I would like to announce the public release of the first gx_head release candidate. gx_head is a derivation from the guitarix project and provide a simple guitar amp head interface, a tuner, a mono rack and a stereo rack. In-build effects can un/loaded to the racks,reordered and saved as presets. All Controllers provide a MIDI learn connection via JACK MIDI Presets can switch/load/unload with the MIDI program change message (any channel). You found some screen-shots here: http://sourceforge.net/apps/wordpress/guitarix/ check it out and let us know if you found a bug, get it here: http://sourceforge.net/projects/guitarix/files/gx_head/gx_head-rc.tar.bz2/d… greats hermann
