Tip: Click to toggle on/off. Click on Hi-Hat notes repeatedly to cycle rolls: 1x → 2x roll → 3x triplet → 4x sizzle!

The Memphis Bounce

Memphis rap and Tay Keith production relies on dynamic syncopation: the snare snaps reliably on beats 3 (step 9 in half-time), while the kick and tuned 808 leave breath, dodging each other to avoid low-end mud.

Hi-Hat Ratchets & Rolls

Standard 1/8th note hat pulses gain energy through ratchets: rapid subdivisions (double-time 1/32nd or triplet 1/24th rolls) inserted right before snare accents to build tension and momentum.

808 Glide & Sub Tuning

Our synthesized 808 engine couples a fast punch pitch envelope (from 140Hz down to 42Hz) with pure low-frequency saturation, letting sub-bass translate across phone speakers and car subwoofers alike.

Frequently Asked Questions

How does the audio synthesis work without sample files?

All instruments are generated in real-time using the native HTML5 Web Audio API. The 808 uses frequency-modulated sine oscillators, the snare and clap combine noise generators with shaped bandpass filters, and the hi-hats use metallic clustered square-wave filtering.

Are the exported WAV loops royalty-free?

Yes! Any beat pattern you sequence and export through the WAV loop generator is rendered directly in your browser. You own 100% of the audio loops you synthesize for use in your DAW (FL Studio, Ableton Live, Logic Pro, etc.).

How do I program hi-hat rolls and triplets?

Click any active step on the Sizzle Hat track. Each click cycles between normal (1x), double roll (2x), triplet roll (3x), and rapid 4-step ratchet (4x), indicated directly on the grid cell.
