About

Gravity & Wind

Features
Read full description

Gravity & Wind is a physics-driven generative MIDI sequencer and performance controller for iPhone and iPad. Build evolving sequences with Timed generation, hold an exact population with Fixed mode, or tap the field to perform directly. Shape gravity, directional dual-noise wind, bounce, and velocity response, then turn floor impacts into quantized MIDI notes. Free features include five scales (Major, Natural Minor, Major Pentatonic, Minor Pentatonic and Chromatic), 12 factory scenes, motion control, all generation modes, basic CoreMIDI Note/Velocity output, output channels, Bluetooth MIDI, manual sustain-pedal forwarding and up to five user scenes. Presets play with their saved scales, MIDI/Auto pitch, CC and sustain settings even in the free version. You can turn advanced settings off, edit basic parameters, and save within the five-scene limit. Enabling or changing advanced modes requires Pro; reloading a preset restores its settings. MIDI Learn/mappings and MIDI ball triggers remain Pro features. A single, permanent Pro in-app purchase unlocks choosing all 24 scales, enabling and editing advanced preset modes, and the MIDI Processor AUv3 with host sync, automation and project recall; MIDI chord pitch control and Channel 2 ball triggers; MIDI Learn; scene-energy CC 1, Wind CC 2, Direction CC 3; Held and chord-aware Automatic Sustain; and unlimited user scenes shared with the AU. No subscription. Eligible customers who purchased the app before the switch receive Pro automatically. Gravity & Wind has no built-in sound source. Route its MIDI to a software instrument, hardware synthesizer, or DAW. No separate account registration, advertising, or third-party analytics. Purchases and restoration use your Apple Account through the App Store.

About

J.J.Midnight AUv3 Plugin

Read full description

An electric guitar effect for the laid-back sound: squashed until nothing jumps out. Just past clean. Wobbling a little. One repeat behind. That sound is not one pedal โ€” it is a whole vintage clean chain, and jj-midnight is all of it in a single AUv3 insert. Four blocks in signal order, each with its own on/off switch, plus a master strip. COMP โ€” An optical compressor with program-dependent release, the way a real opto box behaves: one knob for threshold, ratio and make-up together, so it squashes without asking you to think about it. A gain-reduction meter reads out what it is doing. This is the block the whole plug-in is built around. DRIVE โ€” Asymmetric soft clipping voiced for second harmonic rather than fizz, a tone rolloff, and a 1x12 cabinet with a movable mic position. Low gain on purpose. It goes from clean with weight to the edge of breakup and stops there. WOBBLE โ€” Amp-style amplitude tremolo with an LFO that morphs from a sine sway to a hard chop, free-running or synced to your host's tempo. SPACE โ€” One slapback repeat with no feedback, into a spring tank with dispersion allpasses for the chirp a real tank makes. THIRTEEN FACTORY PRESETS Default, Laid Back, Escondido, Porch Light, Whisper Trem, Magnolia, Breeze, Midnight, Sensitive Kind, Faded, Cassette, Night Drive, Flat & Even. 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, so you can hear the plug-in on a real guitar part before you open a DAW at all โ€” two dry recordings are bundled, or run your own playing in 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. 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 โ€” nothing you built disappears. jj-midnight 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.
