Techno - What does this mean? In pursuit of technology, trying to keep up with it, trying to stay ahead of the game.

I've been playing 3 decks ever since i got bored on two. Its not that you're standing around waiting to mix, cos if you are, maybe hard-house is you thing.
There is infinitely more scope for mixing with 3 decks. You can really push a sound with 3, and EQing really comes into its own. You're extending the limits of what you can do in a set.
It was techno which pioneered 3 deck mixing, as a way of mixing quicker and manipulating what you're playing more into what you want. No matter how hard you try on 2 decks, you simply can't create as deeper sound as with 3.
Admittedly, there are people out there who think that just cos they can fudge a few tunes together on 3 decks, that makes them great. Bollocks.
But when you see someone trying to use the third deck to actually MIX tunes not just play them, then they deserve respect for it, cos at least they're trying to push the boundaries, and do something different.
The third deck, or fourth is just a tool, like an effects unit. Not there to be relied on, but there to be used when desired.
