EQ Converter vs Drum Rack

This is a simple IOS app to aid in transferring EQ parameters between pro audio devices that use different EQ schemes. Sometimes it is necessary to transpose a Q or quality value to a bandwidth value or the reverse. Nail it with this app.

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.
