Hi Walter,
I had the same problem. I'm not allowed to keep 2 keyboards in the living room either. I was lucky my hubby even allowed me to put the KN7 hidden away in the corner.

I still ended up keeping my PSRPro ( in a spare room), even though I never used it after I got the KN7. Worth next to nothing second hand, I decided to keep it.

Now that I discovered the audio functions on the KN7, I'm really happy that I did keep the pro. In a nutshell, I record the PSR as an audio backing ( instead of as a midifile) save it to the sd card, plug it into the kn7. and play along. ie backing track with psr voices, melody using KN7.

In short, I don't have to keep both keyboards in the living room.

best wishes
Rikki

p.s. Do you belong to the PSR Yahoo style group, they're a nice bunch also.
