Reamp DI Guitar Tracks From Your DAW with the ARTcessories Dual RDB Interface

In this post, I’ll show you how to reamp DI guitar tracks from your DAW with the ARTcessories Dual RDB interface. If you haven’t tried re-amping your DIs yet, you’ll find a great way to see how your DIs can sound running through varied analog gear. If you’re looking for a different guitar sound, or a way to augment your mix with different gear, re-amping is a great solution.

Before we continue, please realize that much of this content is generalized because each DAW, re-amp box and recording chain is different. What works for me with settings, levels and gear will be inherently different for you in your studio. In this post, I cover what re-amping is and generally how to accomplish it.

What’s Reamping????

If you’re new to reamping, the reamp box converts a balanced, line-level signal into an unbalanced, instrument-level (think dry guitar) signal. For home recording, you can record a dry guitar signal into your DAW of choice so that you have a clean, unaltered source for a guitar track. Using this dry track, you can play it through your DAW, have the audio signal leave your USB audio interface and flow into the reamp box. From the reamp box, the signal flows into an amplifier input, just as if you plugged a guitar directly into the amplifier. You amplifier is then hooked into a speaker cabinet which you mic and then record back into your DAW. With me so far?

A major benefit of reamping is you can do multiple auditions of a guitar track with different amps and cabinets, recording them into tracks in your DAW, allowing you to compare and choose the perfect sound for your mix.

Have a look here at the Wiki article covering the re-amp concept for a lengthier read.

What You’ll Need to Get Started

Overall Recording Strategy (Before Re-Amping)

Before we can get started with re-amping, we need to record some dry guitar tracks, also called DI tracks, into the computer’s DAW. Once recorded, the clean DIs can be re-used whenever we want to re-amp them into different amps, cabinets or other analog hardware.

To capture DIs, I use a passive DI box that is connected to my analog mixer via XLR. I pan the channel 100% Left so that on the mixer’s output, the DI is always on the left channel of the signal pair. I always record DIs with the processed signal (that one is panned 100% Right in the signal pair). In my DAW, I use two tracks – one is for the DI only and one is for the processed signal only. So for each track, I have the unaltered DI source and the output source.

So at this point, get to it and record your DI tracks in your DAW. Make sure your input levels are gain-staged correctly and they are not clipping or otherwise distorted. You need quality DI tracks to reamp DI guitar tracks from your DAW to produce quality re-amped tracks.

About Configuring the Re-Amp Signal Chain

After you have some decent guitar DI tracks recorded in your DAW, we can set up the signal chain that sends the DAW output through the USB audio interface to the re-amp box and out to the external amp/cabinet. Typically a microphone would be used to capture the amp and cabinet output back into the USB audio interface to the DAW.

A point to remember here is that the DAW’s output of the DI track will be sent to the USB audio interface for playback. In order to re-amp, the DI tracks need to be converted from the audio interface’s line-level back into instrument-level signals. The re-amp box takes those line-level signals and converts them back to instrument-level so that the signal can be fed into analog gear properly. Without using a re-amp box, the signal sounds horrible and is not able to be used to feed into amps properly.

Depending on your amplifier situation, you may use an actual amplifier or a virtual amp to reamp DI guitar tracks from your DAW. I typically send the re-amped signal to an iRig HD 2 that is connected to my iPad Air 2. My amp is a software solution running on the iPad and the audio is sent out of the iRig interface via an instrument cable that I connect to my analog mixer with another passive DI Box. Using this setup, I do not need a real amplifier, speaker cabinet or microphone to re-create the signal-it goes directly into my mixer and USB audio interface.

Steps to Reamp DI Guitar Tracks From Your DAW

  1. Record your clean guitar DI track(s) in your DAW. Make sure they are gain-staged so that they are not too low or clipping.
  2. Unplug your left side output cable on the USB audio interface and insert the TRS to TRS (balanced) cable.
  3. Connect the TRS cable to your re-amp box’s input. If you have a gain knob on the re-amp box, you may need to adjust its application to ensure the signal entering the re-amp box is not too low or clipping.
  4. Insert a mono guitar cable (TS to TS) into the output of the re-amp box and into the amplifier’s guitar input jack. If you want to use an overdrive, tube screamer or distortion pedal, run the re-amp box output to the pedals first, then connect the pedal output to the amp guitar input.
  5. In your DAW, press play to audition the DI track. If you’ve done things correctly, you will now hear the DI audio coming through your amplifier.
  6. You may need to tweak levels at this point in the playback of the DI, the gain knob on the re-amp box, and so forth. I’ve found this part of the process can take the longest to get matched up.
  7. When you’re content with the re-amped audio, record it to a new track in your DAW with a microphone or another audio interface.
  8. When finished re-amping, disconnect the TRS cable from the back of the audio interface and re-connect your normal output cable.


