Generate drum MIDI with controlled chaos.
ZombieCoffee builds drum, percussion, and sample-trigger MIDI with controlled randomness, humanization, and deep timing resolution.

- Dial in tight hats, ghost hits, glitch fills, and long-cycle percussion patterns.
- Created MIDI works with any DAW that supports standard MIDI files (FL Studio, Ableton Live, Logic Pro, GarageBand, Cubase, Studio One, Reaper, Bitwig Studio, Pro Tools, Reason, and more).
- A standalone app, not a plugin. No cloud workflow, no subscription.
$14.99 USD one-time purchase. No subscription.
HEAR THE DIFFERENCE
The same groove, before and after ZombieCoffee. Before is a short rhythm programmed in FL Studio and looped. After is the same rhythm rebuilt in ZombieCoffee with velocity variance, a stronger downbeat, timing drift, note variation, and a longer phrase.
Before: hand-programmed loop
After: ZombieCoffee
BUILT FOR ELECTRONIC RHYTHM DESIGN
From straight grooves to unstable glitch
Build hats, shakers, percussion layers, and transition fills that move from clean and repeatable to broken and unpredictable.
Sample racks feel played, not stamped
Map notes to one-shots and let ZombieCoffee vary pitch choice, velocity, accents, and micro-timing so loops feel performed instead of machine-flat.
Generate variations without losing control
Reuse rhythm parts, layer tracks, and export alternates for verse, drop, breakdown, and fill sections without rebuilding every bar.
USE CASES
- Off-grid hats and shaker movement for house, techno, and drum and bass.
- Ghost hits, accents, and downbeat emphasis for grooves that breathe.
- Randomized one-shot triggering for drum racks, samplers, and note-mapped instruments.
- Polyrhythmic loops and long evolving cycles for experimental electronic production.
- Arrangement-ready alternates for breakdowns, fills, and drop transitions.
- Fast MIDI export for dragging straight into your DAW session.
PROOF OF CONTROL
Works fully offline
Your projects stay on your machine. No AI model, no tokens, no internet dependency, and no subscription layer between you and the MIDI.
Humanize note choice, timing, and accents
Shape how rigid or unstable the result feels with randomized pitch selection, velocity variance, downbeat emphasis, start and end time offsets.
Tiny ticks to long cycles
Go from 1/256-note micro-glitch detail to 8-beat Maxima phrases, with triplets and dotted values in between.

How much does it cost? Is there a subscription?

-
What kind of producer is this for?
ZombieCoffee is strongest for producers building drum, percussion, and sample-trigger MIDI in electronic genres like house, techno, drum and bass, breakbeat, IDM, and adjacent experimental work.
-
Can I use multiple instruments in one idea?
Yes. Create multiple tracks and generate the project. MIDI is generated for the combined tracks and the individual tracks. Map each track to its own sampler, drum rack, or instrument in your DAW. You can also use a specialized plugin that maps notes to samples.
