Multimode Ladder Filter vs MIDIHuman Comp

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.

MIDIHuman Comp is an AUv3 MIDI processor for the chord part — organ, piano, pads, guitar. It makes no sound of its own: your chords go in and come out on their way to your instrument, played the way a comping player would play them — a little different every time round. It never writes new chords for you. It works on top of what you play: variations happen only on the steps you mark, only as often as you set, and always on the chord your loop plays there. HUMANIZE AND GROOVE - A chord lands a little late now and then — the whole chord together, never smeared into a strum — and velocities move - Quantize toward a grid and add swing LEARN - Hears the key — or set it yourself - Remembers the chord on every 16th (up to six notes each), in loops of 1, 2, 4 or 8 bars, and names it - PLAY keeps the learned chords going by themselves; FREEZE keeps them exactly as they are VARY AND FILL - On a chord: an octave on top, the next inversion, a top note that leans and resolves, a staccato chop, a re-strike - Between chords: organ stabs, and chords that arrive early - Eight chord fills — inversion climbs and drops, stabs, triplet stabs, doublings, a drop-out, an anticipation. Tap FILL or set Auto Fill - Swaps: move everything an octave, or spread the voicings from close to open PRESETS - Factory presets: Organ Stabs, Gospel Push, Soft Pads, Funk Chops, Harmony Lines - Your own presets and stored chord loops; host parameters for automation - A searchable User Guide inside the plug-in WITH THE MIDIHUMAN FAMILY Load MIDIHuman Drums, Bass or Lead in the same host session and they find each other: one shared groove, fills that start and hit together, and a FOLLOW fader for each sibling. - One shared key with Bass and Lead; voicings kept above Bass and below Lead - Sends your chords to Bass, so its walks and fills follow your changes - Harmonize: now and then doubles Lead's line a 3rd or 6th below - With Drums: lean on the kick and sit in its pocket Each MIDIHuman app is sold separately and works on its own. REQUIREMENTS - An AUv3 host that loads MIDI processors and provides tempo and transport. Tested in Loopy Pro. - A chord sound after it — an AUv3 instrument, another app or hardware. - Without the host's clock it still humanizes; learning, variations and fills need the clock. - iPad and iPhone.
