KQ MiniSynth 26 vs Multimode Ladder Filter

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.

A 4-pole (24 dB/oct) ladder filter modeled after the topology designed by Robert Moog in 1965. Four cascaded one-pole stages with tanh saturation at input and feedback produce warm analog-style distortion that scales with drive and resonance. Five filter modes (lowpass, highpass, bandpass, notch, and resonant) cover everything from classic subtractive sweeps to sharp self-oscillating leads. Resonance drives the filter to self-oscillation at high values, generating a sine tone at the cutoff frequency. A dry/wet control enables parallel filtering.
