I'm happy to announce the first public release of gx_head. 
gx_head is a simple guitar mono tube amplifier simulation based 
on the work we have done in the guitarix project. 
gx_head provide 3 tube models (12AX7, 12AU7, 6V6)
and 8 different tonestack models(Bassman, Twin Reverb, Princeton, JCM-800, 
JCM-2000, M-Lead, M2199, AC30), so you can simply create the amp-model 
to your needs.

gx_head comes with a bunch of in-build effects, like distortion, crybaby, 
autowah, phaser, flanger, echo, delay, . . . 
The effects could ordered in two Racks, on for the mono effects, witch
could be load for pre or post processing, and one for the stereo
effects, witch could only used in post processing.
Effects are loadable over the menu, a pop-up menu in the racks, or a
plugin bar. Settings could saved/load as presets. 
gx_head comes with some factory settings provided by guitarix/gx_head
friend "funkmuscle", thanks therefore.

All UI controllers could connected with jack midi via MIDI learn with
your external MIDI controllers.

gx_head is ready for language support via gettext() and comes thanks to 
Pablo Fernández with a Spanish translation.

The style file gx2 is contributed by zettberlin, thanks Hartmut

For extra Impulse Responses, gx_head uses the 
zita-convolver library, and, 
for resampling we use zita-resampler,
both written by Fons Adriaensen. 

We use the marvellous faust compiler to build the amp and effects and will say
thanks to

         : Yann Orlary 

For faust users :

All used Faust dsp files are included in /gx_head/src/faust, 
the resulting .cc files are in /gx_head/src/faust-cc 
The tools we use to convert (post-processing and plot) 
the resulting faust cpp files to the needed include format, 
stay in the /gx_head/tools directory.
