// DJ Tech Tools MIDI Fighter
// By RJ Ryan (rryan@mit.edu)
// For Mixxx 1.8.0+
// These scripts are the basics of mapping buttons on the MIDI Fighter to do
// things in Mixxx. Since everyone will have their own preference for what each
// button should do, the basic mappings do nothing more than assign player 1's
// hotcues 1-8 on the top two rows and player 2's hotcues 1-8 on the bottom two
// rows.
// If no mapping is given for a button then the function
// MIDIFighter.buttonX_down will be called when the button is pressed, and
// MIDIFighter.buttonX_up will be called when the button is depressed. This
// makes it easy to extend this script with custom functionality.
// The MIDI Fighter is laid out like this (in terms of the button numbers
// referenced below:
//
// || <-- usb wire
// ================
// | 1 2 3 4 |
// | 5 6 7 8 |
// | 9 10 11 12 |
// | 13 14 15 16 |
// | MIDI FIGHTER |
// ================
// A big thanks go to Ean Golden of DJ Tech Tools for sending me a MIDI
// Fighter. Mixxx would not have a mapping for the MIDI Fighter if it weren't
// for his generosity.
