I really like the concept of the Controller 1. You can select 8(?) different pitches without getting your hand off the Vinyl, therefore you can make those pitch-changes so fast that you can actually use them as a new additional technique as you don't lose the control over the Vinyl or the fader while tapping those buttons. Furthermore it is far superior to the method of controlling the speed with your hand (at least for longer turns), as you can only maintain a constant pitch for about a half of one turn before the tonearm gets in the way or you have to change the position of your arm which makes it nearly impossible to maintain the exat same speed for one or more full turns. With the pitch control this won't be a problem anymore. But I don't think that the controller can replace classic instruments as you can only change the tune and the volume but are still limited to the "color" and all the other stuff I can't express in english which are after all determined by the sample you use and more or as important for the character of the music as tune and volume. Though it would work out fine for shorter sequences I think. If the controller one could also be used as a midi input too it could easily become the new high-end "standard", a pity it doesn't have this feature. I hope the whole thing will be released soon at a reasonable price (under 1000$), so that it can reach out to more people, which would help to establish the controller 1 and take away the "freaky" aspect some people (the one reviewer) joke about. one last question: Does the Controller one has a BPM detector?
