Changing Novation Launchkey mode

[AndyTuke]

I'm working through Moss's Youtube videos to get started on scripting for BW. I have a Novation Laucnkey 25 I am teaching myself with. Javascript so far.

I am struggling to get my LK25 to change modes from the script. According to the Novation programmers guide this should be achieved via

Pad modes
Pad mode changes are reported or can be changed by the following MIDI event:
Channel 16 (MIDI status: BFh, 191), Control Change 03h (3)
The Pad modes are mapped to the following values:
00h (0): Custom Mode 0
01h (1): Drum layout
02h (2): Session layout
03h (3): Scale Chords
04h (4): User Chords
05h (5): Custom Mode 0
06h (6): Custom Mode 1
07h (7): Custom Mode 2
08h (8): Custom Mode 3
09h (9): Device Select

So in my Init function I have added the line

Code: Select all

   MidiOutPort       = host.getMidiOutPort(0);

   // Set LK25 mode
   MidiOutPort.sendMidi (191,3,2);

ie Channel 16, Control CC3, value 2 for Session


But nothing happens. I'm missing something here but cant see what it is
