The Delta VCF is a faithful clone of the Korg Delta
synthesizer filter in Eurorack. The lowpass circuit was also found in the
Poly-61. And uses the same OTA chips and
dual transistor as the original Delta.
It is all analog, no DSP, so it will warm up any signal run through it.
Version 2 is the same circuit,
sound and features as version 1. New
features for version 2!
- Revised panel design,
adjustment pots are available from the front
- Module depth is now skiff- and
boat-friendly
- Slightly less current draw
FEATURES
Two selectable filter slopes:
original 4-pole, and 2-pole.
Two selectable filter modes:
lowpass or bandpass.
Illuminated Frequency and
Resonance Bourns Slider pots.
Mix together two different input
oscillators at the input jacks w/ signal attenuation/gain pots. These inputs can overdrive the filter.
Modulate the filter cutoff with
two different input control voltages w/ signal attenuation pots.
There are trim pots on PCB for
adjusting frequency and resonance range.
Some of you out there may want to give a little boost to the resonance
trimpot on the PCB. Doing so will make
this thing scream and howl a little harder.
Please note my modules are
painstakingly hand-crafted in the USA. The face plate waterjet cut, but
the graphics may have minor visual imperfections that are characteristic of a
home-brew project and not a mainstream commercial manufacturer.

Eurorack ribbon connector
