I recently got my KP3 and I decided to buy a 4gb sd card for it when I press shift+1 it says on the display "error". I plugged it into the computer and it only said "KP3 not found".
Im having the same problem! I have a 16GB SDHC and i keep getting the ERROR message. I read the manual for the Kaossilator Pro many times and it said the capacity for a SD card is 2GB but for a SDHC card is up to 32GB. Can some one please tell me what the problem is?
