About

Jacquardi4

Read full description

Concept: “Jacquardi4” is an AUv3 instrument that does not make any sounds but can send out 4 analog-like “Envelope” signals via MIDI control changes (MIDI CC). That is, the app contains 4 MIDI modules of envelope generator. The user can use them for modulating any parameter of 3rd-party’s plugins that can be assigned to MIDI CC , for example, cutoff frequency. System Requirements: AUv3 host that has a flexible capability of MIDI routing (AUM, apeMatrix, LoopyPro, etc). Usage: Just assign MIDI keyboard to Jacquardi4's MIDI IN (it needs to trigger Jacquardi4) and assign Jacquardi4's MIDI OUT to 3rd party's plugins. Explanation of sliders: Channel: determines MIDI channel. Control Rate: determines the resolution of MIDI processing. Higher value, higher resolution. Active: turn on or off the module. Useful when using MIDI learn functionality of 3rd party plugin. MIDI CC: determines MIDI control number. (text-editable) Amp: determines amplitude in dB Offset: determines an initial value. Attack: attack value. Decay Time: decay time value. Decay Curve: decay curve value. Sustain: sustain value. Release: release value. Explanation of Preset File System: At first make a new bank folder, in which you can save a preset file. And push "Save As" button. Also the user can export or import preset files.

MNTRP is a drone instrument shaped like a journey: Earth to the Moon and back. A spaceship travels a figure-8 trajectory across the screen, and where the ship stands on that path IS the sound. There are no patches to browse — you play a position in space. THE TRIP The voyage passes through five stages, each with its own synthesis engines: • Liftoff — deep roaring engines, shaking metal • Interstellar — adventurous, airy drift (crossed twice: outbound and homebound) • Around the Moon — dark, mysterious, bowed strings • Reentry — the burn of coming home As the ship moves, the stages blend continuously into each other — a morph, never a switch. FLYING • Drag the spaceship along the path, or move the mission slider. • Or set a flight time (10–300 seconds) and press FLY: the ship flies itself and the sound travels with it. Missions loop — the entered time is one lap. Single-run mode lives in OPT. • The ship's position sets WHERE you are; the keyboard sets what sounds there. Nothing plays until you play. HOLD latches keys for hands-free drones. THE FIVE SHIP SYSTEMS The five big knobs mix the ship's systems, and each system keeps the same role through every stage: • ENGINES — the low floor: rumble, pedal, buffet • HULL — the ship's pitched voice • LSS — life support: the air • NAV — events and markers • COMMS — radio artefacts and telemetry TUNE Twelve shaping knobs under the TUNE panel: CUTOFF, RESO, DRIVE, TILT, TONE, SUB, ATTACK, RELEASE, GLIDE, RATE, DEPTH, SPACE. TRIPS — KNOB AUTOMATION Hold a still finger on any knob for two seconds to lock its value at the ship's current position — a red dot marks it on the knob's arc. Lock two or more points and the knob glides between them as the ship flies, around the full loop with no jump at the wrap. Name your trips, save them, load them. POV Press POV to ride in the cockpit: the Moon approach, the dark far side, Earthrise, the sun with its waving corona. Tilt your device to look around — the scene is a real 3D space in low-res pixel art: parallax stars, orbiting satellites, meteors, a photographed Milky Way. The sunlight follows your tilt, the terminator creeps across Earth and Moon — and at the right angle you can pull the Earth's shadow onto the Moon for an eclipse. AUV3 MNTRP ships as an AUv3 instrument and an AUv3 effect for hosts like AUM, GarageBand and Logic. The instrument is the full trip; the effect flies your own audio through the engines — the host signal bows the Moon's strings and feeds the reentry burn. Full state saving in the host; hardware MIDI in the standalone app. No accounts, no network, no data collected. Just the trip.
