fat1.lv2 - AutoTune-1

fat1.lv2 is an auto-tuner based on Fons Adriaensen's zita-at1.

See zita-at1's quickguide for an introduction.

The only differences to zita-at1 is that the plugin reports its latency to the host, saves the state with the session and the MIDI input has sidechain semantics.


Compiling fat1.lv2 requires the LV2 SDK, fftw, gnu-make, and a c-compiler.

  git clone git://
  cd fat1.lv2
  make submodules
  sudo make install PREFIX=/usr

Note to packagers: The Makefile honors PREFIX and DESTDIR variables as well as CFLAGS, LDFLAGS and OPTIMIZATIONS (additions to CFLAGS), also see the first 10 lines of the Makefile.
