Niviem Bucket AD01

Analog Bucket Brigade Delay

Inspired by the legendary Moog MF-104M Analog Delay (2000-2017). True 4096-stage BBD emulation with SA572 companding, voltage-controlled LFO, and authentic analog character.

What Makes It Special

MN3005 BBD Emulation

True 4096-stage bucket-brigade delay modeling with clock-dependent Butterworth filtering. LONG mode uses dual chips (8192 stages) with authentic 4-filter cascade.

SA572 Companding

Log-domain compressor/expander with 2:1 ratio, 3ms attack, 13.5ms release. Crystal-clear repeats with dramatically reduced noise floor.

Dual Delay Modes

SHORT mode (40-400ms) for bright immediate delays. LONG mode (80-800ms) for warmer, darker textures with extended decay.

6-Waveform LFO

Sine, Triangle, Square, Sample & Hold, Saw, and Ramp waveforms with tempo sync. Create chorus, vibrato, or experimental pitch effects.

TL072 Drive Stage

Modeled input saturation with authentic slew-rate limiting and ADAA tanh function. Up to 16× oversampling for transparent saturation.

Analog Character Options

Companding on/off for clean vs. lo-fi character. Clock bleed for authentic BBD artifacts. Musical self-oscillation at high feedback.
