Announcing the Pro VCF Eurorack Module

Coming next week: the Pro VCF.
The Pro VCF is a faithful adaptation of a well-known 4-pole synthesizer filter in Eurorack.
The core of this design lies an Alfa AS3320 filter chip based on the original Curtis. Countless synthesizers used the 3320: Sequential Pro One, Prophet 5 rev 3, Drumtraks, Crumar Trilogy, Stratus, Elka Synthex, some Fairlight CMI, Linndrum, Oberheim OB-8, OB-Xa, PPG Wave 2
At full resonance the Pro VCF can self-oscillate.

FEATURES
Two selectable filter slopes: original 24 db/oct, and 12 db/oct.
Two voltage controlled input jacks for frequency CUTOFF w/ signal attenuators.
A voltage controlled input jack for RESONANCE w/ a signal attenuator.
Two signal input jacks w/ individual attenuators. At full clockwise, these inputs can overdrive the filter from most eurorack oscillators and audio sources.

My DC571 Lo-Fi Dual Compressor Has Returned

Bringing this one back out of retirement.
Currently available in my Reverb Store.

There's nothing like an Analog Compressor to warm up your sound.
Make percussion grooves a little punchier, bass a bit snappier, and glue the mix together.
My DC571 module has TWO fully independent channels of no-nonsense audio compression made especially to give your Eurorack some of that subltle swingin' groove.
You can even cascade channel 1 output into channel 2 for even more compression.
The DC571 uses an 80s design dual compander chip (still in production) to work its mojo.
Each channel has controls for input level attenuation, output make-up gain, and a true bypass switch.
The DC571 is hand-crafted in USA in limited quantities.
