Rainbow vomit mode for the #eurorack established. That's the starting point I needed.
WS2812B LEDs controlled by FastLED on a Arduino Nano Every, external power supply. Needed a galvanic isolated USB connector to be safe, otherwise I'd have to disconnect the external 3.5A power supply for the LEDs everytime I upload a new sketch. The Nanos should have a diode to protect against this...but better safe than sorry.
Next on the roadmap are multiple lighting modes plus a CV-based colour changing scheme for ambient sets (note values influence colour). Another input for a transistor trigger input (I'm using CV for now). And the menu...will still take some time.

Kind of replicating the experience of a vintage #arp #2600 #modular #synth with a sequencer.
Using a mixer case to house the stack of #behringer 2600 semi modular #eurorack clone along with a series of 2500 clone modules, including a sequencer, a sequencer switcher, a mixer sequencer, a multimode resonant filter, a VCA etc
The Black Centipede #modularsynth in its current form.
On the left is the Rad Dog Eurorack case, for generating signal and taking outside mic input.
On the right is the Voice Nodulator grain mangler/pitchcompressor, for examining sounds closely.
At the top is a repurposed and hacked computer power supply that feeds all segments power via those big chonky, coiled cables.
I just released my first #eurorack module called #theNSAselector it listens into ethernet and makes it audible.

I think this is the first time I’ve really gotten a #eurorack together as a coherent instrument.
Rad Dog, which is built in a thrift store cassette caddy, is composed of these modules:
Top, L-R:
> Kastle digital rungler for barely-controllable audio frequencies
> Vortex Generator for barely-controllable envelopes/low frequencies
Bottom:
> Mic preamp for IRL signals
> Ring modulator to put them in relationship with generated audio
> Passive mult to keep tidy
> Gliss for hand-drawn waveforms.

I have an antiproblem where this grain mangler I’ve built, the Voice Nodulator, solves all of my experimental music problems.
It takes crowded, too-fast, high, flat sounds, then stretches them out until you can hear structure, harmonics, & stereo spread.
I’ll be playing it and a little #eurorack of chaos called Rad Dog along with featured artist @hissquiet
around 7-10 on Sunday May 25 at The Quarters with the Western Mass Electronic Music scene.
Seems I'll have rythmic lighting in my #eurorack case soon :>
...after I write all those damn algos to visualize it beautifully AND do all the menu work for the rotenc :(
But the CV detection works...next time I'll use a transistor.

Voltage divider seems to work, sinus is a bit wonky (used a VCO in CV mode), but I'm only using this for detecting trigger voltages, so it should be fine...

OK, much better. Now I need to order some shorter M2.5 screws and it will be perfect. The only less nice thing is that the encoder is not high enough to be able to screw it to the panel. I should buy a taller model for future units. It's not a big deal though. #eurorack #synthdiy #electronics #3dprinting
Did a video and DIY build on the Jolin Rosa - really nice ability to morph through modulations. https://youtu.be/KJoRqDPGpNc #eurorack

Not too bad, only a couple of sizing mistakes. Almost there. #eurorack #synthdiy #electronics

On the same note, the new #Doepfer #ribbon #controller A-198-2 now sends out also #MIDI. How cool is that. It's great to see #eurorack manufacturers embracing more MIDI. This is how everybody is winning. CV and gate for modular instruments and MIDI for everything else in the studio.

CatSynth · Cheetah, Error Instruments Brinta, Winterbloom Castor & Pollux - CatSynthCheetah looks very content in his snug hiding spot behind the Error Instrument Brinta and Winterbloom Caster & Pollux eurorack modules. We also see an Intellijel µAtt and a Cwejman QMMF. From our friend Kim Cash (@iamshadowdancer on Instagram)
