About

DoomLoop

Read full description

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.
