Do you remember the single most iconic phaser you've ever heard? For the first time, there's a good chance of finding that exact sound captured in a plugin. FEATURES: • Faithful reproduction of a legendary 4-stage phaser pedal from the late 70's - early 80's • Complex effects can be built using composite LFO's, parallel phaser structures, as well as an independent modulation system for the sweep range • Barberpole or "Shepard" phaser included: infinitely rising / falling modulation that can optionally be combined with sweep range modulation • Strong, rhythmic / syncopated patterns can be created by configuring different LFO frequency ratios within the various modulation sources • Mid-Side modes allow adding special phasing effects to stereo sounds • Exact visualization of the notch filters' real-time frequency response, with different stereo options • Exceptional multirate performance: results are less sampling rate-dependent than what's currently available with most digital phasers (even from major manufacturers) • Designed to be an anthology app extensible with additional hardware-based or synthetic analog models in future MIDI NOTE EVENT RECEPTION: RealPhase can accept MIDI note messages, syncing an envelope-based modulation source to note on and off events. This makes it easy to use RealPhase as a powerful analog modeling OTA-based resonant notch filter with any synth or sampler. PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin • Supported sampling rates: 44.1, 48, 96 kHz

Memory MIDI turns your iPhone into a MIDI controller for Ableton Live — and your Apple Watch into a knob. Play and control your set straight from your phone: drum pads, faders, sliders, an XY pad and transport buttons under your fingers, while MIDI flies to your Mac over Wi-Fi, USB or Bluetooth. No audio interface, no firmware, no extra hardware. The app uses standard Apple MIDI built into macOS. WHAT'S INSIDE • Multi-touch drum pads — hit several notes at once, just like a real controller • Faders and sliders for volume, sends, or any parameter you map with Cmd+M • XY pad to control two parameters at once • Mixer, Performance and Buttons screens for live control • Transport: Play, Stop, Record and locators, plus a lyrics notepad • Apple Watch: the Digital Crown becomes a MIDI knob — several knobs, each with its own CC, color and range • Built-in presets plus a custom layout builder: add controls, assign MIDI numbers, rename, save • Control values survive an app restart • Automatic reconnect and a Panic (Note Off) for stuck notes THREE WAYS TO CONNECT • Wi-Fi — Apple Network MIDI (RTP-MIDI), no cables • USB cable — enable iPhone in Audio MIDI Setup on your Mac • Bluetooth MIDI — no Wi-Fi needed Step-by-step instructions for each are right on the Connection screen. QUICK START OVER WI-FI 1. On your Mac open Audio MIDI Setup → MIDI Network Setup 2. Create a session, enable it and connect your iPhone 3. In Ableton Live: Settings → Link, Tempo & MIDI — turn on Track and Remote for the network input 4. Map controls with Cmd+M — and play Memory MIDI is built to be a simple, honest tool for live performance and production: minimal setup, maximum control. This app is supported by ads. Requires an iPhone on iOS 26 and a Mac with a DAW. The Apple Watch knob requires watchOS 26.

Verdict
The clearest difference is price: Memory MIDI at Free against RealPhase's $14.99. Memory MIDI also leads on update cadence (every 2 days vs every 14 months). RealPhase's advantage is ads (none vs shown) and device support (4 vs 2). On in-app purchases there is nothing between them.
