You don't
have to play the patterns if you don't want. The pattern track can be stepped in, placed by location, or played in real time like drums alongside the MIDI and audio tracks in Song Mode. The Pattern Event screen tells you what is where and every pattern can be auditioned from a labeled pad. Most important is that Song Mode between the MV and MPC are hugely different and it's a matter of individual preference. However i also respect that it isn't for everybody. Personally I like the flexibility being able to do more than just stringing patterns. The above mainly for those unfamiliar with the MV's song mode vs. the MPC list.
If you sell your MV now there is no short supply of brand new units on Ebay from small scale sellers with little or no overhead. Prices are as low $1700 new. There's usually no 30 honeymoon but if your sure that's what you want it's a pretty sweet deal. This recession is taking it's toll on gear makers making it a unusually strong buyer's market.
One thing that really pissed me off about the mv is loading a patch, you gotta go through menus and sub menus before you can even get to view the damn patches
Then just move the favorite folders to higher position in the directory or place your most used patches on the root directory and they'll be on the first page when you hit Import. better yet just make a new folder on the first page and move and save patches to it. Just because Roland nested a folder doesn't mean it has to stay there nor do you have to save them there.
