All the styles using I've tried in band in a box use the same tired accordion sound which is the bandonian. Sometimes a waltz for example needs just a single reed.
Scandanavian styles are completely different from German waltzes. The Germans tend to use a wet tuned reed
( musette ) A point the bosses here should take into consideration.
The French only use the Bandonian reeds for certain dances, Scottish players like myself only use them for 2nd accordion work.
Lesson over for today.
