Konstrukt is a patchable instrument for iPad and iPhone. Design the surface you play, sequence it, give it sound with built-in instruments and your own AUv3 plug-ins, mix and record it — and when you want to go deeper, unlock the visual graph underneath and rewire all of it. Standalone, and as an AUv3 in your host. SURFACES YOU DESIGN • The KB-1 keyboard suite — piano, diatonic chord pads, scale-locked keyboard, MPE Seaboard ribbon, MPE Strings grid (4ths) and a 4×4 drum-pad grid, each with an arpeggiator. Successor to the KB-1 Expressive Keyboard Suite. • Knobs, faders, XY pads, buttons, live visualizers and channel strips on a snapping grid, in pages like hardware banks. Bind any control to MIDI CC — or, with the unlock, to any parameter in the patch. A SUITE OF SEQUENCERS • Drum, melody, chord, analog and CC lanes, the Drum Grid, a Metropolis-style Stage Seq and a Matrix note grid — tap to edit, with per-step velocity, probability, trigger conditions, ratchets and microtiming. • Patterns up to four bars, eight banks per lane. Record into patterns step by step or live, then fix it in the grid. A Looper with quantize, undo and expression capture. • Players: one tap on a lane writes a pattern from a style and a Complexity slider — drums with fills, a bass under your chords, chord stabs and pushes. • One patch key and scale every lane can follow, custom scales, and chord lanes with their own rhythm layer. INSTRUMENTS AND YOUR PLUG-INS • Built in: a two-oscillator Synth, a Wavetable synth, Drums, MegaSaw, a Sampler and a loop Slicer, plus Drive, Filter, Delay, Reverb, Compressor, EQ, Chorus and Phaser — each with its own panel. • Host your AUv3 instruments, effects and MIDI effects inside the patch (standalone app), with floating plug-in windows, presets and bindable parameters. THE RACK • A strip per instrument: fader, pan, mute and solo, inserts, pre- or post-fader sends to bus strips, sidechain, MIDI Learn, master inserts, and scenes recalled with a fade. Hardware synths join as External Instruments. • Bring a mic or guitar in on its own channel. Record the master and stems to 24-bit WAV. Tap tempo, metronome with count-in, Ableton Link, MIDI clock in and out. Multi-output routing on a multi-channel interface. UNLOCK — THE GRAPH EDITOR (in-app purchase) Everything above runs on one visual graph that carries MIDI and audio. Unlock the editor to rewire it: • 80+ node kinds — arps, scale quantizers, chords, echoes, swing, euclidean rhythms, LFOs and CC tools, wired MIDI In → processors → instruments or MIDI Out. • Components — save a cluster of nodes as one card with real ports, its surface cards included; drop saved components into any patch and edit them inside. • Audio on the same canvas — cable instruments through effect chains and hosted effects, split sends to buses, key a sidechain. The Rack is this graph seen as strips. • Emergence generators — Game of Life, Turing machine, Wolfram rules, Markov chains, bouncing balls, a Lorenz attractor — patterns that evolve instead of loop. Every keyboard is a routable node, every knob can drive any parameter. Factory graph patches open and play without the unlock. The unlock is the editor and nothing else. WITH HARDWARE, OTHER APPS OR A DESKTOP DAW • MIDI out over CoreMIDI, extra output ports and an always-on virtual port: 16 channels plus MPE. • One USB cable to a Mac, or Bluetooth MIDI — two MPE surfaces and a controller that reshapes per track, no driver needed. • As an AUv3, load Konstrukt as a MIDI processor or as an instrument in hosts such as AUM, Logic Pro, GarageBand, Cubasis, Drambo and Loopy Pro. PRICING One-time purchases, no subscription. The app is the whole instrument; the graph editor is a single optional unlock. One purchase covers iPad and iPhone. Requires iOS 17 or iPadOS 17 or later; on iPhone the app runs in landscape. Plug-in hosting, audio input and recording are part of the standalone app. No user data is collected.

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.
