Kawai Synthesizers

Wow! Nobody has posted anything since May???
Does anyone know the exact details of the ram cards for this K4r 
synth module. I bought one from an auction and will get it soon. I 
should be able to edit the patches with my Unisyn program. Also I 
see that JSynthLib (free) has a K4/K4r editor now. This will be my 
7th synth module (mostly Roland and Yamaha). I seem to be able to 
find these ram cards for 35 to 40 bucks from surplus suppliers but I 
don't know enough of the details to know if they will work for this 
box. I may even have the batteries for the cards. Any help would be 
appreciated. Thank you, Narfman - Narfland Studios
