Hi Hannan,

The easiest way to backwardly convert a KN5000 style to a KN2000 style is using one of the "EMC Style Converter" software programs available in your Country (Germany) from Tastenshop, The results of the conversion process may not sound quite as good as the original so you may need to do some minor post tweeking of the sounds to get the results you are after.

Good luck,
