Scratch Live v2.5 is now out. Updates included support for the new Serato Remote iPad app (see my other thread), CDJ-2000 Nexus HID integration, and MIDI output lighting. And of course bug fixes.
Yeah Serato has bugs but not like Traktor. Also Serato focuses more on bug fixes than gimmicks. With that said I still prefer to use Traktor because the ability to do more is present. However Traktor is such a pain in the ass to use in clubs and studios. So I use Serato.
