© Focusrite Audio Engineering LTD 22Pulsing!Launchpad Pro supports pulsing between two colours in Programmer layout and Ableton Livemode, but implemented quite differently. In Ableton Live mode, pulsing is started by sending theLED a Note On message (or CC message for the round buttons) on channel 3 and can be stoppedby sending a message to the LED on channel 1.Programmer mode does not reserve the MIDI channels for pulsing, instead it uses a SysExmessage to implement pulsing.For pulsing, the colour of the LED rhythmically increases and decreases in brightness, shown infigure 17. !!!!!!!!!!!!!!! Pulse LED using SysEx$The LED will pulse between the chosen colour and its current colour. The side LED can also beupdated by this message. It has an LED index of 99 (63h).Host >> Launchpad Pro: F0h 00h 20h 29h 02h 10h 28h F7h(240, 0,32,41,2,16,40,, , 247)The parameter pair may be repeated in the message up to 97 times.To stop pulsing just send a standard Note On message or SysEx message to the same pad and itwill be cancelled.!RGB Mode$The brightness of the individual red, green and blue elements of the LED can be controlled tocreate any colour. Each element has a brightness value from 00h – 3Fh (0 – 63), where 0 is off and3Fh is full brightness.!! Light LED using SysEx (RGB mode)$The side LED can also be updated by this message. It has an LED index of 99 (63h).Host >> Launchpad Pro: F0h 00h 20h 29h 02h 10h 0Bh F7h(240, 0, 32, 41, 2, 16, 11, , >, , ue>, 247)The group may be repeated in the message up to 78 times.Figure$17:$The$pulsing$waveform$
