Is anyone using this program with their PSR's..? I was very fortunate to aquire this program today... I want to use it with my PSR-550. Here's what I want to do.. Will this program allow me to make backing tracks, and then save them as midi files and play them back through my PSR-550? If so how will they sound? I will be playing at a function in a few weeks and I would like to be able to make some midi files with this software so all I have to do is sit down and play the keys..... It's a short function so the music is really just for background noise...

Thanks,
Squeak
