Billie and waveform experiments

I am experimenting with a 7.83 Hz waveform with a deviation of 0.1618 Hz in stereo and my little cat Billie, intrigued, places herself in the middle of the 2 speakers. I love playing Doctor Frankestein, er, Doctor #sebairstein #maxmsp #7,83hz #cats #waveform #iwanttobelieve #soundmedicine

The adorable Billie disrupts a delicate experiment with 7.83 Hz waveforms separated by 0.1618 Hz (a number connected to the golden ratio). From sebairstein.bsky.social on BlueSky.

Grady with Lost + Found pedal and Les Paul

A captivating jam featuring our pals Grady (the cat) and Doug Llewellyn (@doug_whowever on Instagram). They play a Les Paul guitar through the Lost + Found pedal from Chase Bliss. It has some intriguing effects that harken back to earlier eras of experimental electronic music.

Cat playing microKORG

We see a cat playing a microKORG. As a smaller synthesizer, it can’t quite handle the cat’s weight.

We also see an unusual all-white MS-20 and Moog Sub Phatty among other instruments and gear.

From @landonbalk on Instagram, who adds:

He makes custom patches that get used in every one of my songs.

We will definitely have to check out their music!

Gerty and modular (Shlappi, Behringer, Calsynth)

Gerty poses with a modular system that features modules from Shlappi Engineering, Calsynth, Behringer, and more.

Gerty aKa Gertimus Prime aKa Mr. Beans is all “chuffed” about the An electribe called quest practice sessions…

Gerty is certainly dapper in these photos!

Cat Petting Guide PCB

A “cat petting guide” on a PCB board for a modular synth.

From Jolinlab on Instagram. You can see their various synth offerings on their website.

I’m not sure which one has the cat PCB, but I suspect it’s the new Avalith instrument.
