Synth designer Paula Maddox shared this video demo of the new Dove Audio D501 VCF, which is based on the NJM2069 VCF/VCA chip.
The Korg NJM2069 VCF/VCA chip was used in synths like the Poly800, DW8000 and DSS1. The module features controls for cutoff, resonance, 12/24dB output mode, Filter cutoff CV depth, Resonance CV depth, VCA CV depth and VCA gain.
Here’s what Maddox shared about the technical details:
Here the Q911 drives a Moon Modular quantizer into two WTF oscillaors set to sawtooths, fed into a mixer and into the D501. The Q119 also clocks a quad AD/AR module and the output of the D501 goes into the Corsynth Quad VCA, and also to the FX Capacitor, to create a delay.
Also notable in the video is a custom trigger expander module for the Synthesizers.com Q119, which is used to evolve the sequence length. Maddox plans on publishing the PCB and Bill of Materials for this as a DIY project.
