EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts

Undae is an optical vibe, the watery and vocal swirl of the late sixties photocell units, rebuilt for iPhone, iPad and Mac. A single slow lamp sweeps a chain of staggered filters, so the notches roll through your tone unevenly instead of moving in a straight line. That stagger is what makes a vibe sound like a vibe and not a phaser. Chorus mode blends the sweep against your dry signal for the classic swirl. Vibrato mode drops the dry signal for a pure, seasick pitch wobble. Voice it to taste. Choose 2, 4, 6 or 8 stages, morph the lamp from a smooth sine to a lopsided ramp, move the sweep centre darker or brighter, and add a touch of feedback for a throatier, more vocal sweep. Set the speed by hand or lock the lamp to your project tempo. Spread it across the stereo field for a rotary style swirl, tilt the tone, then set mix and level. Twelve factory presets get you going, from Classic Chorus and Rotary Wide to Jet Phaser and Seasick, and you can save your own. Use it as an AUv3 audio effect in GarageBand, AUM, Loopy Pro, Cubasis, Logic and other hosts, with host presets, parameter automation and full session state. Or run it standalone with the built in demo bed, your microphone, or a song from your library, and export the processed result. Undae collects nothing. No accounts, no tracking, no analytics, no ads. All audio is processed on your device and is never recorded or uploaded.
