Kosmodrome fills up

I finally got around to putting a third PSU and bus board in the case and loading up all those modules I made in March and May. That included making a dozen power cables in one sitting, and testing them — the testing took maybe three or four minutes, with the cable tester. They all […]

Audio mixer

A new module today, an audio mixer. Yippee. Yeah, boring, but essential. It’s intended for in-synth mixing of audio signals — not as an output module (that’s another story). This one, like the DC mixer, has three inputs, each with a slide attenuator, a general level control, and two outputs. Unlike the DC mixer it […]

Super sub

A while back Carmelo Azzarello posted a design for a sub oscillator, then later a revised version. He did it on stripboard as an auxiliary device to use with his Behringer Crave, but I decided to draw up a PCB for a synth module version. A sub oscillator is a device that takes an audio […]

The Meg

I’ve done only a bit of circuit bending, so I’m not up on everything that’s otherwise commonplace among benders. Apparently people have been bending toy voice changing megaphones for a couple decades now, or something like that, but I wasn’t aware of it until Soundbender uploaded his video on the LMNC Discourse. From there I […]

Positive thinking

The dac/ino board, which is the heart of the Dual Quantizer, has a significant limitation in that the input CV range is 0–+5V. If you have a bipolar CV source — a Sloth Chaos, for instance — forget it, you can’t quantize it. Or you can, but anything negative gets “quantized” to zero. It’s a […]

Next module: A Kosmo conversion — a konversion — of the Nonlinear Circuits Sloth Chaos. This is a chaotic CV generator. It outputs a CV that varies smoothly and not very rapidly, but doesn’t follow a regular pattern. It usually sort of kind of approximately repeats itself every 15 seconds, but not exactly, and not […]

Finally got the new case together. My woodworking skills are rudimentary at best and it shows, but it does seem to be sturdy and functional enough. Not a moment too soon, either; it’ll be full before long! The panel in the middle is a bunch of passive “jumblers”/multiples and attenuators. The former good for both […]

The switched multiple’s record for largest number of panel components didn’t stand long. This new module has, if I’ve counted correctly, 59 panel components. Then again, it’s a bit bigger than the switched multiple. 20 by 40 cm. It’s an 8 Step Keyboard Sequencer, my variant of the LMNC version. Sam Battle designed a digitally […]

Switched on

LMNC Discourse denizen Cory Torpin sent me boards and panels for three Kosmo modules he’s designed. (Thanks Cory!) Tonight I built one, the Switched Multiple. It’s inspired by the Doepfer A-182 module: Eight jacks connected to eight double pole switches. Jacks whose switches are flipped to the left are (passively) connected, and so are jacks […]
