Delson uses Native Instruments Maschine Mikro MIDI controller to play organ samples. Phoenis uses M-Audio Trigger Finger MIDI controller to trigger drum samples, maybe one of Joe's array that he used while M2M era.
I think these remixes are totally needless and unlistenable. The instrumentals and vocals not matching. Like in brostep remixes. Instead making these crapmixes, they should do a real remix album like they did with Reanimation.
Joe uses a Pioneer RMX-1000 remix station.
You can see on this picture:
..and you can also see on this picture, he uses Serato with timecoded vinyls. (I think since 2007)
