You are losing me in translation somewhere….
1. Hook keyboard to pc using midi to usb convertor or usb to usb depending upon your keyboard, you may or may not have to install asio4all
2. Install synthesia
3. Find a midi file, or create one
4. Run the midi file with synthsia (it will give the graphics on screen, no audio)
5. You play your keyboard to match the graphics & this plays the music, the midi converter is what tells the pc what keys you are pressing on the keyboard
6. If you want to capture the performance with your HD60, you can do it before step 4
Midiculous is just another software package geared more towards official piano tutoring, where synthesia can still be used as a typing tutor but is isn’t as good. Some kids may respond better to a game environment at first.
