well that's to be determined. Anyone that is into the ART of turntablism will disagree that you can scratch with a midi control. And I too will agree with them. I have been scratching for three years or more and the difference between actual vinyl and midi control is vast. it may not seem so to the untrained hand but to a weathered DJ who knows the feel of a analog vinyl to that of a DVS is a whole different world. You will know if scratching is your thing and if so then you will have to go Vinyl.
For example........ Someone on FP posed a wicked awesome thread with 52 MP3 versions of Scratch records. I have them and I practice scratching everyday. I will scratch with my vinyl for 30 minutes and then try beat juggling and scratching with the DVS ( using any of the 52 mp3 records) the response with the DVS is good, but not anywhere near as good as the analog. I can FEEL the difference and its huge to me. If I had learned to scratch with the DVS system I would only be able to scratch half as good as I can now. There is a Big difference is the bottom line.
So from the Jester if you wanna Scratch and that's your thing GET DECKS
otherwise you'll be a hack
