Create Digitech GNX4 Presets with MFX Supermodels

In this post, we’ll learn how to create Digitech GNX4 presets with MFX Supermodels. The MFX Supermodels are a software collection of amplifiers and speaker cabinets that were developed by a third party for the GNX4. Unfortunately, the supermodels are no longer commercially available, but sometimes you can find the CD-ROM for sale on e-Bay or Reverb. Using the Digitech X-Edit software, it’s easy to create your own presets with the MFX Supermodels. Before we begin, X-Edit only works in the Windows operating system, so Mac users will not be able to use X-Edit natively within MacOS. So let’s jump in and learn how to create Digitech GNX4 Presets with MFX Supermodels.

If you don’t have the MFX Supermodels available , but you’d still like to learn how to modify the stock GNX4 presets, have a look at my post Edit Digitech GNX4 Presets with X-Edit.

What You’ll Need to Get Started

  • The MFX Supermodels disc
  • Microsoft Windows. Windows 7, 8 and 10 work correctly.
  • Digitech GNX4 unit with a USB cable connected to your Windows computer
  • Digitech’s GNX4 drivers (v2.1) from the GNX4 product page
  • Digitech’s X-Edit software (v2.4.1) from the GNX4 product page

Create Digitech GNX4 Presets with MFX Supermodels

  1. Download and install the GNX4 USB drivers for Windows
  2. Download and install X-Edit. Remember, X-Edit only works on Windows
  3. It may be helpful for you to copy the entire MFX Supermodels disc to your local hard drive, or a USB drive. This is not a requirement, it’s just faster for some folks to not have to locate and load their cd-rom tray every time they want to access the files
  4. Make sure the GNX4 is connected by USB and power it on
  5. Open X-edit to begin editing. On the left-hand side, X-Edit lists the GNX4 preset banks. There is User, Factory and Memory Card, if you have a card inserted into your GNX4.XEdit-Main-Screen
  6. Expand the node of the bank you’d like to edit. Typically, you would edit the User or Memory Card banks to preserve your factory presets.
  7. Double click a preset name to load it into the window. I selected the first User bank preset “Hybrid” as an example.
  8. Now let’s see what the MFX Supermodels can do for us. Click File>Load Custom GeNetix Model>Amp & Cabinet>Channel 1. You’ll be asked to locate the *.ACM file that contains the information we need to load. I selected the Engl Savage 120 as an example. Click Open to continue.Select-Amp-and-Cab
  9. Your X-Edit screen will update the Channel 1 section (dark green colored) and show you the amp and cabinet you just selected.elected-Amp-and-Cab
  10. Change what you’d like to tweak your preset’s sound in the Channel 1 sections. Your changes are not saved until you manually save them.
  11. If you want to add a different amp and cabinet to Channel 2, repeat the process. Or maybe you want the same amp and cabinet on Channel 2, but using different stomps and effects. You have many options here, so don’t be afraid to get in there and tweak PER CHANNEL. And don’t forget about the Warp channel as well.
  12. To save your changes, click the Device Menu, then Store Preset. You’ll get this dialog window. Make sure the bank is correct, the number position of the preset in the bank is correct, and give it a new name, if desired. Click Store and the edited preset is now on your GNX4 or your memory card.

Summary

We’ve covered how to create Digitech GNX4 Presets with MFX Supermodels in this brief tutorial. Presets are a good starting point that allow for your own customizations and to easily recall a specific sound quickly. Experiment with the User or Memory Card preset banks to see what you can come up with, or import the presets others have already made. Either way, you have a world of options available to make those presets sound perfect for you.

Use a Digitech GNX4 as an Audio Interface in iOS

In this post, we’ll learn how to use a Digitech GNX4 as an audio interface in iOS. The GNX4 will work as an interface in iOS and iPadOS with just about any audio application using the official Apple USB adapter and a USB cable. The best part of the GNX4 being supported is that there is no need for drivers. You read that correctly. The GNX4 is a compliant device and is supported with plug and play by your iOS devices. Let’s get started!

