Hi list! I've been looking at the Roland V Studio 700 C and really can't figure out which model that will work with my machine with Windows 7 64 bit and Sonar with CakeTalking 8.5. So my question to you all is if someone has any advices of which control surface I should choose? Maybe there is another model from another manufacturer that you consider better? The price is not an issue at this point of research for me. Best regards, Erik Bryndahl
