No, the files in the tarball say "or later".  Sorry about that.

Indeed.  Unfortunately, GPLv2-only is actually correct.  The file
headers all say

  ams is free software: you can redistribute it and/or modify
  it under the terms of the GNU General Public License version 2 as
  published by the Free Software Foundation.

I contacted the author to ask if relicensing is an option, but it seems
that at least two more authors are involved.

Luckily, AMS could also be built against clalsadrv, the deprecated
predecessor of zita-alsa-pcmi.  I'll package that up and replace the
input for alsa-modular-synth.
