Press some buttons on your Launch Control, and look to see what channel it is transmitting on. To do this, launch Mixxx in MIDI debug mode from command line: mixxx -mididebug
Note: in order to get the LED functionality working, you might need to set your template number in the JS file. You’ll have to set up LEDs for this part yourself though. This mapping currently only uses the User template, so there’s a whole second layer that can be set up with the MIDI learning wizard however you want.
Left Arrow/Right Arrow: Shifts the shown grid left or right by one scene. On the Launchpad Pro, hold the Shift button while using the Up Arrow/Down Arrow buttons to shift the grid up or down by groups of eight. The Launch Control has 2 templates (User and Factory) that are available from buttons on the unit. Navigation arrows: Up Arrow/Down Arrow buttons: Shifts the shown grid up or down by one track. The default is low brightness, amber LEDs. There is a “user settings” section near the beginning of the JS file that allows you to set global brightness and your choice of LED color for pads 1-8 (amber, red, green). The lower two arrow keys send audio from each deck to the corresponding effects (deck 1 goes to FX1 and FX3, deck 2 goes to FX2 and FX4).The top two arrow keys control headphone send to effects (deck 1, deck 2).Super knob: leftmost knob for pad 1 and pad 5 have special powers - they are super knobs, so they control all the meta knobs for that deck.You can change which parameter using the MIDI learning wizard within Mixxx. Leftmost knob controls the meta knob for that effect, rightmost knob controls one effect parameter.The LED in each pad shows if the corresponding audio effect is on or off.Pads 1-4 turn on/off effects 1-4 on Deck 1, and similarly with pads 5-8 for Deck 2.The following description assumes you have your controller laid out in the same way. Physical set up: I have my controller turned 90 degrees to the right, so pad 1 is furthest away from me, and pad 8 is closest. Copy both files into your Mixxx controllers directory - see here for folder location: /wiki/doku.php/con … _locations
