Klangsynthese v0.2.1

This release updates linux device loading logic. See 21b3409 for detailed notes.

Klangsynthese v0.2.0

This removes the dependency on libalsa / alsa packages on linux.

Klangsynthese v0.1.1

The maker of the alsa-go library hasn't updated it for new standards now required in go 1.12 (and probably set a long time ago) so this update uses our own fork.

Klangsynthese 0.1.0

I am relatively arbitrarily declaring that what we have so far in the library is v0.1.0, for the benefit of vendoring.
