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.

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.


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.

Extract MIDI Audio and Notes in Waveform 11

Have you ever wanted to output a MIDI file as audio and also capture the actual MIDI notes that produced the audio? A practical usage for this process is extracting the MIDI from a file where there are multiple instruments in the file, such as a drum kit’s kick, snare, toms and cymbals. With the extracted MIDI, you have the source data available to help you create new instrument parts, variations or other embellishments without the need to endlessly copy, paste and manually delete instrument parts you don’t need. Follow the steps in this post to learn how to extract MIDI audio and notes in Waveform 11.

Why Do You Want to Extract the MIDI Notes????!!!!

That is the question I have received numerous times on various Internet forums and other groups while I was trying to figure out how to extract MIDI notes. I’d also get suggestions like “Just record the audio output and be happy with that” or “Nobody needs to capture the MIDI notes while they’re playing” or “Just copy the whole MIDI file to a new track, highlight what you don’t want, and delete it”. I even checked in with Tracktion’s technical support team, got a case number and in the end they said it couldn’t be done easily. I assume the technical support agent was also confused as to why I wanted the playing audio output AND those corresponding source MIDI notes. Fortunately for me, I got more motivated to find the solution, and I did it with some free VSTs and a video tutorial on YouTube by Bill Edstrom.

First, Let Me Explain…

To step back a moment, here’s my motivation to extract MIDI audio and notes in Waveform 11. I made a Waveform project that uses a source MIDI file for performance by a VST drum kit instrument. The VST drum instrument, MT Power Drum Kit 2.0, plays the MIDI file and sends each individual instrument’s audio to its own track so that I can record the drum kit pieces’ audio on distinctly separated tracks (kick drum has its own track, the snare has its own track, etc.). I assume you do something similar to control the output levels of each of your kit’s pieces. If you aren’t separating out your kit components into dedicated tracks in your DAW, you may want to look into that practice sooner than later, especially if someone else mixes your work.

After I have created each instrument’s audio track in the DAW, I then export the audio to files and then import into another DAW for mixing and EQ adjustments. With me so far? Good. Let’s continue.

After a few sessions of recording audio tracks from the MIDI file, I realized that I may want to output the source MIDI notes in addition to the output of the audio. For example, having the kick drum’s audio and source MIDI notes allows me to save small, defined pieces of performances that can easily be copied, re-used or altered easily. If I decide that I am not liking a certain VST’s audio output, I can easily swap the VST drum instrument and re-record from my source MIDI. If I didn’t have the MIDI notes, I would potentially have to chop the audio file and edit it to create variations which could take a lot of time and effort.

But right now, I know you are still asking yourself why I would want to do this. Couldn’t I “just copy the MIDI from the main source track, delete out the instruments I don’t want and continue along my way”? Sure, but that could potentially be a lot of work and re-work if I make one or more errors in my edits/copy-paste.

For my workflow and the way I work, I tend to write my drum parts and guitar riffs in very small sections, generally 1 or 2 bars at a time. When I write in small sections, I can audition the audio and the MIDI to tracks to do A/B comparisons easily. I can edit the captured MIDI and play it back in small sections to create variations and copy them back up to my main source MIDI track as I build the overall song. The best part is that I am using technology to do the repetitive grunt work of capturing audio and MIDI notes with simply arming tracks for record and doing a take.

What You Need To Succeed

Make sure you install all of the prerequisite plug-ins before attempting to continue.

Due to the length of this tutorial, I plan to write continued variations for specific uses of the techniques presented. These include using multiple VSTs to generate different instruments’ outputs for blending, auditioning various drum kits during playback and much more.

This lesson is the just the starting point of the series and shows how to use one drum kit plug-in to capture individual drum kit pieces’ MIDI source notes and the corresponding output audio on separate tracks.

