Is the online groovebox free?

Yes. The groovebox plays for free with no signup and no ads. A free account unlocks saving your projects and WAV export.

Can I build a full song, not just a loop?

Yes. In the SEQUENCER tab you PRINT each pattern as a part (intro, verse, hook…), name it, cut and reorder the parts, and play or export the whole song. Each part keeps its own sounds and settings.

Do I need hardware or a download?

No. It is a browser-based groovebox built on the Web Audio API — no hardware, no download, no plugin. It works on desktop and on phones, and you can plug in a MIDI controller if you have one.

Q: What is a groovebox?

A groovebox is an all-in-one instrument that combines drums, a sampler, sound sources, a sequencer and effects in one box, so you can build a whole track without a computer. Shuffle Drummer is a groovebox that runs in your browser: drums, sampler, synth, mixer, FX and a song mode to chain patterns into a full track.

Shuffle Drummer is a free online groovebox: drums with real swing, a sampler, a Minimoog-style synth, a piano roll, a mixer with effects, and a song mode that chains your patterns into a full track. The all-in-one workflow of a hardware groovebox, running in your browser. No download, no plugin, no signup to start.

Online groovebox in Shuffle Drummer: the SEQUENCER tab in song mode with three printed pattern blocks showing kick, snare and hat lanes over six bars, plus PRINT, CUT and SNAP buttons — The SEQUENCER tab: three patterns printed as parts over six bars. This is where a loop becomes a song.

How a groovebox session goes

Drums first. Turn the SHUFFLE wheel to a groove you like, edit the steps, set the swing. Pick a kit in the DRUMS BANK.
Add a sample or a chord. Chop a loop in the SAMPLER tab and play the slices on pads, or play a bass line and a pad on the synth in the PIANO tab.
PRINT the pattern. In the SEQUENCER tab, PRINT captures the current pattern as a part. Change the drums, mute the sample, switch the synth preset, PRINT again: that is your second part.
Arrange. Name the parts (INTRO, VERSE, HOOK…), CUT and reorder them, set the total bars, and play the whole song from the top.
Mix and export. Master EQ, bus compressor and tape on the MASTER tab, then export the sequence as WAV, share the full song as a beat card, or publish it to the TOP BEATS gallery.

Everything a groovebox should have, in the browser

Hardware grooveboxes put drums, sounds, sequencing and FX in one box so you can build a whole track without a computer. Shuffle Drummer brings that same all-in-one feel to the web, free:

Drum engine — 6 drum tracks, synthesized drums plus sampled kits, a shuffle wheel of hand-made grooves, swing from 50% to 75%, per-step velocity, off-grid timing (online drum machine)
Sampler — load and chop your own sounds into up to 64 slices, pitch them, remove the drums from a loop, play the slices on pads (online sampler)
Synth and piano — a Minimoog-style synth with 96 presets and a sampled piano, on up to four piano-roll tracks
Step sequencer — 16 steps per bar, 2 to 8 bars, grid from 1/8 to 1/32, 96 PPQ timing
Song mode — PRINT patterns into named parts, cut, reorder, play the full track; each part keeps its own sounds, filters and synth preset
Mixer and FX — 8 channels with EQ and filters, 5-band master EQ, SSL-style bus compressor, tape emulation, limiter, reverb, delay and 16 master FX pads
Export and sharing — WAV stems and master, MIDI file, full-song MP3 share card, one-link sharing with remix, TOP BEATS community gallery
MIDI in — pads, keys, pitch bend and mod wheel from any controller or an Akai MPC (Chrome and Edge)