10 June 2020 – Written by Michael R. Myers #mykmyrs

Skill Level: Beginner

Recently on the Facebook Digitech GNX4 group, a member asked how he could use his GNX4 as an audio interface for recording with an iOS device. In all the time I’ve used a 2011 iMac with my GNX4, which supports the GNX4 without any drivers, I hadn’t considered trying to hook my GNX4 directly into an iOS device as an interface to record. His question prompted me to give it a try on my iPad Air 2 and I can tell you that the GNX4 is supported as an audio interface in iOS.

Before you continue, you must have an official adapter from Apple to use as the connection interface between the GNX4 and a lightning iOS device. This adapter, which costs around $40 USD currently, provides a USB port and an additional lighting port. The additional lightning port allows for powering the iOS device while a USB device is also connected. Do yourself a favor and buy the official adapter because the cheap ones on Amazon and EBay often are not recognized by the iOS device, and if they are, can fail to transmit audio.

Configure Your GNX4’s USB Output Source

You may need to make a configuration parameter change on your GNX4, depending on what you’re going to record in your iOS application. Are you intending to record the actual audio output from your GNX4 patch, meaning the guitar signal, amp, cabinet and all effects? Or are you intending to send a dry guitar signal to the iOS app and use virtual amps, cabinets and effects within the application? You need to make sure you have a clear understanding of “what” you would like to record, otherwise sending a full-effects signal from the GNX4 into iOS may end up being sent through iOS amps and effects.

To change your GNX4 USB audio settings, see my previous post here. For the steps that I list below, I wanted to send the dry guitar signal from the GNX4 to an iOS guitar application to make use of the app’s amp, cabinet and effects. To do the dry signal, I configured USB 1-2 to be “DRYGUITAR” on the GNX4’s configuration settings.

What You’ll Need to Get Started

  • Digitech GNX4 unit with a USB cable
  • Apple iPhone or iPad with Lightning connector and built-in headphone jack
  • Apple iOS version 13 (not tested on any other versions, but may work)
  • Official Apple Lightning to USB 3 Camera Adapter
  • headphones or stereo audio cable to plug into headphone jack
  • IOS guitar application, such as GarageBand – available free in the AppStore

Steps to Connect Your GNX4 to an iOS Device

  1. Connect your USB cable from your GNX4 into the lightning adapter’s USB port.
  2. Connect a lightning cable into the adapter for a constant power source.
  3. Connect the lightning adapter into the iOS device.
  4. Plug your headphones or stereo line out cable into the iOS device
  5. Power on your GNX4.
  6. Open your iOS guitar application. Set its input channel to 1 for the guitar input. Each application’s settings’ options will vary.
  7. Play your guitar and you should immediately see the input and output volume meters show signal. In addition, you should be able to hear the audio playing in the headphones.

Where To Go From Here

After I had signal in the iOS GarageBand application, I used a stereo headphone cable to send the headphone jack to my computer’s digital audio workstation (DAW) to record the iOS application’s audio output. This type of setup could be useful if you need an array of different amps for recording and you’d like to focus your work on the iOS device.

Summary

I didn’t expect the GNX4 to work as an audio interface to iOS devices due to its sheer age. I was pleasantly surprised that it worked with only a small parameter change for the USB audio and an adapter I already owned for my iOS devices. If you haven’t explored iOS applications for guitars, here’s an opportunity for you to give it a shot for a relatively small adapter expenditure. Good luck and make some great sounds!

What is a USB Audio Interface?

Without spending too much time here, an audio interface is a piece of equipment that provides a means to record your guitar or microphone as a digital sound into your computer. Audio interfaces come in many price points and offer varying levels of features. A typical interface connects to your computer with a USB cable and sends its audio over that USB connection. Many models will offer two direct inputs for either guitar, microphone or other instrument inputs with 1/4” cables. You can also use a headphone jack on the interface to hear the audio directly, without any latency.

The GNX4 has a USB interface built in, so it is already capable of sending its audio output to your computer easily. For Mac users, there isn’t any need to install drivers because it’s CoreAudio compliant. For Windows 7 and 10, you must install the Digitech drivers, located on the Digitech product page, before you’re able to use the GNX4 as an interface.

The GNX4 offers two channels of USB audio, each having a stereo pair available. Through its configuration options, you can customize which sounds and effects are sent out on the USB channels. A typical configuration I use is to send the full effects out on 1/2 and I send the mono dry guitar signal on 3/4. This setup allows me to hear the full amp, cabinet and effects on channel 1 and I also have the dry, unaltered sound on 3/4 so that I am able to re-amp it in my DAW if desired. See my previous post about configuring your GNX4 to send the dry guitar signal.

