KQ MiniSynth is a powerful polyphonic modular synthesizer app for iPhone, iPad, and macOS (Apple Silicon).
Design your own custom synth patches by connecting modules in a flexible, visual environment. You can mix up to 100 modules in a patch (limited by device performance).

Features
- Zoomable patch editor: easily connect modules via tap & drag with zoom support
- 70+ built-in preset patches to explore and customize
- External & virtual MIDI support
- MIDI over Bluetooth LE (as central)
- Ableton Link integration for tempo sync across apps and devices
- Audio Unit Extension (AUv3) support, usable as plugin in host apps

Why KQ MiniSynth?
- Enjoy deep modular synthesis in your pocket
- Great for both experimental sound design and live performance
- Educational tool: learn module topology & signal flow
- Efficient implementation aimed at low latency and stable performance

Tips & Notes
- If output is too quiet, check Expression (Ctrl #11) or use “Reset” on I/O panel.
- When using as an Audio Unit, if velocity seems ignored, disable “Ignore Velocities” in settings.
- Performance depends on device — reduce polyphony or number of modules if audio drops occur.
