Doron,

Thanks, and a very happy new year to you.

I don't know what Technics model you have, but on the KN-6000 and 7000 you can easily change all the settings of the instruments and the drumkit of a style by selecting "sound arranger-set". After you made your changes the settings will be memorized and everytime you select "sound arranger-on" it will recall your preferences on each style. Works like a charm!

Good luck!
