MIDI Magnet — hands-on control for your MIDI hardware. Stop digging through tiny screens and cryptic menus. MIDI Magnet turns your iPhone or iPad into a control surface for your synths, drum machines, and effects units — every CC parameter laid out as a knob you can actually touch. EVERY PARAMETER AT YOUR FINGERTIPS Pick your device from a growing library of brands and models, and MIDI Magnet instantly maps its CC parameters to a clean, touch-friendly layout. Tweak filters, envelopes, LFOs, and effects in real time — values are sent to your hardware the moment you move a knob. CONNECT YOUR WAY Works over Bluetooth MIDI for fully wireless control, or plug in over USB. Connect your device and you're good to go — no drivers, no setup headaches. SAVE AND RECALL PRESETS Dial in a sound you love? Save it as a preset and recall it anytime — all parameter values and the MIDI channel are restored and sent to your hardware with a tap. Sign in to sync your presets to the cloud and keep them safe across all your devices. MAKE IT YOURS Reorder parameters with drag and drop to match your workflow • Organize controls into custom groups with their own colors • Switch any parameter between knob and button control • Edit parameter names, ranges, and CC numbers • Light and dark themes TOOLS FOR SOUND DESIGN Randomize all parameters for instant inspiration — lock the ones you want to keep • Reset to defaults with one tap • Send Program Change messages to switch patches on your hardware • Send all current values at once to bring your hardware in sync YOUR GEAR NOT LISTED? Create a custom device with your own parameter mappings — perfect for rare gear, DIY synths, or anything with a MIDI spec sheet.

FAC Gravity AUv3 Plugin is a frequency shifter for creating Barberpole and Shepard style glissandos, spectral illusions, stereo rotation, chorusing, phasing, evolving echoes, infinite cosmic spaces, and all the combinations you’ll make. The plugin gives you two ways to process the audio source. In Stereo mode, each channel is shifted independently, with a Ratio control determining how closely their frequency shifts align. In Mono mode, FAC Gravity extends the internal quadrature processing to create a wide stereo image from the mono source. The frequency shift can move up or down, from subtle to more extreme spectral transformations. You can set the amount in Hz for classic Bode-style frequency shifting, make it follow your host tempo for rhythmic patterns, or even control it from MIDI notes for a more hands-on approach. A new dimension appears when you let the shifter feed back into itself with Spiral, a customizable loop with delay, blur, filtering, and different characters that shape how the sound circles, smears, interacts, and evolves over time. The result can range from bubbling textures to infinite sustained tones and noisy analog self-oscillation. Each character takes the feedback somewhere different. To dive deeper into new sonic dimensions, FAC Gravity comes with its own modulation module. The LFO, envelope follower, and flexible modulation matrix let you animate most parameters, from subtle evolving movements to complex, rhythmically reactive changes. You can even make the stereo field animate and rotate continuously by making the Width, Phase, and Pan parameters spin! You can shape the effect further by blending the processed signal with the original, while the optional limiter keeps the most extreme combinations in check. • Barberpole glissandos, spectral illusions, rotating stereo, evolving echoes • Dual Frequency Shifting, or Mono Shifting with Quadrature Stereo Widening • Organic Spiral Loop, from gentle feedback to pure analog self-oscillation • Integrated delay, diffusion blur, and independent low/high filtering • Modulation matrix, multi-source envelope follower • LFO with classic waveforms and random spline • Spinning modulation to rotate and animate the stereo field • Tempo-synced or MIDI-driven Frequency Shift, LFO, and Delay • Dry/Wet mix, optional limiting, and goniometer visualization • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro The documentation is available at fredantoncorvest.com/FAC_Gravity.html This is an AUv3 Effect and requires a compatible host to work The in-app purchases are for tipping only, the app is fully functional without them

Verdict

The call

The clearest difference is price: MIDI Magnet at Free against FAC Gravity's $9.99. MIDI Magnet also leads on in-app purchases (none vs 3) and iOS requirement (14.0 vs 17.0). FAC Gravity's advantage is ratings volume (6 vs 1). On rating, ads and device support there is nothing between them.
