Read full description

Make any sound move. RasterFX is a playable modular multi-effects processor for iPhone and iPad. Use it standalone with a microphone, an imported audio file or built-in signals β€” or load it as an AUv3 audio effect in AUM, GarageBand, Logic Pro for iPad, Loopy Pro, Cubasis and other Audio Unit hosts. BUILD YOUR EFFECT CHAIN Choose from Filter, Delay, Drive, Reverb, Grain, Repeat, Motion and Dynamics. Arrange up to six plates in series or split them into parallel A/B paths. Reorder the chain and the sound changes with it. MODULATE ANY CONTROL Patch LFOs, envelope followers, random and chaos sources, step sequencers, MIDI, macros, the XY pad or device tilt to any control. Create up to 16 modulation lines, with live arcs showing exactly how the sound is moving. PERFORM THE PATCH Morph between four snapshots on the XY pad. Turn eight macros. Hold four momentary throws for stutter, sweep, reverse and freeze. RasterFX is built to be played with one hand, not programmed and left alone. GENERATE, LOCK, EVOLVE Nudge a patch, reshape it or roll a new one. Lock the parts you want to keep, undo any result and save the seeds worth returning to. Evolve lets the patch drift over time while staying anchored to the sound you chose. SEE WHAT YOU HEAR Every effect has its own live visualizer. The CRT and halftone interface makes filters, delay taps, grains, dynamics and modulation visible without turning the screen into a wall of meters. RECORD THE RESULT Record the processed output to WAV, rename takes and share them from the app. FREE TO START. PRO ONCE. Free includes all eight effects, all modulation sources, every factory preset, three plates, four modulation lines and 60-second recordings. No ads, account, watermark or reduced audio quality. RasterFX Pro is a one-time purchase β€” not a subscription. It unlocks six plates, 16 modulation lines, split routing, XY snapshot morphing, Evolve, A/B compare, unlimited recording length and your own saved presets. Your saved sound always plays back exactly as created, even if it uses Pro features; Free limits editing, never playback. Made for headphones, late at night.

About

J.J.Moon AUv3 Plugin

Features
Read full description

Body, air, and string detail β€” 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 β€” 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 β€” Steel, Nylon, Flamenco β€” 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 β€” 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 β€” 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 β€” A short stereo double with gentle flutter, into a soft acoustic room bloom. Not a spring tank β€” 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, SoleΓ‘. 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 β€” 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 β€” 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.
