Body, air, and string detail — the shape of a well-mic'd acoustic, without a rack of EQ. jj-moon is an acoustic-guitar curve engine in a single AUv3 insert. Four blocks in signal order, each with its own on/off, plus a master strip. SHAPE — A fixed multi-band target aimed at great acoustic recordings: rumble out, body in, boxiness out, soft mid dip, string presence, air on top. Three voices — Steel, Nylon, Flamenco — share the same knobs. One Curve amount for how far you go, Wood for body vs sparkle, Presence for the strings. This is the block the whole plug-in is built around. COMP — An optical compressor with program-dependent release. Soft by design for acoustic dynamics. One Comp knob for threshold, ratio and make-up together, plus Attack and Release. A gain-reduction meter shows what it is doing. WIDTH — Stereo micro-pitch and short delay (the same family of trick as a classic microshifter), with a Focus crossover so the body stays centred while the highs open up. SPACE — A short stereo double with gentle flutter, into a soft acoustic room bloom. Not a spring tank — just a little air around the instrument. FIFTEEN FACTORY PRESETS Default, Fallen Leaf, Fingerstyle, Piezo Soft, Stereo Porch, Close Mic, Moon Room, Strum, Curve Only, Nylon, Concert Hall, Spanish Soft, Flamenco, Rasgueado, Soleá. Save your own from the preset window; swipe left to rename or delete. WORKS WHERE YOU WORK An Audio Unit v3 effect: GarageBand, Logic for iPad, AUM, Cubasis, BeatMaker, and any other AUv3 host. The included app is a working player — six acoustic demo parts are bundled (steel + nylon), or run your own playing through the microphone. The panel is drawn procedurally rather than assembled from bitmaps, so it stays sharp at whatever size your host gives it, on a phone or a 13-inch iPad. Moonlight, Slate, Field Green, or Tweed finishes. FREE TO TRY Seven days free from first launch. No account, no signup, no subscription. After that, one purchase unlocks it permanently on all your devices. If you do not buy it, the editor keeps working and audio passes through dry — nothing you built disappears. jj-moon is an original effect. Preset names point at a feel or a place. It is not affiliated with, endorsed by, or associated with any artist, label, or other plug-in maker, and does not recreate any particular recording.
