I use this to mainly have quick fun by myself or with my friends, without the inconvenience of carrying or wiring mixers, turntables and etc. For this task or for learning basics of DJ-ing this is a very good controller. It is really well built and feels sturdy. All the buttons and knobs feel really good and clicky. I only don't like the hotques/sample buttons at the bottom, but lets say that they are OK. Few other things that I find annoying:
- Most of the people have said this already, but yeah - why removing the effects knobs, when the MK2 already has it. It can get quite boring using only the mixer FX ( you can use only 1 for each channel). You could use custom mappings for free, which are not ideal or invest in a Kontrol X1 (which is not so cheap) to manage this. Also there is not an IN/OUT buttons for the loops, but you could do a mapping in Traktor for this pretty easily.
- The pitch slider is small and beatmatching could be quite hard. Set this in your software to +/- 8% and it will be better.
- The sound coming from this is somewhat on the quieter side. Both from master and monitor
- Very limited I/O. Only 1/8" jack for the headphones, instead of the bigger more professional 1/4". Also on the back there are only unbalanced outputs (RCA) and AUX, no XLR. I recommend using XLR to RCA cable for connecting studio monitors. The DAC is fine, though. The sound is nice, just a little bit quiet.
All in all, I don't regret the purchase. I totally knew what I was getting when ordering. If you need something more serious you should look elsewhere (and invest more).
