MAKE BETTER MELODIES
WAY FASTER.
Title

Heavenly synths. Buttery leads. Snappy one shots. Chaotic textures.

I didn’t follow the rules—I flipped the formula. I spent months bending every LFO and dialing in every detail in Serum 2 to make presets that came alive. The moment you load up these sounds, you’ll hear it: that spark, that bounce, that edge you’ve been looking everywhere for. I made Butter so you can wake up your creative side and fall back in love with producing. Be careful. Every patch is weirdly addictive.

Drag-and-drop 100+ Serum 2 Presets and 100+ one-shots

100% royalty-free — safe for placements, YouTube, beat sales, and sync.

Unlock the BUTTER sound— it's your shortcut to standing out.

But... what's inside BUTTER?

"BUTTER"
SERUM² BANK

I spent countless hours on this bank—it’s not your usual batch of generic Serum sounds. It’s full of texture: glossy, crackly, watery, and even some instruments you rarely hear in synths. Blended stuff like strings, flutes, and brass with digital weirdness to create something that feels alive and unpredictable. (100+ presets)

pluck - stimulate

key - quartex

bass - fedora

lead - krimpet

pad - ashman

string - fillout

lead - tumfbox

key - cookout

brass - friendly

key - dixiecrash

key - shimmy

hold - titanium

"BUTTER"
ONE SHOT KIT

100+ buttery, high-quality one-shots rendered in both high and low octaves straight from the Butter Serum Bank, so they stay crisp for things like slide notes and won’t limit your creativity. I spent extra time exporting them carefully—since Serum plays slightly different each time, I captured just the right amount of randomness to keep every one-shot feeling organic.

pluck - liquimox

lead - doy

bass - luigi

pluck - tumfool

brass - ford

flute - character

string - yoshi

synth - waterworks

bass - icechain

lead - score

key - preesh

key - plinko

"SIZZLE" MIDI COLLECTION

These MIDIs are meant to sit in the background and do their job—but they’ve got enough character to shine if you bring them up front.  Tweak a few notes or leave them as-is. I called it Sizzle because they’ve got that sauce that pulls everything together. They’re perfect for quick, 2-minute melodies that actually sound good. (50+ starter midis included)

"HONEY" LOOP KIT

Made these loops spontaneously while sound designing presets—so they’ve got this cool raw emotion baked into them. I also consumed an absurd amount of actual butter while making them. They’re super flippable, super drummable— up to you. (23 loops, stems included)

"kindhart" 147 BPM

"gooey tymes" 163 BPM

"change numbers" 153 BPM

"voyage" 154 BPM

"michelin" 175 BPM

"staycation" 193 BPM
