Boyaka2000, I was where you were when I first bought an MV. I found the workflow cumbersome, the build quality questionable, operations slow, and the thing was just ugly.
Fast forward three months, and what a turnaround. I now find its workflow unbelievably fast and intuitive, the build quality top notch, the operations lightning fast (except loading projects, of course!), and the thing is just the sexiest thing I have seen.
The difference? Taking the time to read the manuals - 3 months, mind you, discovering workarounds for its minimal bugs compared to any Windows or MAC based DAW and a few other Zoom standalone multitrackers, and simply giving myself time to get used to the workflow.
I made the mistake of assuming that the best machine was the one that would be easiest to use right out of the box. WIth that criteria, the MV blows. But change the criteria to determine that the best machine is the one that will serve you best once you truly learn how to use it, and you may find like I did that the MV stands alone.
As far as comparing it to the MPC, I'd say that's the closest competitor, but the 8 stereo audio tracks and VGA GUI of the MV give it the edge over the MPC's 8 mono audio tracks and lack of VGA GUI. (Not knocking the MCP by any means)
Peace!
