Particle Music vs EchoSketch

Particle Music is a generative music sandbox where physics makes the song. Drop colored particles into a glass playground, tilt your device — or let auto-motion drive them — and every collision becomes a note. A particle's size picks its pitch on the active scale. Its color is yours. Its voice comes from the layer it lives in. Scatter shaped bumpers across the scene to deflect, accent, detune, filter-sweep, randomize, or echo the sounds that strike them, and a simple still life turns into a composition that keeps unfolding. Four independent layers stack SATB-style, each with its own waveform (morph freely between sine, triangle, square, and saw), subtle pitch drift for choral breath, filter tilt, reverb send, and an octave shift so voices can sit in different registers. What's inside: • Up to 32 particles across 4 voice layers • 6 musical scales plus full Scala (.scl) microtonal import • 6 bumper shapes with spin modes and per-shape audio effects • Per-layer timbre morph, drift, filter, reverb, and octave • Physics you can feel — gyroscope control, edge bounce, collisions, friction, restitution • Preset snapshots to save a configuration and return to it later • Reverb presets from small room to cathedral There's no timeline, no grid, no tutorial telling you what to do. Build a configuration, watch it play, change one thing, watch it play differently. Use it as a quiet background for focus, an ambient companion, or a toy to spark ideas for music made somewhere else. Particle Music is a result of research in the Visual Arts

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
