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.

Read full description

Anima is a physical modeling instrument. Sound happens the way it happens in the physical world: a breath excites an object, and the object rings out into a room. That is the whole interface, left to right: ENERGY, OBJECT, ROOM. The object is a modal resonator: twenty-four coupled resonances per voice whose frequencies, loudness, and decay follow physical laws you bend with the controls. Make it wood, glass, or metal. Stretch its partials from strings through piano wire into bells. Touch it at the edge, or hollow it out at the center. Blow at it, press it, strike it with a mallet that hits harder the higher you raise it. Push Inertia far enough and the note ignites and sings on its own breath. The controls are bold glyphs, shapes whose form is the value. No numbers at rest: the panel is a picture of the current sound, and it glides into a new shape when you load a preset. On an iPad the three sections share the screen; on an iPhone they sit side by side, a swipe apart, with the ribbon always under your fingers. Every control is easy to grasp and none of them stop at what the label says; finding what else a knob can do is part of the instrument. The ROOM is a morphable space: Size sets the echo's time, Regen goes all the way into self-oscillation, and Blur melts the repeats into a wash. Delay at one end, reverb at the other, one knob between them. Because every mode frequency is computed from the note, nothing ties Anima to the usual twelve pitches: it plays any tuning an MPE controller can send. Anima is the companion instrument to Hexatone; route Hexatone's MPE into it and per-note microtuning just works, with no configuration. - Standalone app and AUv3 instrument (AUM, Logic, GarageBand, Cubasis, Loopy Pro), on iPhone and iPad; your sound saves with the session - MPE with zero setup: per-note pressure is breath (press into a note and it can ignite), and the slide axis goes wherever you route it, any mix of the ENERGY and OBJECT controls, per note - Every control answers a fixed MIDI CC, so any hardware controller reaches the whole instrument with no mapping; pick a MIDI channel in the app, or play on all of them - Sustain pedal (CC64), MIDI Program Change, Glide, and 1 to 64 voices (at 1 it is a true mono synth) - A ribbon keyboard for true microtonal play (multitouch, per-finger glide, Hold to build chords, Snap or Loose), and a piano with properly wide black keys when you want the familiar - 55 factory presets in banks, including packs by Red Sky Lullaby and Hoavi; save your own, or copy any sound as text and send it to a friend - Undo and redo for every gesture, and the full manual lives inside the app - Collects no data; nothing leaves your device One purchase, iPhone and iPad. Headphones or a real speaker recommended: the low end of the breath is real.
