When you say “hardware”, have you considered an Ipad with appropriate software? I’m using an Ipad with Lemur and have designed my own layout and it’s by far the best controller I’ve ever used (and I’ve had just about every controller aside from the Eucon series). Not only does it control Cubase but acts as a midi keybaord controller and controls my entire studio monitoring via RME Totalmix, all on one screen.