Steps to Extract MIDI Audio and Notes in Waveform 11

  1. Create a new Waveform 11 project. Delete all tracks so we can start fresh.
  2. Create a new track and name it “MIDI Source”. This track will hold our drum pattern file(s) and represent our entire drums for a track.Waveform 11 Add New MIDI Track
  3. Add an empty Rack plug-in to the MIDI Source track. Within the rack, drag the red line (MIDI) from the left-hand side dot straight through to the right-hand side dot. This will simply pass the MIDI data out of the track. Name the Rack “MIDI Through”.Waveform 11 wire MIDI in rack
  4. Place a MIDI file on a track. For this tutorial, use any drum MIDI you want, just be sure it has multiple instrument parts like kick, snare, cymbals and toms so that we can separate them into their own source tracks.
  5. Right-click in the area under MIDI Source and select “Create a new folder track”. We will need to make a group of tracks per instrument. Groups allow for organization and easy enable/disable operations during playback or for recording. Name the folder track “Kick (36) Group”.Waveform 11 - Kick Group Track
  6. Let’s make our first sub-track for the kick drum. Create another new track under the group track. Grab the new track, hold your mouse button and drag it under the folder track until the folder track looks like it lights up a bit. Drop the new track. If you performed this movement successfully, the new track shows a bit indented under the folder track, and the folder track has a small indicator icon on its left-hand side. Clicking the indicator either expands or compresses the view to show/hide the new track. Name the new track “Kick MIDI Filter”.Waveform 11 - Create sub-folder track
  7. Kick MIDI Filter is the track that is going to help us receive the MIDI Source track’s notes and will filter the notes to a specific MIDI key value. Recall that (36) in the group folder track’s name? That 36 is the key value of the General MIDI specification for a bass/kick drum. I like to place the values in the names so that I know where they are mapped visually.
  8. Open the MIDI Through rack on the MIDI Source track. At the lower right-hand side of the dialog window for the rack, click on the box and drag it to the plug-in area of the Kick MIDI Filter track so that it has an instance of the Rack. This instance allows us to receive the MIDI Source track’s MIDI output.Waveform 11 - Drag Rack Instance to Track
  9. Now that we are receiving the MIDI input on the Kick MIDI Filter track, we need to filter for the actual kick drum note value. Add an instance of eaReckon’s MID Polysher plug-in directly after the rack instance you just added. After adding, you will see the Polysher configuration window. Set the two key range values to 36, which is the kick drum’s MIDI note value. Note how all of the piano keys will turn red except for 36. Close Polysher after the configuration is completed.MIDI Polysher Kick Drum Filter
  10. Now that we have a track that is filtering the MIDI source data to only handle the kick drum, let’s make a new sub-track to “print” the kick drum’s source notes. To save the notes, we simply arm the new track for recording and it saves the notes to the track. Follow the previous steps for making a new track and dragging it under the “Kick (36) Group”. It should be under the “Kick MIDI Filter” track. Name the new track “Kick Only MIDI”.Waveform 11 - Create sub track
  11. On the new track, we’re going to add our drum VST instrument so that the MIDI the track receives can be printed. It will also produce the audio output of the filtered kick drum so that we can make a new audio track to capture (“print”) the audio output. Add MT Power Drumkit as a plug-in to the “Kick Only MIDI” track. Be sure to open the drum kit and click the “Skip” button so that the plug-in makes audio output.
  12. Now we’ll add the final sub-track to the group. Create another new track and drag it under “Kick Only MIDI” in the folder group. Name the track “Kick Only Audio”.Waveform 11 - Create sub track
  13. We’re finished creating all of the sub-tracks within the kick drum group. Let’s wire the tracks up so that we get MIDI notes and output audio.
  14. Right-click the empty area under “Kick Only MIDI” and choose MIDI Tracks>Kick MIDI Filter. This sets the source of the track to our MIDI notes from the Rack on the “Kick MIDI Filter” track.Waveform 11 - Configure MIDI Notes' source
  15. Right-click the empty area under “Kick Only Audio” and choose Audio Tracks>Kick Only MIDI. This sets the source of the track to our Power Drumkit audio performance from the “Kick Only MIDI” track.Waveform 11 - Configure audio output  source
  16. We’re finished with all of the kick drum configuration at this point. Now it’s time to test and prove we will get only kick drum MIDI notes on “Kick Only MIDI”, and only the kick drum’s audio output on track “Kick Only Audio”.
  17. Arm the bottom two tracks in the kick drum group for recording and press the R key to record.
  18. Press the spacebar when your play head passes the end of your MIDI file to stop playback. Press the W key to return to the start of your bars. You should now see that “Kick Only MIDI” has only kick drum notes, and that “Kick Only Audio” has the recorded kick drum audio.Waveform 11- Waveform-Captured MIDI and Audio
  19. At this point, you can repeat the steps and make a group for each of the instruments in your drum kit. Be sure to change the MIDI note value in the Polysher plug-in within each group so that you are filtering for the correct instrument.


We’ve finally reached the end of this tutorial. You now know how to extract MIDI notes and audio in Waveform 11 Free. While it was a long journey, you can save your project so that the configuration is finished and ready for your next project.

Rename A Tracktion Waveform Project

Have you ever tried to rename your saved Tracktion or Waveform project‘s name? It’s a multi-step process and not overly obvious how to complete. Follow the steps in this post to learn how to rename a Tracktion Waveform project.

19 May 2020 – Written by Michael R. Myers

Skill Level: Beginner

Contents of a Waveform Project

Before I outline the steps to rename a project, let’s take a quick look at the components of a Waveform project. Knowing these parts should help you to understand what we will change with the rename operation.

When you create a project, Waveform (or Tracktion) makes a folder with the name you specify. Within this folder, it makes several sub-folders and it creates the project file and the project’s edit file.

Steps to Rename the Project

  1. Open your project in Waveform that you want to rename.  I called my project “DumbProjectName” when I created it, but now I want to give it a more meaningful name.
  2. Click the project name in the Projects tab. Waveform Projects screen
  3.   In the properties window at the bottom of the screen, change the name of the project and press Enter.  I have just re-named it to “Song01_Source”.  Notice that the project name in the Active Projects pane automatically shows the new project name, but the Edits file name still shows with the old project name.Waveform Rename project - Step_3
  4. Click on the Edit file name in the Edits pane.  Similarly to changing the project name, provide the desired name in the Edit pane.  Your project name and edits file name will now match. Close Waveform and continue to the next step.Waveform Rename Project - Step_4
  5. Finally, let’s change the folder name that contains the project so that it has the new project’s name.  Open your file explorer and navigate the the folder that contains your project’s folder.  Rename it to be the new project’s name.  The folder, *.tracktionedit file and the *.tracktion file should all show as having the same name.Waveform Rename Project - _Step_6
  6. Congratulations! Your project folder, its project file and edits file are now renamed.


Now you can rename a Tracktion Waveform project. It probably was not overly obvious how to complete it successfully, but moving forward you can reference this post if needed. What this situation taught me personally was to make sure I name a project properly as one of the first steps I complete when creating something new.

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.


I hope this tutorial has helped you and that you found it useful to learn how to use Digitech GNX4 re-amping with Tracktion Waveform 11.  If you have any constructive feedback, please contact me at the e-mail address listed in the heading of this tutorial.  Thanks for reading and I wish you great luck recording with the GNX4!