If things went well, you were able to feed a DI guitar track from your DAW into a re-amp box and use a different amplifier/speaker cabinet to get a new sound out of the DI. Or, if you have several amps available, you can see which one works best in the mix by recording them all and comparing or combining them. If you’re like me, you also have amp sims on IOS devices that can be leveraged on the cheap to get you close to name-brand gear for pennies on the dollar.

Build a DIY Reamp Box

In this post, I’ll show you how to build a DIY reamp box from a tutorial I found on YouTube recently. If you’re reading this, you probably know what a reamp box is and why you would need one in your recording studio. You probably also know that the commercially available reamp boxes can easily cost $100 USD. Using some of your own skills and the provided materials list, you can make your own reamp box for around $25 USD. For me, it was not an option to spend so much money on a commercial product, so this post covers what I did to build a reamp box.

If you’re new to reamping, the reamp box converts a balanced, line-level signal into an unbalanced, instrument-level (think dry guitar) signal.

What You’ll Need to Get Started

  • Watch this video on YouTube entitled “How to build a REAMP box and WHY you need one” by Life Harmonic. In the video description, he lists all of the components you will need to order to build the reamp box. The complete list is shown here in Step 1. Be sure to check the video’s comments if you have any questions because several common ones are answered there.
  • An electric drill and drill bits capable of making up to one inch holes. I purchased 2 step drill bit products from Harbor Freight for my cuts. This one is for the larger hole, this one is for the smaller holes.
  • A soldering iron and solder
  • Wire
  • Mounting hardware – screws, glue
  • A workbench vice to hold your aluminum box for drilling
  • Phillips head screwdriver
  • 3/8″ wrench
  • 8 mm wrench
  • Wire cutters
  • Wire clippers

Step 1 – Order your components

Here is the list of components you will need to order if you do not already have them on-hand to build a DIY reamp box. Since I didn’t have any supplies, I had to buy everything I needed for this build. I used the suggested list in the YouTube video where possible. I ordered the components in the beginning of December 2020, so the cost may be different for you when you order. I also had to use two different electronics supply companies due to inventory unavailability for some items at Newark. I am in the continental USA and had to pay $9.99 to each company for shipping, and each was received in 3 business days.

Supply List for Reamp Box Build

Step 2 – Measure your placement for pilot drill holes

You’ll need to mark four (4) initial spots for drilling. After those holes are drilled, you’ll drill two (2) more for the XLR jack mounts.

Starting from the top of the pedal’s face, there needs to be one hole for the XLR jack at 25mm down from the top, from the left side. Under that hole will be two (2) holes for the potentiometer at 44.5mm from bottom and 10mm from left, 6 mm from right for the toggle switch. On the bottom of the pedal, we’ll drill the hole for the 1/4″ output jack centered at 13.5 mm from top. 17.5mm from left side.

Step 3 – Drill the holes in the box

I used a 1/16″ drill bit to make all pilot holes. Secure the box in a vice so that you are being safe while drilling the metal.

Drill the holes you marked in the previous step with the small drill bit. Now that there are starter holes, you can use larger bits or the step bits to make the holes to the proper size.

After drilling the four (4) main holes, you will need to drill two (2) pilot holes for the XLR jack. Carefully insert it into the metal box and use your pilot drill bit to find the spots for the XLR connectors and drill them from the inside out.

The XLR hole will need to be 7/8″ or 22 mm. The potentiometer hole is 5/16″ or 8 mm. The toggle switch is 1/4″ or 6 mm. The 1/4″ bottom jack (not pictured) needs to be 1/2″ or 12 mm. Finally, the two (2) XLR jack connector holes need to be 1/8″ or 3 mm.

Step 4 – Install the components

To build a DIY reamp box, start with the XLR jack. Mount it with two #4 screws.

Install the toggle switch and use a wrench to firmly tighten the nut.

Continue with the installation of the potentiometer and the 1/4″ plug and tighten with a wrench to secure them into the unit. You need to clip off the metal tab on your potentiometer if it has one, otherwise it will not mount flush against the box’s interior.

At this point, here’s what your reamp box should resemble.

If you ordered the same knobs as I have listed, you will have to drill them out a TINY amount so that they fit the potentiometer’s shaft. I used a 15/64″ bit and carefully made the button’s shaft hole a tiny bit wider. If you go too far, you can always place a small amount of duct tape on the potentiometer’s shaft to snug the button.

Here is my final build.

