^this. It's the reason I'm starting to lean away from mobile gigs and my current club gigs, Just not the same as mixing what you love to hear - electro, dubstep, dnb in my case
drumstep is 170-180 bpm version of dubstep - a fusion of DnB & dubstep. your talking about moombahton / moombahcore, which is 110 bpm electro style stuff
o woops, i need to lrn2read! um yes it is only mapping it as a midi controller thats really the only way youll be able to get it to show up in traktor recordings. drivers are actually here for the kaossilator - http://www.korg.com/kaossilatorpro
to be able to record it with an s4 you'll need to hook it up in midi mode. I have never done this, but i found these links when i was helping cupe with it: See if that helps
