DoomLoop vs Drum Rack

DOOM LOOP is a stem-based loop machine built from the Doom Cougar catalog. Seven channels — kick, bass, snare, hats, acid, perc, and FX — each loaded with eight loops pulled from real Doom Cougar tracks. Tap a pad to bring that loop in. Tap another to swap it out on the next bar. Everything stays at 138 BPM. Everything stays in time. There is no beat-matching, no syncing, no waveforms to wrestle with. The tempo is fixed. The bars are fixed. The loops swap clean. WHAT'S IN IT - 56 loops from the Doom Cougar catalog — Crease, Creature, Hematoma, Mothers Milk, Parlor Floor, Savage Wit, Shag Chain, Yule, and more - 7 channels — one loop at a time per channel, plus a one-shot FX channel for stabs and vocal hits - 138 BPM master tempo with every stem pitched to match - 3-band EQ on every channel — low, mid, high - Independent volume on every channel - Per-channel lock — protect a loop you like before randomizing - Random — roll the dice on every unlocked channel, queued to the next bar - Bar / beat indicator with 4-LED beat readout HOW IT WORKS Tap a pad to load that loop. If a channel is already playing, the new pick is queued — it swaps in clean on the next downbeat. No bumps. No dropouts. No drift. Lock the channels you want to keep. Randomize the rest. Walk a track from a stripped-down kick-and-acid groove into a full mix and back without touching the play button. This is Doom Cougar's catalog, taken apart and handed back to you. Build new tracks. Wreck old ones. Nothing here gets out of time. 138 BPM. 7 channels. 56 stems. One bar at a time.

Drum Rack builds every sound from scratch. There are no samples in this app — the kick, snare, hats, clap and toms are synthesised as you play them, which is why a kick can drop from 200 Hz to 49 Hz along a curve you draw with your finger. WHAT IT DOES Seven synthesised voices — kick, snare, closed hat, open hat, clap, low tom and high tom — each with its own controls. Draw the pitch envelope of the kick and the snare by hand: drag a point, add a point, bend the curve between two points. Watch the rendered waveform change as you go. A 32-step sequencer with per-step velocity, timing nudge and ratchets, so a single step can hold a roll of up to eight hits. Time signatures from 3/4 to 7/4, grids from 1/8 to 1/32 including triplets. Swing that knows it does not belong on a triplet grid. Eighteen genre presets, from house and techno to jungle, boom bap and reggaeton. Each one loads a full kit and a pattern to start from. Export a loop of 1, 2, 4 or 8 bars as a WAV file, cut sample-exact on the bar so it loops seamlessly in any DAW or looper, or export the pattern as MIDI. The MIDI carries velocity, nudge, ratchets and time signature, and lands on the General MIDI drum map — drop it on a drum rack in your own DAW and it plays on your own kit. WHAT IT DOES NOT DO No account. No sign-in. No advertising. No analytics. No tracking. Your patterns stay on your device. Nothing is uploaded. FROM THE LAB Drum Rack is part of Lumlux Art Lab, a set of free browser tools for people who make music. The same drum machine runs on the website, so you can try it before installing anything.
