my old midi keyboard connects with a normal midi lead to the PC through a Creative front panel. Some of the keys now don't work after storage. I've been offered a usb midi keyboard. has anyone experience of them with PT 2013? Its an Oxygen 49. if it had a standard midi output i'd be happy but i don't know at this stage and i also don't know if there are added benefits of using usb - a more 'modern' interface!
