Control Surface for iPod touch by Propellerhead
Why not do a cool little app for the iPhone or iPod touch where by people with reason 3.0+ (version I bought) can use sliders, a keyboard and some nobs and drum pads depending on what menu option you use to control Reason via wifi. It would be a really cool Korg Kaos sort of surface with multi touch so you could do drumming and mixing from other rooms if need be. Say a singer in a booth could alter volume etc. Just a thought, I'd pay up to 60 dollars in the iTunes apps store for this baby.
