AU Studio vs Morphix Synthesizer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
AU Studio
This app acts as a dedicated host for Audio Unit extensions, allowing musicians and developers to inspect, audition, and test installed audio plugins. It provides detailed information about each unit's capabilities and behavior without requiring a full digital audio workstation.
- Scan and catalog installed Audio Units
- Filter plugins by developer, type, and status
- Load AUv3 interfaces or use detailed inspector
- Inspect registry identity, MIDI support, and parameters
- Route CoreMIDI sources and audition audio effects
- Monitor runtime CPU and memory usage
- Built-in manual for guidance

AU Studio is a focused Audio Unit host, not a DAW. Open the plug-ins you already own, hear them in seconds, and see exactly what they expose. Made for musicians, sound designers, and Audio Unit developers who need a fast, honest test bench. No session to build, no tracks to arm. Pick a unit from your catalog and its interface opens in a panel of its own, named and sized to the plug-in, with your host controls in a bar above it. Key features: - Scan the instruments, effects, music effects, generators, and MIDI processors already installed on your device: AUv3 on iPhone, iPad, and Apple Vision Pro, plus AUv2 on Mac. - Filter by developer, type, or search text, and hide Apple built-ins to focus on third-party gear. - Open a plug-in's own interface when it ships one, and fall back to a metadata view when it doesn't, with the full inspector always one tap away. - Inspect identity, four-character codes, version, sandbox and cached validation status, MIDI support, busses, parameters, presets, latency, and tail time. - Step through factory presets, then save your own working state without leaving the interface. - Play instruments from the floating MIDI keyboard: notes, pitch bend, mod wheel, auto, mono or poly voicing, a shiftable range, and one-tap panic for stuck notes. Your hardware controller lights up the on-screen keys as you play. - Run a guitar, a microphone, or any channel of your interface through a loaded effect. Pick the device, pick mono or stereo, pick the channels. - Load a track into the floating media player, scrub the waveform, loop a section, and play along with your live input at the same time. - Check a signal path in seconds with the built-in test tone. - Route external CoreMIDI sources in, and send generated MIDI back out to a CoreMIDI destination. - Test MIDI 2 units with automatic, MIDI 1, or MIDI 2 protocol selection: high-resolution notes, registered and per-note controllers, per-note pitch bend, discovered MIDI-CI Profiles, and a monitor showing raw or decoded MIDI going in and coming out. - Choose your output device on Mac, and set sample rate, buffer size, and which MIDI sources are enabled. - Keep host-process CPU and memory in view while you work. - Open unfamiliar plug-ins with less risk. AU Studio asks first when the system does not mark a unit sandbox-safe, and a peak limiter sits across the host output. - Read the built-in manual, fully searchable: discovery, routing, presets, hardware input, floating tools, troubleshooting, and developer notes. What AU Studio is: A focused host for discovering, opening, auditioning, and inspecting the Audio Units already on your device. It answers the practical questions: Is the unit visible? Does it load? Does it have an interface? What busses, parameters, presets, and MIDI capabilities does it expose? Does MIDI reach it? Does audio pass through it? What AU Studio is not: It is not a DAW. No multitrack recording, clip launching, timeline arrangement, piano-roll sequencing, MIDI learn, automation lanes, song export, or mastering tools. AU Studio ships no Audio Unit of its own — no instrument, no effect, no DSP engine. It hosts the units other apps provide and wraps them in host-owned routing, auditioning, and inspection. Discovery uses the system Audio Unit registry. If a provider app is not installed, not enabled, or not visible to the platform, AU Studio cannot invent it. Interface behavior, presets, parameter meaning, MIDI mapping, and DSP results belong to each Audio Unit.

https://youtu.be/pwx72zQD0p8 Morphix - Morphing Wavetable Synthesizer Morphix is a polyphonic morphing wavetable synth and a faithful reconstruction of the lost 2005 FSR Morphite. Its architecture, parameters, and complete 64-patch factory bank were reverse-engineered from the original and rebuilt from scratch with JUCE — now a modern, multi-platform instrument themed after Aleph Void. A morphing oscillator feeds a state-variable filter, an amp VCA, and a stereo flanger, shaped by independent amplitude and filter ADSRs and a tempo-synced LFO. Sweep the morph parameter for evolving, animated textures — from glassy pads to gritty leads — all wrapped in a clean, dark Aleph Void interface. Features • Morphing wavetable oscillator into a state-variable filter (cutoff / resonance / env / keytrack) • Independent amplitude and filter ADSR envelopes • Tempo-syncable LFO routable to morph and cutoff • Built-in stereo flanger • Full pitch section with bipolar tune / fine • 64 factory presets recovered from the original synth • Import / Export your own .vstpreset patches • Branded Aleph Void UI — void palette, violet accent, JetBrains Mono type • AUv3 plug-in for use in GarageBand, AUM, Logic, and other AUv3 hosts Plays in your favorite DAW or stands alone.
