Haku and Infinite Machinery modules

Tabby cat with two eurorack-module boxes. One os marked M-infinity and TZ Dual VCO.

Haku helps his human pal Erik Ribeiro (@eriksuperlazy on Instagram) unbox and set up new modules from Infinite Machinery. Erik got these back when we were all at Knobcon. I, too, am still setting up some of the modules that I acquired there.

It appears the Infinite Machinery modules in question are the TZ (thru-zero) Dual VCO and Low Road filter.

And here they are installed and set up to make some noise.

Chichiro and Doepfer Dark Energy Mk1

The Doepfer Dark Energy was built around the Curtis CEM3394 “synth on a chip”. Curtis filter chips are well known and prolific in analog synthesizers, but this chip also includes a VCO and VCA – in short, a full synthesizer voice. It would definitely be fun to get hold of one of these, either packaged like the Dark Energy or on its own to experiment with.

Pinki with Analog Systems and more modular

Pinki shows off a cool Analog Systems modular, with not one but two Oberkorn 16-step sequencers. There are several other Eurorack modules from other manufacturers on the lower level, which we shall leave as an exercise to the reader.

Oreo with Gakken SX-150 MkII

Cat with small red synthesizer. The words "Analog Fog" are written on the side.

Oreo returns! This time, he is showing off a Gakken SX-150 MkII synthesizer. Submitted by John Weiner via our Facebook page.

The Gakken SX-150 is a tiny analog synthesizer, sharing some elements with both the Stylophone and Korg Monotron series. It has a solid feature set for such a small instrument, including multiple LFO shapes, independent controls for filter cutoff and resonance, envelopes, and buttons to automatically sweep the filter. Like the stylophone, the stylus is the main pitch control. A purrfectly cat-sized instrument, though the stylus must be a bit challenging for paws.

Feline drone chord and SOMA Lyra-8

I’ve been training my cat to play ambient music. Last night he hit me with this hauntingly beautiful chord change after 10 minutes of A7sus4

A beautiful cat and a beautiful chord. From Jam2go via BlueSky.

The synth to the left of the cat is a SOMA Laboratory Lyra-8. The keyboard is left as an exercise to the reader.
