Hello,

I have connected a Yamaha S90 with an USB cable to my PC. After installing 
the drivers there are some midi ports available in Windows. Now I try to 
produce some sound from the S90 to my PC or I try to play a midi file from 
my computer on the Yamaha S90. But nothing happens at all.

My questions:

- How can I use the yamaha to send midi notes to my computer? (to record 
with an external program like cubase).
- Is it possible to send midi files  from my computer to the internal 
storage of the S90? (I also have a smartmedia card installed)

Thanx in advance for your replies!
