sfmans: "No, of course it doesn't, it's aimed at complete beginners to give them assistance in their first steps on the instrument".

RE: I have a rather different view on that. I can't see why the issue concerning management of the bellows including adapting reversals to musical phrasing would not be part of the objects for any beginner. Using the bellows with squeezeboxes is what using the lungs is for a singer or a player of wind instruments. As a matter of fact I mean that it is a severe mistake NOT to start out playing a squeezebox by information and training of "bellowsing". The majority of old concertina tutors hardly even mention the topic except saying that the "bellows should be activated in a straight line" or similar things.

You say:"Bellows direction, other techniques to facilitate emulation of the punchy anglo style (which inter alia is not necessarily the effect that everyone is always aiming at...."

RE:It is not only for "punchy style" that bellows reversals are essential - ALL more sophisticated articulation of tone IS a matter of bellows control. All you can do with your finger is starting and stopping a choosen pitch.If by any chance you might have missed my earlier nagging, there are a few clips at Youtube...:-)
