SysEx message LED colour will be overridden by the default colour for that specific button on
that layout.)

<LED> <Colour> pairs may be repeated up to 97 times in the message.

! Light a column of LEDs using SysEx
$
Columns are numbered left to right, 0 – 9, with 0 and 9 referring to the round buttons. The
sequence of LED colours starts at the lowest LED, with the next colour referring to the next
higher LED in the same column. However, the LEDs that are missing from the corners (in the
columns of round buttons) still occupy a position in the message. They just cannot be seen. Also,
the side LED cannot be updated by this message.

The <Colour> parameter may be repeated within the message up to 10 times.
! Light a row of LEDs using SysEx
$
Rows are numbered bottom to top, 0 - 9, with 0 and 9 referring to the round buttons. The
sequence of LED colours starts at the most left LED, with the next colour referring to the next LED
to the right in the same row. However, the LEDs that are missing from the corners (in the rows of
round buttons) still occupy a position in the message. They just cannot be seen. Also, the side
LED cannot be updated by this message.
