Hi Bob,
Thanks for that - It's more or less the same translation which I achieved...... As usual, On-Line translations rarely give a true meaning of the text..... I think you're right about the 'colors' referring to the voices.

I've just had a look at the specs. for the two keyboards and they quote the KN6000 having 1008 voices and the KN6500 having 1065 voices, so the KN6500 had an extra 57 voices. I expect that these will be the voices which are undefined in the KN6000 def file.

I've had a look on the internet for the KN6500 'Blue Book' but was unable to find a copy - plenty of User Manuals but no mention of the 'Reference Guide'.

I wonder if any KN6500 owner would be willing to scan the guide - or just the MIDI pages, so that I could send them to our Polish friend ???

Hope you're keeping well Bob and still bashing the Pool Balls
