Interesting, I am not really a keyboard player, yet lol. I just picked it up to make life alittle easier in sonar. I wanted it for vsti control more than anything. I haven't had a drum pad controller or midi keyboard before, so I figured that the Akai would be a good start. I have heard that the sennheiser hd280 cans are pretty good sounding, I want them mostly for the iso factor. I have a set of akg k44 cans now, and I can't hear my tone going in when I am playing guitar mic'd, to loud. So I was hoping if these can cut some of the amp out so that I can tell how well I have my mic placement they would be very worth the 100 bucks. If not, at least they may help cut out some of the bleed I get using the MXL 990 on vocals. The K44's bleed like a stuck hog, if a stuck hog bleeds alot lol. I am really curious as to how well that ART MP V3 improves my quality. I do alot of vst amp modeling DI, and the tascam us800 I have sucks for that purpose, and the ART can also be used for a DI box so I am hoping it will simmer down the levels alittle and make life easier for amp modeling and bass DI. I will give you guys an update soon, my new gear should be here tomorrow, I will probably check it out, but this weekend I will be putting the gear to work. Hopefully I invested wisely, you never know, reviews are normally very biased, either people hate something or absolutely love it. Not to often is it said, "It works for me, does it's job good."
