Spreadsheets Synth vs Drum Rack

The 303 lives between the sheets. Spreadsheets Synth is an acid bass synthesizer with a built-in step sequencer — a cultural product of the band Spreadsheets, tuned to 313K and pointed straight at the dance floor. THE SQUELCH Sawtooth or square through a resonant filter with cutoff, resonance, decay, and accent — from rubbery basslines to screaming acid leads. Add distortion for grit, then send it into orbit with the phaser and delay. THE SEQUENCER Program patterns step by step, set the line looping, and ride the cutoff live. It's an instrument for performing, not just programming. PLAYS WITH YOUR WHOLE RIG • AUv3 plugin — load it as an instrument in GarageBand, AUM, Cubasis, Loopy Pro, and any AUv3 host • Standalone app with background audio • MIDI in and out, including Bluetooth MIDI NO STRINGS No account, no ads, no tracking, no data collected. Just voltage.

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.
