Some of my favorite guitar sounds involve using Ampire’s amp, bypassing its cab, and adding a cab from the Helix Native plugin. Others involve creating custom cabs using the Pro EQ, or putting two cabs in parallel and throwing one out of phase. But loading an additional amp sim or EQ, or setting up parallel routings, and then dialing in the right settings is a hassle. It also wastes CPU power. So, I was glad to find an alternative. Thanks to the mysterious IR Maker utility plugin, it’s easy to create IRs for Ampire’s User Cab from other amp sim cabs, equalization, and stacked parallel cabs.

Make sure you download the free IR—the download link and description are at the bottom.

Meet IR Maker

Here’s the overview:

• Choose a mono amp sim cab or cab substitute (e.g., EQ).
• IR Maker’s output sends a frequency-sweep signal to the new cab’s input.
• The new cab’s output feeds the IR Maker’s input.
• IR Maker analyzes the frequency response characteristics of the processed sweep signal, crunches some numbers, automatically places the impulse in an impulse folder, and voilà—a Cab IR you can load in Ampire’s User Cab.

Song Setup

For this to work, a patch cable needs to connect an audio interface output to an audio interface input. It’s helpful to create a Song Setup specifically for grabbing impulses:

1. Export your current Song Setup so you can return to it after grabbing your impulses.

2. Create a new Song Setup. Dedicate a mono input and mono output to IR Maker (fig. 1).

3. Add an audio input for your guitar, and a Main stereo output, so you can test the impulses in Ampire.

4. Export this new Song Setup preset for future use.

5. Patch a physical patch cord between the audio interface input and output selected for the IR Maker (in this case, it’s input 3 and output 3).

Figure 1: The IR Maker mono input comes from Mic/Line input 3. The IR Maker mono output goes to Line Out 3. An additional audio input allows testing the IRs by playing guitar through Ampire.

Mixer Channels Setup

1. Insert the amp sim or EQ-based cabinet you want to convert to an IR (fig. 2). Insert the IR Maker plugin after the cab. (The additional Pro EQ³ after the IR Maker is optional. We’ll cover that later.)

Figure 2: Channel setup and IR Maker UI. The setup is about to generate an IR from an edited Helix Native cab.

2. Assign the IR Maker channel input to IR Maker In, as created previously in Song Setup. Assign the IR Maker channel output to IR Maker Out, also created previously in Song Setup.

3. Record-enable the IR Maker trackand enable the input Monitor.

4. Open the IR Maker UI and test the setup. Click on Detect. If Latency shows 0, there’s a problem with either the physical patch cord, the input/output assignments, and/or the track not being record- and input monitor-enabled. Fix the issue, then proceed when Latency is a non-zero number.

5. Check the Normalize and Show boxes.

6. Options trades off calculation time and fidelity. For cabs, I use a 60 second sweep and 0.34 second IR time. This takes longer to create an IR compared to using a shorter sweep, but captures the best quality.

7. Destination shows where the impulses will be saved. Note: Because Show is selected, as soon as IR Maker creates the impulse, its associated folder opens. Then, you can just drag the impulse into Ampire’s user cab so you can hear what it sounds like.

Ready to Rock!

1. Test the levels. Click on Start IR Recording and check the sim’s or EQ’s input and output levels, as well as the IR Maker channel input. Avoid distortion. Any files are saved, so choose “Test” as an initial IR name. Then you can delete the “test” files easily after you’re finished testing levels. It may take a few tries to get the levels right.

2. Once the levels are set, give the IR a useful name (e.g., the cab’s name). Click on Start IR Recording. Wait for the calculations to complete, and your IR capture is done.

3. Drag the IR into Ampire’s User Cab graphic, and play guitar through the guitar track to hear the results.

About the Free IR Download

The free IR custom cab uses 12 stages of Pro EQ³. The IR is designed to give the VC 30 amp a more open sound, and works very well with power chords. Select the User Cab in Ampire, and drag the IR on top of the User Cab’s graphic.

Doing custom cabs with EQ usually needs more than one EQ’s worth of stages, so being able to preserve that as an IR is convenient. The IR is trimmed to 2048 so that it’s compatible with Helix Native as well as Ampire. I prefer the IR to the Helix Essex A30 amp’s default cab (2 x 12 Silver Bell).

