If you are used to scratching on Vinyl, using a controller can take a lot of getting used to. I can scratch, but find it very difficult to pull off the same tricks on a CDJ or controller. The reason for this is a few things, slipmats/vinyl friction and the controllers/CDJ’s are not the same size. However scratching on Serato/TCV is a lot easier than CDJ’s & controllers, as I learnt to scratch with Vinyl and it feels pretty much the same.
I’ve used a few different controllers and I just don’t feel it. I think this is because I come from the daze of Vinyl, I just don’t get the same buzz with controllers, but it does mean you can add a few more elements, such as live remixing and 3-4 deck mixing which is a lot easier with digi stuff.
It has come a long way from a 2 channel mixer & two turntables and I think it’s great it has progressed the way it has.
ac505 if you can, try out some different systems there might be one you prefer.