What You’ll Need to Get Started

Steps to Record with the Digitech GNX4 Audio Interface

  1. Install the GNX4’s Digitech drivers, if using Windows as your operating system.
  2. Make sure your GNX4 is connected with a USB cable to your computer
  3. Power on your GNX4.
  4. Make sure your guitar cable is plugged into your guitar and the GNX4’s guitar input jack.
  5. Open your digital audio workstation (DAW) software and create a new project. We are using Tracktion Waveform 11 free in these steps.
  6. Open your DAW’s Settings page. Set the Input Audio source as the GNX4 USB 1/2 channel, Set the Output Audio source as your computer’s speakers or studio monitors.Waveform11-GNX4_Input_Setup
  7. Latency is always a factor with external audio devices. Configure yours as low as your operating system will allow. This part may take some time and patience to get correct, so make a note for yourself for future recording sessions.Waveform11-GNX4_Latency_Selection
  8. Switch back to the project window. Create a new track. Set its input source as “Input 1”. To the right of the Input 1 setting, click the red arrow to enable recording. Finally, verify that Live Input Monitoring is enabled so you can hear your guitar playback.GNX4_Record_Track
  9. Press the R key to begin recording your guitar signal.
  10. Press the space bar to stop recording. If you’ve done things correctly, you will see the audio waveform of your signal that was recorded to the track.GNX4_Track_Recorded
  11. Press the W key to rewind to the beginning of the track.
  12. Press the space bar to audition your recording.

Where To Go From Here

As you gain experience recording guitars, you will want to get into the habit of recording a signal with all your effects along with a track of just the dry guitar signal. Having the dry signal is a great safety net and also allows for re-amping and using a copy of the source signal in new and creative ways.

To record the dry signal, see my previous post on the topic.

Summary

Now that you can configure Waveform 11 to record your GNX4, here’s to your success as a home recording artist. Have fun recording, and take the time to make multi-layered parts with different guitars or your guitar using different pickup switch settings. Using your Digitech GNX4 audio interface will be a great way to record your progress and also help with getting all those parts played correctly before you release your tracks.

Digitech GNX4 MIDI Drums Through Your DAW

Have you ever wanted to use your Digitech GNX4 as a MIDI drum machine from your Digital Audio Workstation (DAW)? Recently I was working on a MIDI drum pattern and I wondered if it would be possible to send a MIDI track from my DAW to the GNX4 to perform and record it. Typically I use one of several drum kit VSTs within the DAW to generate my drum audio, but I was looking for some variety in the drum sounds. The good news is that I was able to send the MIDI track from the DAW to the GNX4 and record its playback in the DAW. Follow the steps in this post to generate Digitech GNX4 MIDI drums through your DAW.

Skill Level : Intermediate

Before we begin, I use Tracktion Waveform 11 Free as my DAW. I have not tried this GNX4 configuration in any other DAW. If you used another DAW, and got it to work correctly, please let me know the configuration steps.I will gladly update this post, giving you full credit, so that we can help others get up and running easily on varied software products.

Dealing with Audio Latency

Latency is a factor in this configuration, so playback can and will be affected by the latency you are going to experience. Even at 16ms, the fastest setting I have available to me while working on my Mac, there is a small delay while recording the GNX4’s output. When you record, be sure to set some lead-in space before the start of your drum MIDI and also at the end of the track to pick up any audio trails of the drum instruments.

I initially got this configuration to work on my 2011 iMac running High Sierra. When I wrote this post, I was using my iMac booted into Windows 10. The latency values in Mac went down to 16ms. On the same computer, running Windows 10, my lowest latency was 256ms in Windows Audio (Exclusive Mode). That is a HUGE difference in combating latency while recording.

