BEATSLOTS

Spin · Select · Create

A slot machine for trap grooves. One spin and eight lanes land on a beat — 808, kick, snare, rolling hats, clap, lead — in key, in tempo. Keep what you like, re-spin the rest, and drag the tracks straight into your DAW.

Beatslots — eight lanes of waveforms, SPIN ALL TRACKS, CLEAR ALL, EXPORT ALL TRACKS
How it works

Three gestures.
No menus.

Beatslots is built to find an idea in seconds, not to program one patiently. Everything that slows the spin down is a defect.

01

SPIN

One button. Eight reels stop one after the other, each on a sound, a pattern and an effect chain that fit together — in key, in tempo.

02

SELECT

The kick is right, the hats are not. Re-spin a single lane and keep the rest. Mute, solo, tweak a level. Star it as a favourite — no name asked.

03

CREATE

Drag any lane — or all eight — straight into Ableton, Logic or FL Studio as audio. The loop is rendered on the gesture, warm reverbs included.

Built for trap

Made for trap.
From the 808 up.

Every part of Beatslots was shaped around one kind of music. The 808 sits at the bottom of the key. The hats roll. The snare cracks on 3. Nothing here is generic.

808 & bass

Tuned to the key, always

The 808 lane follows the project key. Notes slide into each other the way a real 808 does. And a built-in 808 frequency guide shows where your sub actually lands — C1 to G1 is the sweet spot for clubs and cars.

Kicks

Sample, synth — or both

Play a kick from a sample, or build one by synthesis. Or layer a synth sub under a sampled kick on the same lane, for the weight a sample alone never has.

Hi-hats

Rolls, down to 1/64 and triplets

Each lane has its own rate — 1/8, 1/16, 1/32, 1/64, triplets included — so the hats can roll while the kick stays put. A roll lane per step turns any hit into a burst.

Snares & claps

Pitch and weight per hit

Every step carries its own pitch, its own loudness, its own pan. Template B puts a clap next to the snare so the backbeat has two voices from the first spin.

Half-time & repeat

The drops, built in

A half-time effect for the switch-up, and a rhythm shaper that repeats or retriggers on every hit — the pumping, stuttering movement that makes a trap beat breathe.

Key & tempo

C minor at 145, out of the box

Set once, everything tuned lands in key. Change the key or the tempo and the whole groove follows — 808, lead and chords together. Percussion is left alone, as it should be.

Sample or synth,
on every lane.

A kick played from a file and an 808 built by synthesis live on the same grid, in the same groove. Not two instruments side by side — one.

◐

Eight lanes, hybrid

Each lane is a sample or a synth voice. Kick, snare, hat, open hat, lead, lead or clap, perc, FX — two track templates to start from.

⟳

Spin, re-spin, clear

Spin everything or one lane. Clear it all and start again. Every result is in the project key and tempo, so it always fits.

▤

Two templates

A — Kick, Snare, Hat, Hat, Lead, Lead, Perc, FX. B — the same with a Clap in place of the second Lead. Pick one, it stays yours.

★

Favourites

One click parks the whole groove. No dialog, no name to type — the name is made for you from tempo, key and time. Three slots, always on screen.

⤓

Drag & export

Drag a lane into your DAW, or export all tracks as separate audio files, 32-bit float. The loop closes on itself — reverbs and delays are warmed up first.

▣

Plugin or app

VST3 and Audio Unit inside your DAW, or a standalone app on its own. macOS and Windows. One licence covers both formats and both platforms.

Your key arrives by email right after the purchase. It looks like WTKP4-66NL5-HMKQW-GFSCZ.

1

Open the licence window

In Beatslots, open the ☰ menu at the top right and choose License…. It also opens by itself while the demo is running.

The window turns green. From now on this computer opens without asking, with or without internet. Moving to a new machine? RELEASE THIS COMPUTER frees the slot.

Questions

The short answers.

How many computers can I use one key on?

Two. A studio Mac and a laptop, say. To move to a third, open the licence window on one of the first two and click Release this computer — the slot is free again.

Does it need an internet connection?

Once, to activate. After that Beatslots works fully offline. When it does have a connection it quietly re-checks the licence every 30 days; if it can't reach us, nothing changes on your side.

Which formats and systems?

VST3 and Audio Unit for your DAW, plus a standalone application. macOS and Windows. One licence covers all of it.

Is the demo the same software?

Yes — the very same download. The demo plays everything, but a short noise returns every 30 seconds, you get 10 spins per session, and drag and export are closed. The key removes all three, instantly, without reinstalling.

I replaced my computer and can't release the old one.

Write to hello@mpesynth.com with the email you bought with. We'll free the slot by hand.
