AlphaTheta SLAB: A Pad Controller Built for House Beatmaking

If you've ever tried chopping a disco loop or programming a four-on-the-floor groove entirely with a mouse, you know how much feel gets lost in translation. AlphaTheta's new SLAB controller — built in collaboration with Serato — aims to put that tactile element back into electronic music production.

What it is

SLAB is a Serato Studio-native MIDI pad controller created by AlphaTheta in close collaboration with Serato, putting sampling, sequencing, and performance directly into the producer's hands. For house producers especially, that's a meaningful shift — house music lives and dies on groove, swing, and the feel of a sample chop, and SLAB is designed around exactly that workflow. AlphaTheta

Key features for house production

• 16 velocity-sensitive pads with aftertouch for finger-drumming basslines, hi-hat patterns, and that classic chopped-vocal house sound
• Full stem separation — extract and use up to 16 of the best parts from any sample, with adjustable key shift, time stretch, and playback controls for each part, perfect for flipping disco and soul samples into fresh house loops AlphaTheta
• Built-in step sequencer — create and edit drum patterns with real-time control over step velocity, timing, swing, and grid settings, ideal for dialing in that subtle off-grid swing house grooves are known for AlphaTheta
• Automatic key and BPM detection that keeps tracks in sync even as changes are made on the fly, powered by Serato's Pitch 'n Time algorithm AlphaTheta
• Stems Level control for isolating and blending vocals, bass, drums, and melody live — great for building house tracks around a single killer vocal hook
• 190+ built-in instrument sounds spanning bass, keys, synths, and percussion

Why it matters

The standout hook: as soon as SLAB is plugged in, the full version of Serato Studio unlocks for free, removing the usual paywall between hardware and software. It also doubles as a controller for Serato Sample and an accessory for Serato DJ Pro, with a MIDI mode that switches into custom mappings for Ableton Live, FL Studio, or Logic Pro — so producers aren't locked into one ecosystem.

Physically, it's smaller than A4/US Letter size, with a 2-tone gray design and AlphaTheta's signature circular CDJ-style PLAY/REC buttons, making it easy to fit on a desk or take to a friend's studio session
