'Filter on Filter' Jam: Ladder into Fixed Filter Bank 914 & Lunar Module 'Bit-crushing' Drum Sounds

video upload by AJH Synth Official

"Minimal Synth & Percussion Jam: 3 VCO's into Ladder Filter, then Fixed Filter Bank 914, with DH-ADSR envelope control over mix of both filters. Also down-sampling/bit-reduction effect using the Lunar Module to crunch then distort incoming audio/drum pattern from an iOS app (Patterning 1).

The classic Moog Modular-based Fixed Filter Bank 914 totally transforms the sonic character of the output from the Minimoog-based 24dB low pass VCF, creating a vocal/choir timbre, which is fed 3 sawtooth waves, each with their own LFO/modulation. The envelope automates the FFB module's built-in mixer, morphing the sound from just the Ladder VCF, to the Ladder through the Fixed Filter Bank. The Lunar Module is great for taking a too-hi-fi sound and giving it some lo-fi character, with optional crunchy distortion, making it sit more comfortably alongside it's analogue Eurorack neighbours. Old-school, vintage-voiced sounds and circuitry FTW.

The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself.
