Making Music with FOSS + OT: Ardour might be able to be a host for MacOS plugins, e.g. a Vocoder

[Ralf]

Oops, this effect they use for synth, not for vocals, don't get me
wrong:

"What I do like is this portamento-pitch-bend-effect they do use for
every song in the charts (seldom the way they use it), perhaps auto-tune
too?"

I anyway would use it different.

And, Ardour for Linux seems not to be able to be a OsX plugin host.
