This isn’t a friendly 808 pack.
This is low-end possession.
MPC 808 P$YCHO KNOCK Xpansion is a fully formatted MPC Expansion engineered for producers who want their beats to sound dangerous, unstable, and unapologetically hard.
Memphis darkness.
Atlanta pressure.
Dope boy energy wrapped in sub frequencies.
This is a true MPC Expansion, not a random folder of sounds.
Professionally structured. Browser-ready. Instant load.
Fully compatible with:
MPC Live
MPC Live II
MPC X
MPC One
MPC Key 61 / Key 37
MPC Studio
MPC Software (Desktop)
Install it → Open your Expansions tab → Load → Knock.
No mapping. No tuning. No guesswork.
50 Tuned 808 Bass Keygroups (.Keygroup.xpm)
Fully mapped across the keyboard. Glide-ready. Slide-ready. Sustain-ready.
Raw 808 Wave Files Included
The original waves are included so you can distort them, stretch them, reverse them, or build your own layered monsters.
Sub Frequencies Built To Rattle Structure
Designed for:
Trunks
Club systems
Dark studio sessions
Late-night headphone paranoia
These are not soft sine 808s.
These are:
Long sustain demons
Distorted low-end tyrants
Midrange knock bruisers
Sub bass that feels illegal
Each 808 was:
Precisely tuned across keys
Balanced for glide movement
Crafted to stay clean — or break speakers when pushed
Designed to slice through aggressive trap drums
This is that:
Memphis alleyway tension
Atlanta block pressure
Midnight studio menace
Most 808 packs sound recycled.
Safe. Predictable.
This Xpansion feels unstable.
Every note carries weight.
Every slide feels threatening.
Every drop sounds like something is about to happen.
If your beats feel soft…
If your low end lacks fear…
If your drops don’t shake walls…
MPC 808 P$YCHO KNOCK Xpansion was built for you.
Dark.
Sinister.
Speaker-breaking.
Load it — and let the subs speak.
