G-Storm Electro 101-VCF Eurorack Adaptation Roland SH-101 Filter Demo 01

Today I am proud to show you my 101-VCF - my adaptation of the Roland SH-101 lowpass resonant filter in a slim 8HP Eurorack module. A filter described as somewhere between a Juno and a 303. Every effort has been taken to preseve the original analog circuit as much as possible. Be warned - some harsh resonance squealing ahead! Recorded direct via Mackie mixer to Tascam DR-05, no effects or post-processing.

Oscillators - Pittsburgh Synth Box Square, PWM, Sub
Envelope Contours - 2xADSR dual envelope, Bastl Skis
Sequencing - Arturia Beatstep Pro Pitch CV + gate"


"This is no emulation, this is the 101- VCF: a faithful adaptation of the Roland SH-101 low pass resonant filter circuit in a slim, skiff/boat-friendly, 8HP Eurorack format module. It has that un-mistakable sound not found in any other Eurorack clone.

Great care was taken to keep the 101-VCF fully analog circuit as close to the original as possible including: a rare OTA filter chip, resonance feedback bias, and thermistor frequency stabilization.

The 101-VCF is a little blue beastie that wields two audio IN jacks with a MIX pot. Two CV IN jacks w/ signal attenuation pots allow you to modulate frequency with any two polar/bi-polar signals, low Hz up to audio rates. Every module is hand-assembled and ready to rock your world.

Available exclusively in my Reverb Store"
