I just attended the NAMM show at the Anaheim Convention Center. I don't have much to say about it, except to complain about the layout. They used to put all the DJ gear in one spot, near the arena. Now, DJ vendors are peppered all throughout the entire show. It was exhausting trying to get through the whole thing, and I still feel like I missed some vendors.
There wasn't much there to excite the Mobile DJ industry. Serato was demonstrating a program that lets you use 4 turntables at once. Hurray for all you 4 handed DJs out there! Another company was trying to sell a 10' cable for over $100 that could be adapted to various applications. You could use it for a guitar, or snap on some new ends and use it for a microphone. Who would want such a thing? It seems like a solution without a problem to me.