Comments

• The optional Pro EQ³ after the sweep shaves off the very highest frequencies (above 15 kHz, with a 24 dB/octave slope). This reduces high frequencies that could cause aliasing.
• The IR will be longer than needed. Ampire is tolerant of long IRs, but you can reduce the duration considerably. 50 ms is usually enough.
• This process may seem complicated, but it’s foolproof once the setup is correct. Just follow the steps above—and enjoy your alternate cabs!

The self-taught multi-instrumentalist and St. Louis native talks about taking his leap.

A life in music requires passion, creativity, and dedication – and for many creators, their trajectory can be traced back to a defining moment that changed everything: the moment they took the leap.

St. Louis native Mad Keys is a multi-instrumentalist and alt hip-hop producer whose soul-heavy sound has led to two full-lengths, four EPs, and a substantial selection of singles drenched in lush melodics and groove-heavy rhythms. As a self-taught musician, the key takeaways from Mad Keys’ musical journey have been “the importance of perseverance, the value of taking risks, and the power of community.”

Watch as Mad Keys performs his unreleased track “Powered” through the all-new PreSonus Quantum ES 4 audio interface, and talks about his creative process, teaching himself to play piano, and how cooking up a song is a lot like brewing a great cup of coffee.

When it comes to writing music, Brandon McCadney – aka Mad Keys – aims to strike a balance between time-honored processes and a fundamental openness to whatever excites him at the moment. “I’m definitely a process-driven person, and that shows up in a lot of areas in my life. But my process changes a bit each time I sit down to create. It truly depends on what I’m inspired by at the moment.”

It’s a balanced, contemplative approach that Mad Keys is quick to compare with another of his favorite daily processes. “For me, making a great cup of coffee is kind of like sitting down to create a song. In both cases, I have a routine that requires me to have patience and focus.”

Keys was raised in a musical family and learned to play violin when he was just 9 years old – a move that would introduce him to classical elements of discipline and melodic instrumentation at a very early age. But it wasn’t until high school that he discovered hip-hop and jazz. “I was listening to what everyone else was listening to: Gucci Mane, Jeezy, and Lil Wayne. I’m thankful for my brother and sister because they introduced me to artists like OutKast, N.E.R.D., Kanye, Lupe, and Santigold.”

One day, he heard a friend playing Coldplay’s “Trouble” on piano, and was immediately captured by the sound. When he asked his friend how he figured it out, “he told me that he learned how to play that song from a video on YouTube. So, I went home, turned on this old keyboard, opened up the tutorial, and learned that song. It was at that moment when I said ‘Yo, I can learn how to play piano!’”

Being an independent artist certainly has its share of ups and downs, and none more so than during the global pandemic. “There was a pivotal moment in 2020 when I almost gave up on music. My wife and I had just moved to a new city in the middle of the pandemic, and I felt lost. I remember telling bae that I might put music on the back burner. But that same night, I received several signs urging me to persevere. I decided to start creating visuals of myself making music in my room, not knowing where it would lead. I had no idea that the next 4 years would lead to building a growing community of supporters, producers, and creatives.”

Four years and several soulful albums later, Mad Keys continues to grow and develop as a musician. But his aspirations go far beyond mere technical improvement, serving a deeper purpose as a vehicle for personal growth and a daily reminder of the power in community: “My sonic leap wasn’t just about honing my talent: it was about learning to bet on myself and embrace the unknown.”

Sure, you can follow your virtual instrument with an audio compressor. But there’s a problem: an instrument’s dynamics and expressiveness depend on the notes’ velocities—not just the audio output. Velocity triggers different samples, alters filter settings, affects envelopes, and much more. An audio compressor can’t compress velocity. So, audio compression can help tame audio levels, but it can’t enhance an instrument’s expressiveness.

Fortunately, there’s an easy way to apply dynamics processing to MIDI velocity. The principle is the same as audio compression: Set a threshold, choose a ratio, and finally, add makeup “gain.”

Fig. 1 shows MIDI velocities from 1 to 127. Of course, this wouldn’t be a real part, but it’s the easiest way to show how MIDI compression affects velocities. Let’s set a threshold at MIDI velocity 80, and compress above that with a 2:1 ratio. Note where velocity 80 is in fig. 1.

Figure 1: MIDI velocities from 1 to 127. We want to set the velocity compressor’s threshold to 80.

Select all the velocities above the threshold for processing (fig. 2).

