AVTechNO! is definitely an awesome producer, but I wouldn't be so quick to dismiss others based on that fact. Kikuo, HSP, and Wowaka are all awesome producers as well, each with their own distinctive style.
I never said anything about other users in that way, I just said most of what I've heard hasn't been very good. That isn't to say everything is terrible or the quality of music is in any way similar to the creator behind it. On that note I've just got into SeikoP who's made some fantastic stuff using Luka a lot.
@Seasonreaper Indeed, I can't deny that AVTechNO! is really awesome. However, I don't totally agree with you, I think It's not acceptable to say that most producers are just a bunch of loser, you know there are a lot of great unknwon producers ... I guess, everyone and each one has just his own style.
I agree with most of the comments here. There isn't anyone else I've heard that's this good with Vocaloids. In fact, most stuff that uses Vocaloids ranks between mediocre and painful. This guy, on the other hand, is fantastic.
