How Producers Use Kits AI: Inside the Making of “Fancy Feet”

Electronic producer Brett Rosenberg, better known as Beast Coast, has spent the last decade shaping experimental electronic dance music from his minimalist studio in Rochester, NY. In his early days as a producer and composer he found himself often leaning into building chillwave, synth wave, and lo-fi productions, often built around vocal chops that are stretched, blended and warped into rhythmic and creative soundscapes.
His latest release, “Fancy Feet” (May 16, 2025), marks a slight departure from his usual style. Lo-fi drum patterns meet sharper electronic drum patches, creating a sound that feels more spacey and alternative than dance floor ready. Fuzz, drones, and psychedelic layers drift in and out of the mix, pulling listeners into a composition that nods to the nostalgic textures of early 2000’s alt-hip hop sampling while drawing comparisons to the melodic pull of Goth Babe and the experimental edge of Robert DeLong.
Finding a Spark
Brett’s creative process usually starts with a loose idea and a handful of sounds. He builds from carefully chosen synths, percussion, and samples, with manipulation at the center of his approach. His sampling technique often shapes both rhythm and melody, utilizing a number of different platforms from mainstay sampling giants like Splice, to newer AI tools like Kits AI, which expand how sounds can be reimagined within his compositions.
“This track was not driven by any underlying theme. I just wanted to push myself out of my comfort zone, to test the edges of not only my style but even my taste.”
The spark for “Fancy Feet” came from a Splice starter loop. Brett split it into chords, transposed them, and added effects until the sound felt personal. Additionally, Converting everything into MIDI opened the door to new synth textures - but it was creating his own vocal chops that set the tone for the majority of the track. Through constant trial and error with sound processing, a glitched vocal unexpectedly produced the phrase ‘fancy feet,’ a playful fragment that captured the song’s vibe and ultimately gave the track its title. It was strange and playful, but it stuck and quickly became the song's anchor.
Creating Vocal Chops Bending Sounds Through Kits
Trial and error shaped the production. If a sound crossed what Brett calls his “feeling induction threshold,” it stayed. That instinct, paired with the experimental nature of Kits AI, gave the production its distinctive vibe.
Isolating and Manipulating Vocals with Kits AI
Kits AI is a browser-based vocal tool that allows users to clone voices and sing in various styles. Producers can drag in vocal samples and transform them into completely new voices using a library of ethically trained AI voice models, and any content produced with Kits.AI is 100% royalty-free. While many approach it strictly as a vocal transformation tool, Brett pushed it further by feeding in non-vocal material like percussion and bass loops to discover unexpected textures and samples.
On “Fancy Feet” he used Kits AI several times to isolate vocals for manipulation, with each pass creating something entirely new:
A glitched vocal run through the voice changer became the centerpiece of the chorus, hook and new melody.
A lo-fi flute in the bridge was transformed into the “Modern Pop Diva” Voice, adding a ghostly edge.
A warped vocal chop reshaped into the “Tee” Community Voice became a dark ambient layer in the background.
Even the bass line was processed through a voice model. After adding stereo width, it turned into one of the song's most memorable textures.
These weren’t “happy accidents” so much as unexpected discoveries—moments where Kits delivered something Brett never would have imagined on his own.
For producers just starting out with Kits, Brett recommends keeping it simple when experimenting with interesting textures and chops:
“Don’t even open your DAW at first. If you’ve got a fat sample folder of audio clips or a Splice subscription, just drag random clips into Kits and explore. The more you experiment with new sounds, the quicker your ear learns what works. And don’t sleep on the speaking voice models—they’re killer for turning phrases into tonal instruments.”
Weaving Chaos into Structure
Unlike many of his past projects, the music production workflow for “Fancy Feet” unfolded in a straight line. Brett started at the intro and moved forward, letting each section grow naturally into the next.
To sculpt the vocal loop he leaned on Devious Machine's Infiltrator 2. For creating vocal chops he reached for Serato Sample, while the sliding bass line came alive through Minimal Audio's Current.
Other tools added color around the edges: Valhalla Vintage Verb, Output Movement, Sound Particles Energy Panner, FabFilter Suite, Pitch Monster, Lunacy Audio Beam, Process Audio Ripple Effect, UVI Dual Delay X, SoundBetter Butterfly Effect, Minimal Audio Rift, and Goodhertz LoHi.
Vocal Chain and Music Production Tools
The vocal chain for his own vocal chops was central to shaping the song's identity. Auto-Tune, Soundtoys Little AlterBoy, and AVOX Throat formed the backbone of the effects for the chops, with flangers, comb filters, and vibrato layered on top to give the vocals their constantly shifting, psychedelic quality.
Challenges, Breakthroughs, and His Secret Sauce
For Brett, the hardest part of “Fancy Feet” wasn’t building it, but mixing it. Heavy automation across plugins such as Infiltrator and Energy Panner introduced pops, crackles, and noise that Brett had to clean out and automate by hand.
Transitions were another hurdle, especially in the outro. The breakthrough came through the Kits AI Gliding Bass Model. Running the bass line through a male voice model created a warped, one-off sound that could never be replicated, and it became the perfect closing statement for the song.
But the real secret sauce was in the mix itself: instead of grouping select tracks to a bus, Brett slapped two consecutive instances of Infiltrator 2. gating the LFO FX directly on the master bus and automated them across the whole song. It was a risky move—one that could have wrecked the mix—but actually gave the track its driving energy. With the help of Kits AI tools, anyone can automate technical tasks in mixing and mastering, ensuring consistency and quality.
Release and Reflection
Produced, mixed, and mastered in Logic Pro X, the track reached its end game with Newfangled Audio Saturate, which added warmth while still preserving the grit.
Releasing “Fancy Feet” felt different for Brett. “Always feels good, but I had a little more confidence with this one. It is weird and silly, but it works.” Early reactions praised to the track’s glitch aesthetic and consistent movement.
