This won't probably matter to many experts here but I also want to say I'm extremely happy using my set up with a Psr s900, Korg pa500, TR 61, Roland Pk5 pedal plus the Mediastation altogether. The MS allowed me to keep adding high quality sounds and to link the different parts/channels of all my keyboards so easily. I' ve been able to play one orchestral VST simultaneusly from the three keyboards layering sounds from all the sound engines. That's incredibly beautiful.