Figure 2: Velocities above the “threshold” are selected.

To compress the selected velocities by 2:1, choose Action > Velocity and multiply by 0.5. This is the same as a 2:1 ratio in an audio compressor (fig. 3).

Figure 3: Velocities above the threshold are compressed by 2:1. Note how the slope is less steep.

Next, drag the selected velocity values up so that the compressed velocities line up with the velocities below the threshold. Because the velocities are still selected, you can just click on the left-most selected value, and then drag it up to its original velocity value of 80 (fig. 4). Now there’s a smooth transition at the threshold.

Figure 4: The compressed velocities pick up where the unprocessed velocities leave off.

Adding  “makeup gain” is easy. The simplest option is to select all the velocities, and drag upward. Or, select all the velocities and choose Action > Add to add a constant. For example, after compression, the highest velocity is 103. So, adding 24 will raise all the velocities, with the highest one at 127 (fig. 5).

Figure 5: Like an audio compressor, the lower levels have been brought up, and the peaks have been reduced.

This is just one of the ways you can process MIDI velocity dynamics. You can also do expansion, limiting, and gating. If you’re interested in these types of processing as well, drop a note in the comments below.

Of course, you may want to compress the audio output as well. But in many cases, applying dynamics processing to an instrument’s MIDI data will give more expressive results than you can obtain with audio compression alone.

Watch the independent artist and Wiz Khalifa producer cook up a song in a single day

Imagine meeting someone for the first time and making a song together. That’s what independent artist KOTA the Friend and Wiz Khalifa producer RMB Justize did, producing a complete track at PreSonus HQ in just one day – with Studio One as their “one-stop shop [for] production, vocal recording, [and] mastering,” and TuneCore to “release the music, put a cool picture on it, put our name on it, and let the world hear it.”

Watch the making of their track “She’s Gone” below, and read on for more behind the scenes content.

Everyone loves a good collaboration – but working with others can be a challenge, especially when you’re a fiercely independent artist like Kota the Friend: “I record myself, make my own beats a lot of the times, I even mix myself sometimes.” It’s a boldly autonomous philosophy that informs his artistic approach and extends to the process of getting his music out into the world: “I’ve been able to sustain success as an independent artist just by constantly putting out music, putting out content, feeding the fans, and really going out on the road, going out on tour. We go to Europe every year. You know, people listen to the music and they’re vibin’ with it all year – in their houses, in their cribs, in their cars, on their way to work. And so we try to be there for them.”

“I even mix myself sometimes,” he says, but even a fiercely independent philosophy has its limits: “then I send it off to somebody who can really get the job done.” Enter GRAMMY-nominated producer and in-house Taylor Gang engineer RMB Justize. In addition to his star-studded production credits, RMB Justize was also an early adopter of TuneCore: “I’ve been using TuneCore since 2013. Once I realized how simple it became to just release the music, put a cool picture on it, put your name on it, and let the world hear it – it got real.”

In just a few short hours, these total strangers came together to produce a vibey, low-key masterpiece – recording, mixing, and mastering in Studio one, and releasing it on TuneCore without a label ever being involved. For independent artists, the simplicity, efficiency, and financial incentives are simply unbeatable: “Because TuneCore exists, I was able to release music on my own without a record label. And for us, especially years and years ago, that was monumental. For us to be able to just upload and put out music and get some kind of money from it…they gave me the opportunity to monetize off of my music when that opportunity wasn’t really around. And as artists, sometimes we forget that that’s what it’s about. And now we have an opportunity to reach our fans and get some money, so shout out to TuneCore. It’s always love to TuneCore.”

Keyswitching: Potential vs. Reality

Key Switch keys, usually located at the keyboard’s lowest octave, choose different virtual instrument articulations. For example, hitting C0 might add tremolo on a string preset, while hitting D0 adds glisses.

However, presets with Key Switching often require at least a 5-octave keyboard. With a 4-octave keyboard, you usually have two choices: transpose down to cover the notes (which sacrifices the Key Switches), or transpose up to keep the Key Switches but give up some notes. Fortunately, PresenceXT and Studio One deal with this issue in a clever, practical way.

Studio One’s Keyswitch Solution

With PresenceXT, regardless of how you transpose the notes, the Key Switches can always occupy the same position on the keyboard. You can also map Key Switches as desired, and to free up more keys for notes, use only a subset of Key Switches.

