I know this is a common question but I cannot get it to work... I have a Yamaha PSR170, Windows XP and Realtek AC97 Soundcar. When I plugged my keyboard to my PC the MPU401 driver installed Well, the thing is, if I open a midi file, I can hear it in my Yamaha Keyboard but... I cannot record songs from it!!! I've tried a lot of different programs but I get the same results: Output Works, no Input Signal... what can I do?? I use a normal midi cable plugged in the Joystick thing in my sound card. Please, could someone help me???
