OK, so I guess forget about the CASIO board and OMB. Too bad.

I just downloaded the OMB and tried playing it using my pc keyboard and the cheap built-in internal sound card. It was awkward and sounded bad but I was able to make a song in a few minutes and recorded it in a midifile.

Now, if I buy a midi cable and hook it up to my PSR2000, will it sound much better or at least sound like my PSR2000 built in styles and voices ?
