In all honesty the MV is overblown and has more stuff than I actually need. I was pretty much fine for the most part with the 2500, the MV adds a couple more nice convenient features that are very useful. But I can tell that there is a huge bulk of it that I will probably never use.
The main selling point was the price. I felt like I was being cheated as the MPC 2500 (and MPCs in general) are waaay overpriced. For the money I was paying, I felt as though I might as well save my money (as I actually ended up making money by selling my MPC and buying a used MV) and get the bigger machine with more features. I was also unhappy with Akai's support of the 2500. Their updates stink and they are cheating honest dedicated customers. The JJ OS was my only reason for even holding on to it for as long as I did. At least with the MV I can have a little more confidence that they will only add to the OS and strive to make their customers happy.
The most annoying thing about the MV tho is the midi situation. At first I thought I could probably live with 2 midi outs but now I realize that I am constantly wanting to build up my production set-up (yes I am afflicted with gear lust). But at the same time it is a hidden blessing as it just gives me another reason to not buy more gear Dawg, now u talkin reckless. How can a piece of equipment be overblown by having to many feature and capabilities?? If u wanna be stuck back in time and limit ur possibilities, get a set of turn tables and call it a day. Realize the music industry is forever evolving and it's up to the artist/producer/engineer to step their game up and get in where they fit in. There's a reason why the MV is packed with features, so u have room to grow in your sound. Why else does Akai multiple MPC's and Roland just two MV's(basically the same)?? Akai had to put out numerous models to stay in the race with the MV. The MV shut the game down the same way OpenLabs Meko/Neko took over workstation all-in-one platforms. Check out the RZA on YouTube talking about the MV verses other platforms to include the differences of software. But once again, it all depends on what the user feels most comfy with, plus what ever u get, u need to learn it thoroughly.
