Thanks for chiming in, Quetscher. Do you mean bellows tape? I don’t see how bellows straps (as I see them on the site and in a Google image search) would be used with a melodica.

I was thinking during the night (why waste time sleeping) that if beeswax were applied to the gasket, that would preclude alternative solutions to the problem by the way in which it would compromise the gasket.
