Flashing

Launchpad MK2 supports flashing between two colours on all three layouts. The flash colour is

set by sending a note-on message (or CC for the top 8 round buttons) to the device on channel 2.

When a message is received on channel 2, Launchpad MK2 will then begin to flash between the

flash colour (B) and the current colour of the LED (A), with a 50% duty cycle (shown in figure 7).

Flashing (and pulsing) happens in time with MIDI beat clock (see ‘MIDI Clock’ below), the last

known tempo or will default to 120 bpm.

Flashing can be stopped by sending the LED a message on channel 1.

! Example: set a single pad to flash between red and off (Session layout)

The LEDs are all off. Set the bottom left LED to flash between red and off.

Host >> Launchpad MK2: Channel 2: note-on B-1/0Bh (11), velocity 05h (5)

91h 0Bh 05h (145, 11, 5)

The LED will flash between red and off. The sequence will start with red.

To stop flashing and turn the LED off:

Host >> Launchpad MK2: Channel 1: note-on B-1/0Bh (11), velocity 00h (0)

90h 0Bh 00h (144, 11, 0)

! Example: set a single pad to flash between red and green (Session layout)

The LEDs are all off. Set the bottom left LED to light green.

Host >> Launchpad MK2: Channel 1: note-on B-1/0Bh (11), velocity 15h (21)

90h 0Bh 15h (144, 11, 21)

Set the flash colour to red, start flashing.

Host >> Launchpad MK2: Channel 2: note-on B-1/0Bh (11), velocity 05h (5)

91h 0Bh 05h (145, 11, 5)

The LED will flash between red and green. The sequence will start with red.

To stop flashing and turn the LED blue:

Host >> Launchpad MK2: Channel 1: note-on B-1/0Bh (11), velocity 2Dh (45)

90h 0Bh 2Dh (144, 11, 45)
