Details on the New Knif Audio BBD

You might remember the quick demo of the Knif Audio 5U BBD Delay Demo posted back in September. New details are in:

BBD The analog delay to rule all analog delays

-Stereophonic analog bucket brigade delay with
-precision analog clock generators,
-variable frequency anti-alias and reconstruction filters for wide frequency response and -advanced companders and careful clock signal handling for high signal-to-noise ratio
-Superb-sounding tube distortion stage for the delay path with four NOS SQ pentode tubes
-Six 4096-step BBD ICs for 20ms-600ms (1200ms in mono) delay time
-Seven different operational modes, including X-fed feedback signals
-Versatile LFO
-Tempo divisions
-Tap tempo and external sync
-Beautiful, solid walnut housing and engraved and color-filled panels

Overview

Knif BBD is a stereophonic analog bucket brigade device (BBD) delay. It is a no-compromise device rich in features. What sets it far apart from any other device in the market are the unique self-adapting anti-aliasing and reconstruction filters which provide the widest possible frequency response for any given delay time setting without any aliasing.

The unit features in total six 4096-step BBD ICs which results in maximum delay time of 600 ms for a stereo signal and 1200 ms for a mono source. The device has got seven operational modes for different effects and comes with a wide range of control signal inputs and internal control possibilities. The unit features a microcontroller for relay switching and timing tasks such as tap tempo and time division. However the signal chain and clock generation are fully analog and built using state-of-the-art components.

The other very unique feature to the device is a vacuum tube distortion stage located before BBD circuits. It consists of four NOS Special quality pentodes in total. The amount of distortion is continuously adjustable without affecting the overall signal level. In addition to this, the spectrum of the distortion can be selected.

Ambient Soundscape with Generative Micro-Loops | Reconstructed 2026-01-20 by atnr

video upload by atnr

"This piece was created using the ‪@SequentialLLC‬ Prophet-10 and a self-developed ambient music generation software called Ambient Engine. Cut-up samples are transformed into micro-loops, forming an ambient soundscape layered with synth pads.

The Prophet-10 is played with reverb applied via ‪@strymon‬ blueSky.

Ambient Engine plays samples at both fixed intervals and random timings, processing them through a micro-loop effect, delay, and reverb before output. The samples include field recordings captured in urban areas and parks, as well as sounds from a Rhodes MKII."

Prophet-6 + Minifreak = Vangelis, P.I.

video upload by Good Sunset

"Theme song for Vangelis, P.I. No criminal is safe on the Parisian streets when Vangelis, P.I. is on the case. From the blinding lights of the Champs-Élysées to the rain-slick Montmartre back alleys, this bearded Hellene wants justice, peace, and harmony for the city he calls home—and the CS-80 that’s his only true love.

Tune in Friday night at 8, 7 Central and Mountain.