To map Key Switches:

1. Open a note event’s Note Editor.

2. Open the Sound Variations panel (click on the Wrench icon at the bottom of the Note Editor’s vertical keyboard).

3. The Action menu (fig. 1) provides multiple shortcuts for altering Key Switch assignments:

• Reload the instrument’s native Key Switch map.
• Assign default Key Switches.
• Assign Key Switches to successive chromatic keys.
• Assign Key Switches to successive white keys.
• Shift (transpose) Key Switches by +1 octave, – 1 octave, +1 note, or -1 note. This function shifts only the Key Switches, so notes remain on the keyboard as assigned.
• Clear all Key Switches.

Figure 1: Click on Action (orange outline) to choose various ways to assign Key Switches.

A Practical Example

The PresenceXT Trumpet Full preset’s notes cover the range C2 through C6 (and even higher). The Key Switches cover the white keys from C0 to B0. You can’t fit 6 octaves of notes on a 4-octave keyboard, so here’s the solution:

1. There are no trumpet notes between C1 and B1. So, shifting the Key Switches to cover the range C1 to B1 avoids overlapping any notes.

2. From the Sound Variations panel, choose Action > Shift Key Switches > +1 octave. Now, the Key Switches cover the range from C1 to B1, with trumpet notes starting at C2 (fig. 2). This gives us three octaves of notes, and all the Key Switches. Compare this to fig. 1, which has different Input notes, and shows the Key Switches mapped from C0 to B0.

Figure 2: A four-octave keyboard can cover three octaves of notes and all the preset’s keyswitches.

3. If you instead want a higher range of trumpet notes that starts at C3, transpose the keyboard up an octave. Then, choose Action > Shift Key Switches > +1 octave again. Now the Key Switches cover the range from C2 to B2, with trumpet notes starting at C3.

Other Cool Key Switch Features

Some prefer having Key Switches on all white keys, because they’re easier targets to hit. Others prefer Key Switches on successive chromatic keys, so more keys are available for musical notes. The Action menu lets you choose either option. Furthermore, you can delete Key Switches simply by deleting the corresponding Input note in the list of Key Switch note assignments.

Note that both VSL and EastWest support Studio One Sound Variations natively, so they work the same way as PresenceXT. In addition to the features described above, when you load a preset, these instruments automatically transmit their Key Switch mapping (including names and symbols) to Studio One. This makes the process of using Studio One’s Key Switching talents even easier.

What About Other Instruments with Key Switches?

Some companies’ instruments (e.g., Kontakt, SampleTank) don’t support the Key Switching protocol that’s part of Studio One’s Sound Variations. But Studio One has a clever way to handle those instruments too—stay tuned for a future tip about this topic.

Finally, Sound Variations are about much more than just simplified Key Switching. To find out more, check out the clear, concise YouTube video by  Lukas Ruschitzka.

Usually, the Vocoder inserts into a track that provides the modulation, and the Vocoder’s sidechain receives the carrier. But why be normal? The same audio that provides the carrier can modulate itself. This technique unleashes a variety of processing options for drums, guitars, keyboards, percussion, and more. Even better, the Vocoder’s controls can tailor the results from subtle, to beautiful, to insane.

It’s difficult to explain the effect in words, so check out the audio examples. The first one has four measures of a loop without processing, then four measures of the loop vocoding itself.

The next audio example has one measure of a drum loop, then the drum loop vocoding itself.

The following example uses chorused guitar, with sawtooth Vocoder band automation to create a “rippling” effect. The vocoded sound goes through reverb as well.

The final example has two static Vocoder matrix settings with guitar. Static settings work well for instrument voicing, like changing the character of polysynth and pad sounds.

Channel Layout

Fig.1 shows the channel layout. This technique inserts the Vocoder in a bus, not a track. The audio track (in this case, Drums) has two pre-fader sends:

• One send goes to the Bus with the inserted Vocoder. This provides the Vocoder’s modulator.
• The other send goes to the Vocoder’s sidechain, to provide the carrier.

Figure 1: Channel layout. The Drums track provides the Vocoder’s modulator and carrier.

Vocoder Parameters

Figure 2: Typical Vocoder settings.

