Thanks for all the replies everyone, looks like I have plenty of options after all.

I like this one: http://www.sweetwater.com/store/detail/SLmk2zero/

So basically I dont want any software. its gotta be a physical device such as the above that plugs into an arranger like a PSR or a Korg PA and I can use it for a wealth realtime controls to style parts and Right1, Right2, etc etc

They all seem to be well reasonably priced too.

thanks