Step 5 – Solder the components to build a DIY reamp box

To simplify this post, I did screenshots of the original video since the original presenter filmed it cleanly and clearly.

  1. Solder two wires to the middle and right side of the potentiometer
  2. Glue the transformer to the potentiometer
  3. Connect middle potentiometer wire to Pin 1 of the TS Jack (right hand side pin at top of jack)
  4. Connect resistor to bottom of transformer and wind around the transformer pins. Clip excess resistor wire.
  5. Solder lower left side pin of TS jack to left side of resistor/transformer
  6. Solder right side pot wire to right side of resistor/transformer
  7. Solder Pin 1 of XLR to center of toggle switch
  8. Connect bottom toggle switch to the left hand side TS Jack pin (along with connection you already made in Step 3)
  9. Connect XLR Pin 2 to right of transformer
  10. Connect XLR Pin 3 to left side of transformer
  11. Solder XLR Pins 2 and 3
  12. Here is the final product after all connections have been made.

Step 6 – Test it

Plug L main out of USB audio interface into TRS to XLR cable. May be able to use the headphone jack output as well.

Plug XLR into reamp box

Plug TS into amp

Press play in DAW with dry guitar signal

Adjust level knob as needed. Flip toggle switch to eliminate any ground loops.

Did it work without any noise/interference?


If yo u’ve made it this far, and you’ve followed all of the steps, you should have yourself a very nice reamp box to use in your studio. In a few hours’ time, you’ve learned how to build a DIY reamp box and are ready to make your recordings shine with limitless amping possibilities.

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.


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!

Create a TX16Wx Sampler Drum Kit in Tracktion Waveform

In this post, we’ll learn how to use a free sampler plug-in from CWITECH to create a custom drum kit with audio samples. Creating your own drum kit to play MIDI parts allows you to have creative control over your kit’s component sounds and can allow you to develop a reusable signature sound for your productions. Let’s get started to create a TX16Wx sampler drum kit in Tracktion Waveform 11 Free.

What is a Sampler?

At a high level, software audio samplers allow you to define your own virtual instruments. You can assign specific audio sample files to a MIDI keyboard mapping so that the keyboard plays that audio sound when the keyboard key is pressed. Your mappings can be simple, with one audio sample assigned to one key. Or, for the advanced user, multiple samples can be assigned to one key at various velocities or to just blend multiple audio samples together. Samplers are a great tool to create new, unexpected and unique sounds.

Virtual Drum Kits and Samplers

If you have ever used a virtual drum kit, like MT Power Drumkit, you’ll quickly recognize sampling in action. When using the plug-in, your MIDI notes are automatically rendered as drum kit pieces’ audio. Standard MIDI mappings help to ensure that drum kit components are used as expected so your output audio is rendered as expected. Using a virtual drum kit is easy for many people because the mappings are already present and you can just drop it into your project and render your drum parts.

In contrast to drum plug-ins, samplers are very manual by nature and require time to set up and mapping audio samples to keys. Fortunately, most allow you to save your layouts for easy re-use in the future. Be aware that creating your own sampled drum kit can be very satisfying, but there is time spent on building, testing and tweaking until it’s ready for instant re-use. Your rendered audio will be as good as the quality of the audio samples you use.

Multi-velocity Hits Make Sampled Drums Sound Better

Now that we’ve briefly covered what a sampler is used for, and contrasted how it’s similar to a pre-made virtual drum kit plug-in, let’s talk about audio samples. The quality of your audio sample files is extremely important. If you are looking to really make your sampler sound like a convincing acoustic drum kit, you’ll need high-quality samples and samples made available for multi-velocity hits.

MIDI allows for the specification of note hit strength from zero (0) to one-hundred and twenty-seven (127). If you set all of your samples to trigger at the same velocity, say 127, it will be the loudest representation of the sample and it will sound like a machine is playing the part. There will not be any natural variation in the hit strengths and it will sound very tedious to the listener.

By setting variable MIDI velocities, we can tell the sampler to play specific files at a velocity value, or for a range of velocity values. For example, say we have four (4) multi-hit samples for a snare drum. We can tell the sampler for velocity twenty (20) to forty (40) to play “snare_hit_light.wav”. Then for ranges forty-one (41) to sixty-four (64), we tell it to play “snare_hit_medium.wav”. Hopefully. You can see that we are now alternating between two (2) different samples based on the MIDI notes’ hit strength. After we map our remaining four (4) samples, our snare will sound much more varied than using one (1) sample for all velocities.

