[Harp-L] Will chromatics one day be valveless?

[Serguei Volkov <svolkov@xxxxxxxxx>]

Hi,

Now that I've introduced myself, please allow me to ask
one first question.

This is a question to people from Hohner, Seydel, as well
as the custom harmonica builders.

Has there been extensive research on a valveless harmonica
design (i don't mean Koch or Seydel standard)? What I mean
is have there been efforts made to create an airtight slide
mechanism, which would render valves unnecessary?

I suppose there have, because it seems such a natural issue
to address. Is there a fundamental flaw in this concept?

Thanks,

Sergei
