Here's a document of my controller mapping TWEAKS. Set up on the DENON MC7000 but will easily work well on others.

Waveform Display Zoom
Pitch Fader Lock
Loop Back Mode
FX Show GUI
Bit Crush
Echodoppler
Quick reload to previous loaded track.
Improved L.Prep Sidelist load & Delete
Improved Browser Controls

And the most wanted...
Emulated PIONEER COLOR FX assignable to the Filter Knob
Crush/DubEcho/Reverb/Jet
Can also be Noise or Riser if you'd prefer it to be selectable instead.
Even better than Pioneer, either Filter Knob can be any at the same time.

Here's the LINK all with visual LED referencing.

More ideas welcome. We can take our controllers and mixes to the next level.
