The PSR-E363s USB connection carries audio and MIDI data simultaneously, and the driver needs to be able to understand the data coming through the USB connection. I think the Steinberg driver is for both USB-audio and USB-MIDI, while the Yamaha driver is for USB-MIDI only. Then I wént to the storé Ive bóught it and tóok my notebook ánd cables to tést other YAMAHA KEYB0ARDS (E463 and another E363) with the same results Ive got at home. The MACBOOK instaIls the drivér but not détects the YAMAHA KEYB0ARD as MIDI dévice. Then Ive instaIled the Yamaha Stéinberg USB Driver ánd It appears át the SOUND (C0NTROL PANEL) as bóth playing and récording tabs. When I run the USB-MIDI Driver V3.1.4 for Win 108.187 SP1 (64-bit) (latest version) it stops with the Error 25001 - (no device (hardware) found.
