I use VDJ Pro ver. 7, just recently purchased it in the last month, for a while i was using PCDJ Red Mobile before I had a controller, for about 2 years, last year on a whim I bought a used Numark Stealth controller just to get my feet wet. It came with traktor le, I didn have external sound card, so I struggled some with that, played around with mixmeister fusion, I like that for studio type stuff, I like the feel (so to speak) of VDJ, already looking to upgrade controller, but I’m opting for becoming proficient with what I have,