Some audio sample producers provide a free set of samples, usually with one hit per instrument. In my experience, quality kits that require payment contain multi-hit files, some with eight (8) or more velocities per instrument. Be certain to investigate your drum audio samples before spending money to make sure that there are multi-velocity hit samples and that the files are in a non-lossy format, like WAV or AIFF.

What You’ll Need to Get Started


I have limited experience with sampler software. This tutorial is the result of me searching, struggling, cursing and finally coming up with a free, working, repeatable solution. If there is anyone who can recommend easier, better or faster, I am proverbially all ears. I welcome any constructive feedback that can help us all get there better and faster.

Finally, the steps in this tutorial will produce a full drum kit, however it will be a stereo (Left and Right) output of all sounds combined. While this will probably work for a majority of people, if you want to split the outputs onto separate channels, you’ll need to do research how to do that on your own. It also does not use multiple velocity groups or any sort of round-robin to randomly select samples from groups.

Steps to Create a TX16Wx Sampler Drum Kit

  1. Install the CWITECH TX16Wx sampler on your computer with its installer.
  2. Create a new Waveform 11 project.
  3. Create a new track and name it “TW16wX_Drum_Sampler”.
  4. Add a drum kit MIDI pattern or file onto the track. It should have multiple kit instruments within the pattern.
  5. Add an instance of the TX16Wx plug-in to the track. Your project should look similar to this image.Waveform11-TX16Wx_Track
  6. Open the sampler plug-in you added to the track. We need to set a few properties and save it. First, change the Midi value to “Omni”. Second, name your program. I called mine “Myersclan_Kit”. Finally, click the Save Program As button and choose a location on your computer. I recommend storing it in your Waveform project folder so it stays with the other project files.Waveform11-TX16Wx_Initial_Config
  7. Let’s create our kick drum trigger in the sampler. Click the Regions button located below the Save Program As button you previously clicked.
  8. The regions view will show a piano keyboard and a screen with grid lines.Waveform11-TX16Wx_Empty_Regions
  9. Click the New Region button. By default, the region fills the entire grid with a green colored fill. Resize the green area to fit on the C2 keyboard key only. You can verify the C2 area by looking at the LO K and Hi K values under the grid.TX16Wx_Create_New_Region
  10. To the right of the Create New Region button, click the button that looks like it has six (6) small squares on it. This enables velocity layers when we drop our audio samples in an upcoming step.
  11. In a separate file explorer (Windows) or Finder (Mac) window, open the folder that contains your kick drum samples. We are going to drag and drop them onto the Regions screen on the C2 key.
  12. Select your kick drum sample(s) and drag them to the Regions window and drop them on the C2 key. You may need to resize and re-order them. For my Manic Metal samples, I have four (4) kick drum samples, named KickV1, KickV2, KickV3 and KickV4.
  13. Under the piano keys, the grid contains rows for each sample and its mapping. Edit/Configure yours similar to mine, but factor in differences like the total number of samples you are using. Since I used four (4) samples, I divided the one-hundred twenty-eight (128) possible velocities by four(4) to get thirty-two (32) hit values per group. Use the Lo V and Hi V values to specify the range starts and ends.TX16Wx_Kick_Samples_Dropped
  14. Test your configuration by using your mouse to click on the C2 piano keyboard key. You should hear your kick drum sound play back. If so, you’re ready to move on.
  15. Optionally, depending on the samples, you may need to adjust the tails of the audio samples so they play fully. Click the Sounds button near the top of your kit. At the bottom of the screen, a blue section will appear. To adjust the tails, click the round markers and drag them to the right-hand side. The longer the blue bar, the longer the sample plays.TX16Wx_Kick_Samples_Tails
  16. Return to the top of the screen and click the Save button to store your changes.
  17. In Waveform, play your track. You should hear only kick drums at this point.
  18. Now for the work involved with sampling – repeat this Key assignment process for each of your kit’s pieces by adding samples for them to their key assignments. Refer to the general MIDI recommendations for drum key assignments to keep your kit standard. Here’s the final kit image of my complete drum kit.TX16Wx_Full_Custom_Kit

Where To Go From Here

With some additional effort, you can modify the configuration of your sampler instrument’s pieces to output audio to dedicated channels instead of the standard combined 1/2 output that was presented here. Some folks want to have fine-grained control of the audio outputs they configure for their projects, and that is a definite possibility with some TX16Wx configuration. Just be aware that the sampler does have a limit on output channel pairs in the free version.


Setting up a software sampler is a great way to make a drum kit that defines your personal style. You can combine one or more samples to really create new and unusual sounding kits, or you can aim to make a really convincing kit that may sound divine on your final track. Either way, you have the power and choices to drive how your TX16Wx Sampler drum kit will sound.

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.


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.
