Mobile MIDI vs FeedbackGuard

Turn your iPhone or iPad into a wireless MIDI controller. Almost any sensor in your phone can be a knob. Touch: • Drum pads, keyboard, XY, faders, build-your-own layouts Motion: • Accelerometer + gyro (6 axes) • Gravity, attitude (pitch/roll/yaw), user acceleration • Compass heading, magnetic field • Barometric pressure • Step cadence, shake triggers Device & environment: • Battery level, charging state, thermal state • Screen brightness • Microphone loudness (analyzed on-device, never recorded) Tracking: • ARKit face blendshapes — 52 expressions • Hand gestures via Vision • AirPods head tracking — nod, tilt, turn Output: Bluetooth LE, USB, or Wi-Fi (Network MIDI) to any DAW. Save and share presets. Built for musicians, producers, and experimentalists. No extra hardware. No subscription. Pay once. TOUCH • 16-pad drum grid with MPE polyphonic pressure • Keyboard with configurable range and octave, MPE-capable • XY pad for two-dimensional continuous control • 8-fader CC bank • Custom layout designer — drag-and-drop your own surfaces MOVE • 6-axis device motion — accelerometer and gyro • Tilt, shake, gravity (X, Y, Z) • Compass heading • Barometric pressure • Per-axis smoothing, deadzone, and scaling EXPRESS • ARKit face tracking — 52 facial blendshapes as continuous CCs • Hand tracking — gesture-based control via the front camera • AirPods head tracking — hands-free expression for live performance SENSE • Battery level and charging state • Screen brightness • Thermal state • Any system signal can drive MIDI MUSICAL TOOLKIT • 27 scales, 31 chords • Chord, strum, trigger, and toggle modes • Intelligent note-off handling — no stuck notes • MPE channel allocation with LRU across channels 2–16 PRESETS • Save, load, import, export • Five built-in templates to get started fast • Share presets with other Mobile MIDI users CONNECTIVITY • Bluetooth MIDI (BLE) • USB MIDI (via adapter) • Wi-Fi / Network MIDI • Auto-reconnect and device picker DESIGNED FOR PERFORMANCE • Low-latency native audio path • Wakelock keeps the screen on during gigs • MIDI activity indicator • Clean, minimalist interface built for low-light stages Every control source is mappable to any CC, note, or pitch bend, on any channel.

FeedbackGuard is an Audio Unit v3 effect that stops acoustic feedback before it ruins your performance. Whether you are singing live, speaking on stage, or recording vocals on iPad, FeedbackGuard listens for runaway howling and automatically places precise notch filters — so you can focus on the show, not the squeal. HOW IT WORKS FeedbackGuard uses PNPR (Peak-to-Neighbourhood Power Ratio) analysis combined with a growth check to tell real feedback apart from normal voice, speech, or room tone. When a howling peak starts to build, the plugin tracks it with parabolic peak detection and deploys an adaptive notch bank that reacts in milliseconds. Designed for live use: attack and release times, suppression depth, and notch count are all under your control. KEY FEATURES • Real-time howling detection (PNPR + run-up check) • Adaptive notch bank — up to 24 simultaneous notches • Live spectrum display with active notch markers • "Balanced" preset for safe, transparent defaults • 3 user preset slots — tap to recall, hold to save • Fine-tuned controls: Sensitivity, Notch Threshold, Suppression, Q, Attack, Release • Optional harmonic tracking for stubborn feedback tones • Optional spectral noise reduction for quiet passages • Full bypass GET STARTED IN SECONDS 1. Open your AUv3 host (GarageBand, AUM, Cubasis, and more) 2. Insert FeedbackGuard as an audio effect on your vocal or monitor channel 3. Tap "Balanced" for recommended live settings 4. Raise Notch Threshold if notches appear on voice or room tone IDEAL FOR • Live vocals and speech • Rehearsals, worship, small PA setups • Mobile recording rigs on iPhone and iPad • Any situation where monitor feedback is a risk COMPATIBILITY • Audio Unit v3 (aufx) effect • iPhone and iPad • Works in any AUv3-compatible host • Mono or stereo, sample rates from 8 kHz to 192 kHz FeedbackGuard — Adaptive Feedback Suppressor by Norwin Palme.