Start with the settings in fig. 2:

• The Carrier Source needs to be Side-chain.
• Shorter Release times add a percussive quality. Longer ones let the sound develop more.
• Mix sets the balance of the carrier and the modulated sound. Mix at 100 gives the most novel effects. Lower Mix values mix in more dry sound.
• Both Send levels from the Drums (or other audio track) affect the sound. Edit the sends to optimize the effect.

Automation, Too!

The vocoder matrix provides an almost unlimited tonal palette. The audio examples capture only a few of the options—just draw on the matrix, and listen to what happens. Also, note that automation can preserve your matrix doodling. Here are three examples of how to use automation:

• Automate the Flip button, and change it on the beat with drums and percussion loops. With the right settings, this can alternate between DJ-style “bottom” and “top” loops.
• Choose Write mode, and use the Vocoder matrix like an Etch-a-Sketch to create various tonal effects.
• Use the Paint tool to add periodic automation (square wave, sawtooth wave, etc.) to the matrix modulation tracks.

Whether used as a glorified tone control, a way to create rippling frequency changes, or to breathe new life into loops, vocoding a sound with itself is can give you new and surprising sounds.

The GRAMMY-winning fiddler, songwriter, and New Orleans native talks about taking his leap.

A life in music requires passion, creativity, dedication – and for many creators, their trajectory can be traced back to a defining moment that changed everything: the moment they took the leap.

Louisiana native Louis Michot is the fiddler, songwriter, and lead vocalist for the GRAMMY award winning Lost Bayou Ramblers. With more than 20 albums under his belt – and a passion for Louisiana French, local folklore, and environmental sustainability – Louis’ music career both honors and pushes the boundaries of the Louisiana French music traditions.

Watch as Louis performs his track “Les Beaux Jours” (“The Good Days”) through the all-new PreSonus Quantum ES 2 audio interface, and shares his story about growing up with Cajun music, his role as a cultural ambassador, and taking the leap with his first solo album.

Louis Michot might be best known as the fiddle player and lead-singer of the Lost Bayou Ramblers – but what truly fuels his career as a musician is Louisiana French, local folklore, and sustainability in the fastest disappearing landmass in the world: “Louisiana is beautiful and complex, both geographically and culturally,” Louis says. “The diversity of cultures that are intertwined here have given birth to some of the most popular music in the world, and the ever-changing landscape inspires people to keep creating new expressions: from Zydeco to Mardi Gras Indians, Cajun to country, and everything in between.”

Growing up surrounded by Cajun music seemed “normal” to Louis. “I thought every kid had an older generation around that played accordion and fiddle music and sang in French. But when I started playing guitar at 12 years old and learned all the Rock’nRoll and Blues standards, I realized that the Louisiana French music my family plays was very different from popular music.” 

Recognizing his unique cultural inheritance, Louis decided to get out into the world and learn French and the fiddle for himself. “I traveled and hitchhiked throughout South Louisiana and Eastern Canada, learning the language with every French speaker I could meet, and honing my skills on the fiddle by playing on the streets.”

Inspired by his experiences at home and abroad, Louis started playing standup bass with the family band before taking the leap and founding the GRAMMY-winning Lost Bayou Ramblers with his brother, Andre. “After a decade of pushing the traditional music to the edge, we started melding the Cajun music we grew up with, and the Rock’n’Roll we learned to love, and playing Louisiana French music in a way that truly inspired us.”

23 years and two GRAMMYs later, Louis decided it was time for another leap of faith, and began work on his first solo album. “When I finally decided to dedicate myself to releasing a solo album, it was because I needed to get this music out of my head and my heart, and wanted to explore the scary freedom of starting with an empty canvas and making something brand new and completely unique to me.”

Hot on the heels of his hurricane relief work, Louis set up shop in a dry-docked houseboat affectionately named “Sister Ray,” and started tracking the songs that would go on to become his first solo album, Rêve du Troubadour (The Troubadour’s Dream). For Louis, the personal and artistic significance of this effort cannot be overstated: “I felt like I was fulfilling a part of myself that was in my blood, part of my heritage, and I want others who feel that same yearning to be able to follow that feeling and keep their culture alive, whatever that means to them.”

“I definitely never set out to represent anything other than myself, but I think my passion for the music and language have led me to be a representative for the importance of cultural depth in Louisiana. I’m continuing tradition within the music and the family, and doing my part to preserve and grow these cultural expressions of Cajun and Creole music.”
