Yes, Gunnar, Kn5000 owners have been smiled upon by EMC/Taiyo.

Unfortunately the 5000 convert disk does not work on the 6000/6500 because the 6000 program has to take into account the extra 10 patterns in each individual composer compared to 5000 format. I do not recommend you try it... you will crash your 6000/6500.

Still €25 is not too expensive if you have a lot of Yamaha styles you can use.
