Niviem Filter S/H
Vintage Filter Sample/Hold + Mu-Tron Envelope
Component-level recreation of the 1974 Maestro FSH-1 / Oberheim VCF-200 sample/hold pedal — three modes (Filter, Sample/Hold, Envelope), five filter types, Leslie 122 cabinet stage, host tempo sync.
What Makes It Special
Three Authentic Modes
Filter (continuous LFO sweep — classic auto-wah), Sample/Hold (avalanche-noise stepped voltages — iconic computer bleeps), and Envelope (Mu-Tron III-style auto-wah driven by input dynamics, a Niviem addition).
Mu-Tron III Envelope Follower
Faithful Sensitivity 1×–12× (the Mu-Tron 'Drive' control) + Attack 0.5–50 ms continuous knob drive a peak-detector envelope. Speed becomes the release-time control in Envelope mode.
Five Filter Types
LP (authentic), BP (vocal/nasal), HP (thin/subtle), Notch (phaser-like), and Peak (EQ-like boost) outputs from the SVF — the original had LP only.
Five LFO Waveforms
Triangle (authentic), Sine, Square, Sawtooth and Random in Filter mode. The original triangle wave is preserved; the rest are modern extensions.
Leslie 122 Cabinet Stage
Authentic Leslie 122 rotating-speaker cabinet modelled from scratch. Switchable, fully bypassable, lifts the filter voice into territory the original pedal never reached.
State Variable Filter
True 12 dB/oct TPT (Topology-Preserving Transform) state variable filter. Musical, non-self-oscillating resonance, correct behaviour at all frequencies.
OTA-Style Saturation
Soft saturation modelling vintage operational transconductance amplifiers. Adds warmth with frequency-dependent Q reduction; the OTA's own tanh non-linearity shapes the envelope follower.
Tempo Sync
Lock LFO rate to host tempo with note divisions from 4 bars to 1/16 notes for rhythmic, locked filter patterns. Speed knob greys out + a sync glyph appears on the value readout.
41 Factory Presets + Six Categories
Filter (13), Sample/Hold (6), Envelope (8), Tempo Sync (4), Cabinet (6), Smooth Tone (4) — calibrated for level consistency (≤ 3 dB peak-to-peak at -12 dBFS). Full user save / load / rename system.
Premium Brushed-Metal UI + Nivipedia
Photoreal milled-aluminium knobs on a brushed-metal chassis, real-time envelope LED, value readouts on every drag, full keyboard navigation. Right-click any control for Reset to Default or 'What is this?' → opens the in-plugin Nivipedia entry.
