"The Loop/Env is a Voltage controllable and very flexible ADSR module. It’s based around the Electric Druid LoopEnv1 PIC, which is a digital clone of CEM 3312 / SSM 2056. It offers CV Control over the envelopes complete time, Positive, Negative and Bi-Polar Outputs.

The module is switchable between Linear and Exponential curves and can either be used as a traditional ADSR or in LOOP mode can function like an LFO (the different outputs come in very handy here especially the +/-). it can also go well up into the audio range in this mode. The Envelope is “snappier than a piranha jacuzzi” minimum envelope times of 1MS through to long envelope times and everything in between.

Features

Attack, Decay, Sustain, and Release Controls
ADSR/Loop Mode Switch
Audio rates possible in loop mode
Large range of envelope times"

Frequency Central Electro Cardiogram VCF VCA Eurorack Module Red Acrylic

"The ECG is a diode ladder filter and uses 6 x red LEDs for the diodes. Diode ladder filters have a different sound to transistor ladder filters. If you’re gonna use diodes, why not use LEDs and get a free light show too? The LEDs will brighten as you turn up the cutoff of the filter, or when a CV is applied.

For maximum visual effect ECG is mounted on a translucsuent red acrylic panel. ECG is based on my Vogue VCF/VCA, the inspirations for the changes to diode ladder the Roland TB303 filter.

Features

Diode Ladder Filter
Indicator LEDs
Trasnlucent Red Acrylic Panel"

"Continuum looks and acts rather like a VCF, in fact that’s exactly what a phaser is, an all-pass VCF. There’s far more to phasers than just sweeps up and down from an LFO, so Continuum has two CV inputs, so you can use a variety of CV sources simultaneously.

The topology of Continuum is 4 swept OTA all-pass filter stages with a fixed all-pass filter stage either side of the swept core. There’s a switch to select Regen over odd or even stages. Most phasers stick to odd stages, but there are undiscovered sonic possibilities using even stages of Regem.

Features

2 Audio Inputs
Odd/Even Stages Switch
2 CV Inputs w/ Attenuators
Freq/Res Controls"

"Great rationalist version of Peters Rolz5.

Meng Qi's circuit layout is art unto itself.

Many mods can be done easily. Separate outs, different values for gongs and filters, ect.

Uses a LOT of bananas to patch. No cables included. Can use alligator clips, or touch.

Cool, weird, not for the faint of heart.

Auction for unit and PS only."

via the listing: "It was indeed purchased by me, last year, directly from Rob Hordijk. This is the latest version of this device (as far as I'm aware), and has the photoelectric eye as is present on all of the newer units. Too, Rob now produces both the 'classic' version (with 1/4" jacks) and a version with a combination of banana jacks and 1/4" jacks. My unit (as can be seen in the photos) is the former, having only 1/4" jacks for all ins and outs. I never got 'round to using this unit, and purchased it solely for the uniqueness and exclusivity. There aren't too many around, and Rob only does small runs when enough orders are received to make it worthwhile. As far as I know, he does still produce the Blippoos, though there's typically an indefinite wait-period between runs. So said, this unit is as new, and in the exact condition as it was when received by me - no known issues whatsoever..."
