DOOM LOOP is a stem-based loop machine built from the Doom Cougar catalog. Seven channels โ kick, bass, snare, hats, acid, perc, and FX โ 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 โ Crease, Creature, Hematoma, Mothers Milk, Parlor Floor, Savage Wit, Shag Chain, Yule, and more - 7 channels โ 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 โ low, mid, high - Independent volume on every channel - Per-channel lock โ protect a loop you like before randomizing - Random โ 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 โ 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.

MAKE MUSIC BY TOUCHING THE MACHINE Tonkro is a playful music workstation for iPad: part synthesizer, sampler, drum machine, sequencer, recorder, editor, mixer, and DJ performance space. SHAPE ORIGINAL INSTRUMENTS Explore distinctive synth and drum engines through four expressive controls. Each workshop is built to feel immediate: touch the illustrated machinery, hear the result, and let the characters react to your performance. SAMPLE THE WORLD Record through the microphone or import audio. Play one sound chromatically, divide it into untransposed slices, or map multiple samples across keys and pads. Trim, crop, loop, reverse, fade, change speed, transpose, and preserve the original recording with non-destructive editing. FIND RHYTHMS YOUR WAY Seven sequencer personalities turn taps, held notes, patterns, gestures, and playful systems into musical motion. Tempo, transport, MIDI, and recording stay connected, so a sketch can become an arrangement without breaking the flow. RECORD AND ARRANGE Build with eight stereo tracks. Record audio or notes, edit clips and piano-roll performances, overdub, punch, loop, lift, drop, mix, export stems, and save portable project bundles. PERFORM WITH MONSTER DECKS Load two tracks, set beat grids, sync, use key lock, cue points, hot cues, quantized loops, EQ, filters, pitch bend, and the crossfader. Record the performance or print it directly into the tape arrangement. MADE FOR PLAY Tonkro keeps its creative tools visible, touchable, and full of character. It works without an account, advertising, or third-party analytics. Your projects, recordings, and imported samples remain on your iPad unless you choose to export or share them.

Verdict
