Wind Chimes is a generative MIDI instrument built around a physically simulated row of wind chimes. A simulated wind field sways the chimes, and when two collide, the struck one fires a MIDI note. Play it by hand, or let the wind play on its own. REAL WIND, REAL COLLISIONS • Up to 16 chimes hang in a graduated row • Chimes ring by knocking into each other, not a clapper • Tap, hold, or drag any chime to play it by hand • Gusts sweep across the row instead of hitting all at once CUSTOMIZE EVERY CHIME • Choose anywhere from 2 to 16 chimes • Spread the row from tightly packed to wide open • Length and Weight shape each chime's swing and reach • Go full screen for a bigger, more zen performance A GENERATIVE MIDI PLAYGROUND • Every chime's note comes from the current key and scale • Turn any chime's note off, or reassign it freely • Every chime's real swing angle can drive generative CC modulation • Up to 16 chimes across up to 16 channels, endless generative variety MAKE IT YOURS • Pick from a set of beautifully designed visual themes • Switch between Free timing and a quantized grid • New Wind reseeds the sequence, keeping every setting the same • Randomize rolls a brand-new layout, tuning, and wind in one tap BUILT FOR AUV3 HOSTS • Runs as a full AUv3 MIDI Generator in any compatible host • Automate every wind and tuning parameter from the host • MIDI timing is sample-accurate, synced to the host's own tempo • Presets sync over iCloud across devices, the app, and AUv3 Play standalone with a built-in sampler for instant sound, or load Wind Chimes as a silent-audio AUv3 MIDI Generator and route it into any instrument you like.

Make noise, texture, and percussion sing. Add motion and stereo spread to basic sounds. Load samples and sculpt them endlessly. Leave your mark on any sound with harmonic filtering. Sightlines is a playable harmonic filter. Built from a collection of resonant bandpass filters tuned to the harmonic series, designed to bring out a customizable set of musical frequencies in any sound. Tune it to a fixed frequency like a resonator, or send it MIDI to make it come alive as an instrument. Sightlines can be loaded as an instrument or an audio effect. As an instrument, use it with samples, noise, or oscillators to construct sounds never heard before. As an effect, add movement and interest to any sound, and even impart tonality onto unpitched input. SOUND SOURCES • Noise – filter variable color noise and random noise bursts for Sightlines’ simplest and quickest output. • Samples – send samples through resonant filters as one-shots or infinite looping versions of themselves, great for found sound and tonal samples alike. • Synth – skip the filters entirely and use Sightlines as a harmonic synth, where you can customize and modulate the proportion of each harmonic in the signal. • Audio effect – use Sightlines as an audio effect on any track. MOVEMENT AND EFFECTS • Manipulate overtones – stretch, bend, and reimagine the harmonic series to retune Sightlines’ output into realistic or indescribable sonic spaces. • Quantize frequencies – snap all of Sightlines’ filters to a scale, to impart that key quality onto any sound. • Balance bands – maneuver through the harmonic space by scanning, tilting, or spreading Sightlines’ bands. • End of chain – make your output shine with a built-in chorus, BBD-style delay, and reverb. FEATURES • Modulation – modify any control in Sightlines with multiple LFOs, sequencers, smooth random sources, and performance effects. • Presets – full preset control over every parameter in Sightlines. Cross-platform preset format for sharing with friends. • Waymaker – connect to Sightlines’ sibling application, Waymaker, for direct sequencing of Sightlines’ without MIDI routing. Also available for macOS and Windows in VST3 / AU / AAX formats from Aqeel Aadam Sound.
