Multimode Ladder Filter vs Gamepad MIDI AUv3

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.

Gamepad MIDI turns your game controller into a MIDI controller for iOS. The sticks, triggers, D-pad and buttons all send MIDI. Map any control to a note or a CC. Then play your synths, drum machines and effects with the controller in your hands. BUTTONS Play notes or send CCs. Hold for momentary, tap to latch, or fire a one-shot trigger. TRIGGERS AND STICKS Sweep a CC smoothly as you press or push. Great for filters, sends and swells. DIALS Turn the D-pad or a stick into a dial that stays where you leave it. Circle a stick to turn it like a knob. Set how fast it turns, and how long it keeps spinning after you let go. EASY TO MAP Press a control on the gamepad to select it. Set its channel, number and mode on screen. A SEND button makes MIDI learn easy. Your mapping is saved with your project. Works with the game controllers iOS supports. Runs as an AUv3 MIDI plugin. No accounts, no tracking, no data collected.
