Torq Conectiv from M-Audio is a complete package for the computer based DJ that includes Torq performance software and the Conectiv USB computer interface.
The software supports multiple digital audio formats, including MP3s, which negates having to cart around a heavy box of vinyl records or CDs. All the usual functions required for DJ work are supported within the software.
The Conectiv USB interface is very flexible in that it can function as use as a self-contained digital system, multi-effects processor, or as a slave from control CDs/vinyl. The inputs connect to all standard DJ mixers, turntables and CD players and even allows for mixing analog vinyl sources with digital tracks.