What You’ll Need to Play Digitech GNX4 MIDI Drums Through Your DAW

  • Tracktion Waveform 11 – while free to use, it does require an account at their web site
  • Digitech GNX4 connected to a PC or Mac via USB
  • GNX4 drivers, if using Windows. Mac users do not need any drivers
  • Ability to configure your DAW software for MIDI and audio inputs/outputs
  • Ability to configure the GNX4 MIDI channel and USB audio sources
  • MIDI files of drum kit instruments

Steps to Configure MIDI Drum Playback

  1. Create a new project in your DAW.
  2. Add a new MIDI track and name it “MIDI Source”. Create a MIDI pattern in the “MIDI Source” track, or insert one you have available.Waveform 11 - Create MIDI Track
  3. Ensure your GNX4 is powered on and connected to your computer via USB so that we can configure it as an input device.
  4. In Settings>Audio Devices, set your Digitech USB 1-2 as your input device. Set your speakers/monitors as your output device. Set your audio buffer as low as possible. 160 ms was the lowest I could set without Waveform telling me I was exceeding capabilities.Waveform11-GNX4_Audio_Input_Properties
  5. In Settings>MIDI Devices, enable anything Digitech USB-related. Waveform gives the devices an alias, which is shown in the screen shot below. We’ll need this alias later, so I point it out for your information.Waveform11-MIDI_Device_Settings
  6. Now we’ll switch to the GNX4 unit and complete the configuration there.
  7. Let’s set the MIDI channel for the GNX4. Press the Utility button to the right of the data wheel until the display shows “MIDICHNL”. Turn the data wheel until it shows “AL”. This sets the GNX4 to Omni mode where it can handle MIDI on any channel.GNX MIDI Config
  8. Now set the USB source option for USB channel 1-2. Before you begin, make a note of what the initial value is so that you can change it back when you’re finished. Press the Shift button under the built-in recorder on the GNX, then press the CF USB 1-2 SRC button. Use the data wheel and change the value to “DRUMS ST”. Press Shift to exit.GNX4_CF1_2_Drums_ST
  9. Return to your DAW now. Configure your MIDI track’s output setting on the far right-hand side of the track. I had to choose “Digitech Mac USB-2” as my default MIDI output. To test, press play on your DAW’s transport. If the GNX4 is receiving the MIDI, its level meter (at the top right-hand side of the built-in recorder) will show flashing lights. You will not hear any sounds in the DAW yet, but you will know that your signal is getting to the GNX4.Waveform11-Setting_MIDI_Source_In_Track
  10. Create a new audio track and name it “GNX4 Drums”. Set its input source as the USB 1 channel and its output to the standard 1+2 output. Turn on your live input monitoring and press play on the DAW. You should be hearing your GNX4 playing the MIDI file.
  11. Arm your “GNX4 Drums” track for recording and record your MIDI file. Your track should display a dynamic waveform of the recorded audio.Waveform11-Drum_Audio_Track_Settings
  12. If you want to try other GNX4 drum kits, feel free to change them and see what sounds the best to you. There are several stock kits available and auditioning them all may prove useful to you in your DAW’s mix.
  13. You may need to experiment with an ideal latency recording setting, and also setting it much higher for playback. In Mac, I needed to record at 16 ms and play back at 256 ms. In Windows 10, changing the latency for playback didn’t seem to be needed.
  14. At this point, the tutorial is complete.

Where To Go From Here

Now that we’ve seen that it’s possible to use your GNX4’s drummer capabilities in a DAW, I’d suggest a few enhancements. First, break the individual kit pieces into their own distinct audio output tracks. This will give you fine-grained control over each piece’s sound and allow for better mixing. Second, record multiple takes of the output audio with different GNX4 kits so that you can blend them together and see if a hybrid of the audio works in your style of music. Finally, experiment with integrating the GNX4 output with the output of other drum VSTs to create something new and unique.

Summary

I hope this tutorial has helped you and that you found it useful to learn how to play Digitech GNX4 MIDI Drums Through Your DAW.

Digitech GNX4 Dry Guitar Audio Signal Configuration Via USB

13 May 2020 – Written by Michael R. Myers

In this post, we’ll look at how to make use of the GNX4 dry guitar signal audio in home recording.

The Digitech GNX4’s configuration options allow for some very flexible audio output combinations. One of the most useful functions is to configure the USB 1-2 channels to send your complete output (amp, cabinet and effects on channel 1) and your GNX4 Dry Signal (DI) on USB 3-4 simultaneously to your computer’s recording software. With some minimal configuration in your DAW, you can record both channels’ outputs and store them for safe keeping and future modifications.

