Reply to My custom Akai MPD32 traktor pro mapping

I wanted to have a mapping for controlling four decks, that would allow full fx control, and complete cue point access without using several pages.

So here it is (sorry for low image quality, was taken with my mobile phone).

8 pad for each deck couple (A/C, B/D) with switches to select A/C or B/D (swith 4 and 5), as well as 4 knobs.

I have four pads for play / pause, cue, loop (4 bars, with auto phase sync), and sync (set as slave + phase sync). 4 pads will be used to access cue points 1-4.

The four knobs acts as following:

• Filter on + value
• Key on + value
• beat jump (one beat) left or right
• loop size increase / decrease (with phase sync on increase)

Sync pad also acts as a shift pad: when pressed, cue 1-4 become cue 5-8. Play pad would become filter off and reset, cue pad becomes key off and reset. When the sync pad is pressed, the beat jump knob jumps 16 beats instead of one.

When the loop pad is pressed, the beatjump knob acts as a loop move knob (one beat).

Fx section is rather complete: I use fx in advanced mode only (since I have a DJM800, I do not need multiple fx slots, fx layering is done through using fx/color fx sections of mixer). 4 faders control dry/wet and three params of the effect. I also have two switches that are assigned to the two fx buttons.

Fx configuration is done pressing switch 1 and 8, respectively. I can engage fx on deck 1-4, select fx using pads.

Took me a lot of time to build this mapping, particularly because of the knobs behavior of the MPD32: the only endless behavior is implemented using nrpn, which of course, Traktor does not understand.

I first tried to use MidiPipe and Bomes Midi translator, but no luck, I did not have the behavior I wanted. So I made my own little Java program that translates NRPN either to 1-127 rotary encoders, or two note ons (one for each direction) wth adjustable sensitivity (because control would be way to sensitive otherwise).

I also have to say that Traktor midi configuration truly sucks, they should have allowed bulk duplicate/modify of a set of mappings.
