I'm looking into getting a keyboard/MIDI controller just to add some synth (background strings and stuff) and other sound effects to my recordings. I'm not really a keyboard player, but I just want something basic to accomplish this. Anyone have any suggestions on a decent keyboard (while on a budget)? I've seen some M-Audios. I'm working with Cakewalk music creator, which comes with Dreamstation DXi soft synth and ACID-format audio loop library. Could any controller work with these? Thanks