Why use a dry guitar signal?

This article lists a few of the best reasons why it’s worth your time now, and for the time you need it in the future. Remember, capturing the dry signal in the present may not seem like it matters, but if you need to re-amp or switch out a virtual amp in the future, having that saved DI will make completing your project much, much easier on you and/or the musicians whose work you are producing.

If you have a copy of Craig Anderton’s Power User’s Guide for the GNX4, this information is presented nicely on page 58 of Chapter 8 – Routing and Recording.  The purpose of this configuration is to set up the GNX4 to send the effects audio as mono on USB 1-2 and the dry guitar signal as mono on USB 3-4 simultaneously. 

Configure your GNX4’s Audio Output Now

  1. On the recorder section of the GNX4, press the Shift button
  2. Press the CF/USB 1-2 SRC button
    GNX4 USB1-2 SRC button
  3. Turn the Data Wheel until you encounter MONO ALL
    GNX4 CF/USB button
  4. Press the CF/USB 3-4 SRC button, which is to the right of the CF/USB 1-2 SRC button
  5. Turn the Data Wheel until you encounter DRYGUITAR
    GNX4 USB 3-4 button
  6. Press Shift to close the configuration mode

At this point, your GNX4 is configured to send mono effects on the first USB channel (1), and its mono dry guitar on the second USB channel(2) . In your DAW, you will have to figure out how to separate channel 1-2 and channel 3-4 as separate inputs so that you can capture each one to its own track. And remember to arm both tracks EVERY time you record so that your effects and DI tracks match!

A final note is that you will most likely need to adjust the levels of the USB channels at some point so that the audio is not too soft or so loud that it causes clipping.  The procedure is similar in that you would press Shift, and then the individual Channels’ buttons that are one row below the SRC buttons you just configured.

Digitech GNX4 Re-amping With Tracktion Waveform 11

In this post, we’ll look at how to configure Digitech GNX4 re-amping with Tracktion Waveform 11. The steps in this post are not limited to Waveform, and they should work in almost any other DAW if you’re willing to give it a try. Let me know if you have successfully re-amped using this post with a different DAW.

18 May 2020 – Written by Michael R. Myers

Skill Level : Advanced

The Digitech GNX4’s configuration capabilities permit users to re-amp a dry guitar signal (DI) from either the on-board 8-track recorder, or from USB configuration. This post focuses purely on the USB configuration so that a DI track in a DAW can be processed by the GNX4 and recorded as the GNX4 performs the track with the new audio output.

Before we begin, I would like to point out that using the MFX Supermodels that were available for the GNX4 would be preferred over the stock amps and cabinets. Unfortunately, they are no longer available for purchase at this time. If you can find a disc of the MFX Supermodels, your results will sound superior over the stock offerings in the GNX4. Check e-Bay for a disc of MFX Supermodels because people sometimes sell them there.

One final note…re-amping takes time and configuration effort on your part. It’s not as easy as pressing a button or switching effects. The steps need to be followed carefully so that you’ll have success with your new sound. You may want to wait until you are ready to do a batch of re-amps instead of performing them multiple times over your project’s recording sessions.

What You’ll Need to Re-Amp Your DI Tracks

  • Tracktion Waveform 11 – while free to use, it does require an account at their web site
  • Digitech GNX4 connected to a PC or Mac via USB
  • GNX4 drivers, if using Windows. Mac users do not any drivers
  • Ability to configure your DAW software for audio inputs and outputs
  • Ability to configure GNX4 to output an effected signal and a dry signal
  • Ability to configure GNX4 to input a dry signal to be re-amped
  • PATIENCE. The tutorial is lengthy and requires a lot of back-and-forth with configuration/settings.

Re-amping Overview

Re-amping a dry track gives you a lot of creative control over the sound of your guitar in a track. It allows flexibility to audition new amps and cabinets virtually for comparison to help you find “that sound” within your overall mix. Alternatively, you can make copies of your dry track and re-amp them to different amps and cabinets and then blend the results to create a sound that is unique and really stands out. The results are limitless and once you have some of your GNX4’s patches set up to your liking, you’re ready to go for future re-amping sessions. Remember to always capture dry guitar signals while recording so that Digitech GNX4 re-amping is always available for you. Now that you have a dry guitar track explanation, let’s use Digitech GNX4 re-amping with Tracktion Waveform 11.

