Multimode Ladder Filter vs P252 MDN Diode

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.

P252 MDN Diode is a germanium diode bridge compressor created by Pulsar Modular and Marc Daniel Nelson. Nearly two years in the making, it delivers the weight, movement and harmonic character of the rare germanium diode-bridge design - now on your iPhone and iPad. Use it as an AUv3 plug-in in your favorite host (Logic Pro, GarageBand, AUM, Cubasis and more) or as a standalone app processing live sound from your microphone. KEY FEATURES: - Germanium diode bridge compression with program-dependent behavior - RESPONSE TIME and RELEASE controls tuned for musical timing - Ratios from gentle 2:1 up to Limit, plus Linear mode - FF / FB sidechain topology switch - External sidechain input (AUv3) - STOCK / DRIVE transformer voicings and NORM / HEFT weight modes - AIR switch and 3-way analog noise floor - MATCH gain matching for honest A/B decisions - A/B compare with copy, MOD and oversampling - Simpson-style VU metering (RMS in/out) plus dual gain reduction meters - Touch-friendly "Link Threshold & Trim Out" and "Link Trim In & Out" gain staging - Full preset manager with folders, favorites, import and export - Parameter automation in AUv3 hosts Audio is processed entirely on your device - no account, no data collection, no internet connection required.
