DoomLoop vs Bitbop

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.

Make music with your thumbs. Bitbop is a tiny chiptune groovebox - tap the colored pads to drop notes into a song while a little 8-bit band grooves underneath you: melody, bass, sparkle and drums. Here's the magic: every pad is in key, so you literally can't play a wrong note. Beginners make something that sounds great in seconds. There's nothing to read, no menus to learn - just tap and it grooves. FIVE SOUND ENGINES, NOT FIVE PRESETS Every mood is its own synthesizer, written from scratch: - BitBop - the signature chiptune voice: PWM lead and chip-supersaw - Rave - detuned supersaw and a saw reese bass, straight off a warehouse floor - Handheld - a faithful 4-channel console chip, real LFSR noise and all - Classical - plucked Karplus-Strong strings in a procedural hall - Dancehall - syncopated sub-bass, skank chop and a steppers riddim 600+ TUNES TO START FROM Load a public-domain classic, a folk tune, a rag, an anthem, a rave groove or an original chiptune sketch - then pull it apart and make it yours.
