Louigi, just as general comment, I don't think that your opening gambit is correct. If anything, I would suspect that there is a greater percentage of what you term "electronic musicians" as contrasted with "acoustic" musicians among those who use Linux than there is in the general population of musicians, or even musicians who use computers. However, in all these communities, the number of "electronic musicians" is smaller than the number of "acoustic musicians" in absolute terms. Thus, when you start exploring the Linux audio world, you run into a lot of people using non-electronic instruments, but this is no different than if you were to start exploring the world of "people who make music" in general.

In addition, I think that you already know that you have a fairly particular definition of "electronic musician" that actually excludes a lot of the electronic music composers and performers who have traditionally found Linux to be fairly hospitable place. These are specifically people who are not in search of new synths or FX units with which to play relatively conventional compositions with (perhaps) rather unusual timbres, but instead want the control and possibilities presented by tools like SuperCollider, PureData, Common Music and so on and so forth. I don't think that one group is more important than the other, but I do know how labels can be a problem, both in terms of a reduction in cognitive distinctions and also in social exclusion.
