Hi Gunnar . Looking forward to your (unbiased ) review of the KN6500. The primary reason I never upgraded to it (from my KN5000) is because the KN6500's (optional but essential) HD-SX6 hard drive STILL cannot be backed up to an external PC. This is VERY disapointing. Keysoft Service (makers of the hard drive & hard drive software) have been promising a software fix for MANY months now, but still no news. AT this rate, by the time Keysoft comes up with a software fix, the KN7000 will be out (and hopefully INCLUDE a Technics (Panasonic?) proprietary hard drive with the keyboard. Afterall, hard drives have been dropping a lot in price recently, so the cost of INCLUDING one in an arranger keyboard (including hard drive backup & management software) should be pretty minimal. - Scott
