Keyboard-strokes and MIDI-learn
Many actions in guitarix can be controlled using keyboard-shortcuts. Switch presets by calling them directly with hitting the number of the preset or by pressing up/down on your keyboard. Effect-modules are available with single strokes to respective characters on the keyboard.
Turning a knob with the mouse-pointer is okayish but to turn a real, physical knob to change a value for an amp is better. Connect guitarix via Jack-MIDI with any generic controller-interface. A simple middle-click on any of the controls in guitarix pops up a dialogue in which you can connect any switch or knob or slider on your interface by simply moving it and hit OK.
Since the MIDI-connection is independent from GUI-interaction you do not need to touch your mouse or keyboard on stage -- with your MIDI-interface at your feet guitarix is always under your control.
Ready for complete convolution
Thanks to the great work of Fons Adriaensen on zita-convolver guitarix offers you the opportunity to convolve your sound with thousands of impulse-response files to be found on the internet or with IR-files you produce yourself.
Make your guitar sound as if you play it in a cathedral, in a concert-hall or in your very own kitchen. Since there are IR-files taken from speakers or amps out there, you can also use the convolver to make guitarix sound as the exotic vintage amp, you have tried to catch on ebay for years.
Make your own with ease
To modify an amplifier is easy: just get a set of tools, buy some parts, unplug the power line and open the housing. Now you can stick in new tubes and speakers as you desire...
In guitarix you can do the same without the tools: a few clicks in Menu/Tube let you choose from 12 variations of tube-emulations and you may also choose among several tone-stack emulations and virtual speakers as well. As well as any other settings you may store all this in presets, that can optionally remember your MIDI-connections also.
Though you will find a lot of well-known names among these modules, we do not pretend to imitate a real, physical amp. Some of our modules sound pretty close to well known originals, we took a lot of time and care to provide you with the characteristics of popular legends. But we still see guitarix as an amp in its own right. It sounds the way you set it up and you are encouraged to try the wildest combinations to make guitarix your very own personal amplifier.
And there is still more...
guitarix comes with a tuner that looks and acts as a high-class analogue tuner.
To visualize your gain in detail call meter bridge from Menu/Options. It will be automatically connected with the in and output from guitarix.
Set up and connect
Guitarix runs with Jack under Linux(or any other UNIX it can be built for such as MacOSX). So consequently you need a working installation of Jack in order to use guitarix. Jack is easily available in all major Linux-distros, just install jack audio connection kit using your package-manager(Synaptic, YAST, yum, apt -- you name it). We recommend that you install the graphical Jack-remote-control qjackctl (Qjackcontrol or simply Jack-control) too.
Guitarix will check at startup, if Jack is running and it will help you to start it, in case it does not. But we recommend that you start Jack using Qjackctl before you start guitarix.
These settings are sane for a USB-interface and a moderately modern system. Adjust as desired and check, if you get dropouts(xruns).
Once Jack is started you may start guitarix, it will show up some in/out-ports in the connection-window of Qjackctl:
The connecions window of Qjackctl shows all running applications that are compatible with Jack. How many depends on the resources of your computer. All can be connected to each other as your wishes dictate ;-).
Find out, which system capture-port(left column) your guitar is connected to and connect this one with gx_head_amp in_0(right column). The output port of gx_head(left column) should be connected to gx_head_fx in_0(right right? ;-)).
The 2 output-ports of gx_head_fx provide a stereo-signal processed by guitarix. Connect this one to system playback and hear your signal screaming throughout the neighborhood.
In the world of Jack this is not all you can do. The outputs can be connected to a track in a DAW like Ardour or Qtractor to record your playing in real time. You can also choose to record the mono-output of the amp to capture a signal not processed by FX, so you can apply FX from plug-ins in the track of your DAW and change their settings to fit later mixes without the need to re-record. And all this still with the fun to play a signal that is enriched with spices like flanger or feedback-delay.
Guitarix amp connected to Rakarrack, you can record/hear all 3 signals at the same time: gx_head_amp vanilla, processed by gx_head_fx and processed by Rakarrack. AMS and Hydrogen can deliver synth-sounds and drum-patterns at the same time as well.
