On another point - never use the bellows to produce punch to your notes, the reason that bad Anglo (and melodion) players sound bad is that they use the bellows to modulate the reeds. Good players use the buttons to modulate the notes, that way they have control. The real trick to producing punchy music is to cut notes off short - it's the end of the note that produces punch, not the begining.

yes and no,finger attack is important,but the reason anglos are punchier is because of bellows changes,so the two techniques are equally important.
it is aquestion of finding the appropriate place to change bellows.
