Technobabble: Synchronous polyphasic temporal compression for the coherent transsubstantiation of the phase-modulated frequency spectrum into a cross-dimensional, entropy-resistant acoustic singularity... to put it in simple terms: a baryonic resonance oscillation with fractal phase inversion that deconstructs the continuous time vector within the Hilbert space, freezing it inside an infinite, dimensionless audio event horizon. JAX Kryostatic is an AudioUnit (AUv3). AudioUnits require an audio host application. We produce audio tools exclusively for Apple platforms. The audio effect processor freezes your audio stream in real time. At the heart of its visualization lies an energy correlometer, alongside a dual stereo FFT waterfall display with adjustable flow speed. Using a "Touch and Slide" interface, you can intuitively freeze and shift the live stream's spectrum, visibly - even into extreme ranges. The freezing effect itself is automatic or freely adjustable, ranging from "Soft Iced" to "Hard Iced." So JAX Kryostatic serves equally well as a creative tool for sound design or simply as a musical analysis utility. This AudioUnit is highly optimized for real-time audio processing and very low CPU usage, as its entire graphical visualization is de-coupled and calculated / rendered directly on the GPU. Our new concept involves releasing some of our fully produced songs alongside our FRONTIER SERIES Audio Units. In doing so, we aim to illustrate our new guiding principle: providing musical tools rather than chasing obscure trends of noise production.

No sequence. No play button needed. An instrument that keeps going without you programming anything. Two generative engines invent phrases endlessly inside the scale and chord you choose. What you shape is not a song — it is a way of sounding. Move a control and the sound changes shape without ever stopping. Density, contour, filter, tape movement. It is built so that nothing you touch can break it. And you can play it. On the key pad or from a MIDI keyboard, right on top of the stream it is generating. What you play can be captured into the looper. Now your own sound can go in too. Record a bar into SAMPLE, the fifth machine, and chopping it up and rearranging it is the app's job. ■ Generate • Two independent arpeggio engines (waveform, filter, envelope, effects) • Ten arpeggio types (including Fingerpick, fingerstyle guitar), chord progressions, ten time signatures • BASS — a bass machine of its own (STEP / COMPLEXITY / OMIT / PATTERN) • Drum machine • Six LFOs, XY pad, performance FX ■ Slice (SAMPLE) • Record one bar from a mic or line input, with count-in and click • Record the app itself (ARP A / ARP B / drums), and overdub onto it • Load audio files — and the audio from a video file • Up to 32 slices, ordered by the same rules as the arps: direction, reverse, octave, probability, groove • STRETCH (on by default) — change tempo without changing pitch • Its own filter, envelope and delay / reverb sends ■ Play • On-screen key pad — always in scale • MIDI keyboard input (damper pedal, pitch bend, standard control changes) • One-bar looper that records how hard you played ■ Sound • Piano — three velocity layers, stereo, damper release • Electric piano — harmonics shift with how hard you strike • Nylon-string guitar — synthesised with a physical string model • Marimba, kalimba, handpan and chime — struck instruments, measured from the real ones and synthesised • Waveforms (sine / triangle / saw / square) plus an acid filter • Delay, reverb, Glitch, Granular, overdrive • DRIFT / FLUTTER — tape movement on the synth voices and the live input alike • Concert pitch A=415–444 Hz ■ Connect • AUv3 plug-in — as an instrument and as an effect • Ableton Link, MIDI Clock, MIDI out (ARP A / ARP B / BASS / DRUMS), LFO as MIDI CC • External audio input (line / microphone) • WAV recording and export One-time purchase. No subscription.