Steps to Re-amp Using a GNX4

  1. Configure your GNX4’s audio outputs so that you have a dry guitar signal available.  See this post’s procedure for instructions.
  2. In your DAW software, set the Digitech GNX4 as the input audio source while it is powered on and connected with a USB cable to the computer.  In the image below, the GNX4 is set as my input audio source, and the UMC202HD is my computer’s audio interface where my studio monitors are connected.  The Sample Rate only offers 44.1 and the Audio Buffer Size should be configured.  The lower the buffer number, the less latency you’ll experience.  It may take a few tries for you to find the lowest, workable buffer setting to eliminate latency. Shows Waveform11 Audio Device options
  1. In Waveform 11, you will need to set up two audio tracks.  One will be assigned to the USB 1 (USB 1/2 with effects) input channel and the other the USB 2 (USB 3/4 dry) input channel.  For USB 1’s input, I called the track “ENGL 35” for the ENGL amp preset I have at position 35 on my GNX4 patches.  For USB 2’s input, I called the track “Dry DI” to hold the GNX4’s dry guitar output that was configured in Procedure 1.Waveform audio tracksZoomed Waveform 11 track view showing input sources
  2. To record both source tracks simultaneously, arm both tracks for recording and record your audio performance.  After recording, you should see waveforms on both tracks.  You’ll notice that the dry track’s waveforms will look much more dynamic than a track with effects. Recorded audio on tracks showing waveform data
  3. Audition the tracks to verify that the first track is your GNX4’s patch output and the second track is dry guitar output.  Assuming you have a dry guitar track recorded properly, you’re now ready to re-amp it within your DAW.
  4. Now that we’re ready to re-amp the dry signal into a different GNX4 patch’s output, this part of the process requires a temporary change in audio inputs and outputs in the DAW preferences, and a temporary configuration change on the GNX4.
  5. Follow Procedure 2 in this tutorial to set up the GNX4’s USB sources to re-amp audio.  After setting the input to REAMPUSB, make sure you are on the different GNX4 patch that you want to have receive the signal.  For example, I originally recorded my patch 35, but now I want to re-amp the dry recorded signal in my DAW on patch 74.
  6. In your DAW, you have to open your audio device’s preferences and configure the input and output sources again.  This time, you are going to select the USB 1-2 as both the input and the output audio source.  USB 1 will be on the left side of the pair, USB 2 will be on the right side of the pair.Waveform 11 configuration for re-amping
  7. Make a new audio track in the DAW.  Here I named mine “Rectifier 74” for my GNX patch that I have stored in position 74.  Set the new track’s input source as USB 1.  In Waveform, I have to pan this tracks’s audio 100% to the right.  If I leave it center-panned, I will also hear the dry guitar sound in addition to the new patch 74 sound.  Panning it hard right allows me to record only the sound of patch 74. Waveform 11 New track for re-amp
  8. Arm the new track and hit your record button.  The DAW’s transport will play the dry guitar sound and send it to the GNX4 to play on the selected patch, in this case patch 74.  When you see a waveform showing on the track, you’ll have indication that your GNX4 is re-amping the dry sound.  You WILL NOT hear any audio output from the DAW or your computer monitors while you are re-amping.  As you can see, the waveforms on ENGL 35 (red track) and Rectifier 74 (green track)are heavily compressed and look similar, but they are two different sounds.Waveform11 recording new re-amped track
  9. To audition the new track’s audio, you must manually change your DAW’s audio preferences to use an output of your audio interface or the computers speakers.Waveform 11 config audio output to hear re-amped track
  10. Switch back to track view in your DAW and solo the new re-amped track’s audio.  Press Play on the transport to hear the newly re-amped audio output.
  11. At this point, you’re finished with the re-amping of the dry track.  From here, you could try a few things like using the original track (ENGL 35) and blending it with the new track (Rectifier 74).  Or you could choose one track over the other based on how it sounds with other instruments like drums and bass being mixed in.  Or maybe you want to have several options/takes available so you could re-amp the dry track on several different patches to decide which one(s) work best within your mix.
  12. Remember to follow this procedure again to reset your GNX4 back to normal when you are finished your re-amping activities.
