GNX4 FAQs

Can you make a hypermodel from a hypermodel?
Yes, you can. Once you have created a hypermodel, it can now be selected as either a red or green amp and combined with another amp to create a second generation hypermodel.
Why is modeling cool?
Modeling gets you as close to the sound of your favorite amp without actually having to own one, thus saving you thousands of dollars and lots of space.
How is modeling limited?
Modeling is essentially an endpoint. Any given amp model offers a specific sound
with limited control over that sound.
Do GENETX products still do modeling?
Yes, they do. Each GENETX product has factory based models of popular modern and vintage amplifiers.
What does the Warp control do?
The Warp control allows you to combine the characteristics of any two amp models in varying ratios. This resultant ratio can then be saved off as a new hypermodel.
How many hypermodels can I save?
The GNX 1 allows you to save off 9 user hypermodels within the GNX1's internal memory with the GENEDIT Computer Editor Libarian software you can save off as many hypermodels as your hard drive will allow. These can then be imported to the GNX as needed.
Isn't Warp just pan or a crossfade?
No, warping extracts the characteristics of each amp and combines the two into a completely new sound. Whereas panning or crossfading simply increases the level of one while decreasing the level of the other, while not actually combining their actual characteristics.
What is cabinet tuning?
Cabinet tuning is as if you actually changed the size of the cabinet and speaker system's physical dimensions, making it larger or smaller. This changes a cabinet's response and resonance characteristics.
Can a I warp between 2 amps in real time?
Yes, This can be done either via the expression pedal, internal LFOs, or MIDI CC control. There are three different ways you can warp: you can either warp between amp models only; you can warp between speaker cabinets only; or warp between amp/cabinet combinations.
How does the GNX differ from the Genesis?
The GNX is designed primarily as a live performance system and the GENESIS 3 is designed primarily for recording. Although the GENESIS 3, with the optional foot controller, can be used for live performance as well.
Can I use Genetx products as a multi-effects?
Yes, every GENETXs product is equipped with a vast library of studio quality effects.
When I create a hypermodel does it sound good?
We're confident that the combination of any two amp models will produce exciting new sounds and we absolutely encourage you to experiment. We also invite you to join our online community of users in sharing your creations with others.
After downloading updated firmware, my unit shows "TOE DOWN" in the display, what do I do now?
TOE DOWN represents a prompt to calibrate the pedal. Rock the expression pedal all the way in the forward position and press the footswitch that is flashing, (On GNX2 this is the EFFECT footswitch, on GNX3 it is the CHORUS footswitch) The diplay will show "TOE UP" Rock the exression pedal back towards you and press the lit footswitch (Delay) It now shows VSWITCH, push the pedal forward and put pressure on the toe, then back the pedal off again.
What is the hard reset and pedal calibration for the GNX4?
Unit off.
Expression pedal in the half-way position.
Press and hold Output Setup button.

Turn on the GNX4.
When Reset ? appears in the display, let go of Output Setup, then press/release the Mode button.
When display reads Toe Down, put the expression pedal down.
Press and release the flashing footswitch.
Toe up appears on display. Bring pedal up.
Press and release flashing footswitch.
V switch ppears in display. Put pedal toe down, apply pressure until display reads 50.
Press Exit.
How do I connect my GNX through the effects loop of my amp if I only want to use effects and not amp modeling?
To connect via effects loop, connect the send of the loop to he guitar input of the GNX, and connect the left 1/4 inch output of the GNX to the return of the amp.

Next, select a preset on the GNX, and in that preset put the amp model and the cabinet model on DIRECT. Press the Utility Button, go to the target system, and put that on DIRECT or FX4x12.
I can't get mp3 files from my compact flash card to play through the GNX4 out to my amp.
Import the MP3 files into Protracks and Reencode them by selecting
file>export>audio and name them with a .mp3 extension
I can't seem to load my USB drivers.
You will need to uninstall the USB drivers in the device manager, go to control panel, system, device manager, sound video and game controllers, and click the plus button, verify the GNX4 is connected and turned on. Uninstall all 5 digitech drivers or USB audio devices. Verify you uninstall the correct drivers. Call 801-566-8800 if you are not sure, and we will help you! After you uninstall the drivers turn off the GNX4 unplug the USB cable from the GNX4, Perform a factory reset on the GNX4.
This procedure is in the manual. Reconnect the GNX4 this is a very important step, Watch your computer screen on the bottom right hand corner, it will say found new hardware then you will get a lot of pot up window, wait until the last one says Your new hardware is installed and ready to use. Now put the X-Edit/Librarian disk into your computer, Run the USB midi drivers, follow the GNX4 software installation guide.

How do I put material that is in ProTracks back on my CF card?
You will need to go to file>export>audio for EACH track of the song,
>(hightlight the track, then go to export) and export it into a specific
>song folder in the GNX4 Songs folder. Export it as a RIFF wav file.
What are the primary differences between the GNX4 and the GNX3?
The GNX4 uses compact flash cards for memory, giving you up to 2gig capacity which is around 6 hours recording time. The GNX3 uses smart media cards, giving less time. Also, the drums in the GNX4 are much better, and the GNX4 will play mp3s, which the GNX3 will not do.
The GNX4 provides phantom power for using condenser mics, and the GNX3 does not.
I can't get any audio input using MAC OSX and Bias Deck.
