What kind of USB cable do I need to connect PX-150 to a PC for recording and as a controller? Is there a special USB cable for connecting digital instruments to PC? How long can it be? I read something about Yamaha P-105 that the cable has to be under 3 meters. Is this USB cable good? Hama USB 2.0 gold-plated https://ro.hama.com/portal?action=2563&articleId=30050113 And I understand that I need a lighting to usb cable to connect it to an iPad 2 tablet. Could you recommend one? Thank you!
