Hi,
I suggest you choose one of your preset polka styles for that Tony Bass song. Most are suitable for that song. If you want to get closer to the original sounds you could mute some of the voice parts of the style and/or try to change the voice of a style part to a 60s combo organ voice.
Since you posted this in the Genos section I assume you own a Genos.... In that case you could also try the style called AnimationFantasy which can be found in your Movie&Show style folder. Again, play with muting parts and combo organ voicing
good luck,
Peter
