Down here controllers are very few (in fact very rare, at least in clubs & in other public gigs) & lots of DJs are on CDJs running on either CDs or SSL. The rest are Virtual dj crackers running on keyboard and mouse(and a great deal of wave riding) who you are most likely to find in pubs and other drinking joints with no real established sound. Music revolves between local & international top 40, rhumba, reggae and local folk. I haven’t ever seen (or heard) a DJ down here using Traktor save for a buddy of mine who bought a Mixtrack Pro & got the LE version that came with it.
