This is what I've been up to for the past months. RDRPT is a feedback looper, inspired by no-input mixing techniques and harsh noise. It's intense, chaotic and unforgiving. I enjoy it a lot.

How it was designed, schematics etc come out tomorrow on https://gnd.buzz

For now just wanted to share the looks

Hi Merveilles, thanks for having me :)

I enjoy making music and noise, as well as putting together contraptions that help me with that: analog pedals and synths, a little bit of software.

Recently I've been trying to explore atonal and noise elements in music, improve my sound design chops and look for unusual movie soundtracks. Any pointers to artists and instruments in that realm would be appreciated!

Here are some of the records I've had a chance to participate in:

Cultured by Day Dress (post-hardcore / screamo): https://daydress.bandcamp.com/album/cultured

I II III by Dzierzynski Bitz (novy twist) https://open.spotify.com/album/43PZhz9sAdwtaDObFLx1qK?si=BVZpWQP3TJ-7IhGXh7pgKw

Some of the devices I've made:

All Animation crossfader pedal: https://akkusativ.cc/

Hypno delay: https://pedalmarkt.com/pages/delay

A polyrhythmic metronome web app I've made a while back: https://polychops.com

I'd like to do better at documenting what I do. Hence this new account and a video channel here: https://makertube.net/w/s1rLiRFGBmCoNzSgEnNEUx

That's pretty much it. Happy to be here!

I've made *many* little SynthDIY boards over the years, targeting: low-cost, for newbies, Pico & CircuitPython. Here are some.
I've never been quite satisfied w/ the results.
Maybe the solution is more knobs & more choc keyswitches?
Good idea?

Wow this is a great resource if you want to get to know your Yamaha synth chips...

I seem to have access to YM2413, YM3812, YM3420, YM2414, YM2164 and if I can get my RC2014 sound card up and running maybe a YM2149 too :)

For the last month or so I've been working on seeing how far I can push CircuitPython into emulating a TB-303 bass synth. With the new audiofilters library, you can "stack" filters to make two two-pole filters seem like a 4-pole filter, getting close to that squelchy sound we need. My efforts so far:

Progress. Finally to attaching wires to the first pedal.

Getting a test rig together, but if I did an OK job soldering, I should be able to get sound going through.

what do you do when you realize that you immedietly need a line to eurorack level booster? just deadbug it, no time to wait for custom PCBs.

now I'm off to cover this mess upwith a blob of hot glue.

An ESP32-S3 DevKitC prototyping board with MIDI, PWM audio output, potentiometers and its own power circuit.

Nothing makes your instruments break like having a performance tomorrow.

I think a bunch of *jacks* failed? They’ve been resoldered several times. Something might have melted. So now, randomly, there’s no positive side to a bunch of potentiometers until CV is plugged in. And then there is.

So, for the performance, I have to keep those parameters externally controlled.

Adventures in #synthdiy !

Using my USB MIDI to Serial/CV board as a Korg Volca Modular compatible USB MIDI to CV converter.

Note: Please don't do this. Your Volca deserves better than my electronic fumblings! :)

This one is a bit niche... an Arduino Pro Mini USB Host to serial MIDI and CV/GATE.

Probably.

I mean all the individual bits seem to work, but now I need to actually write the code to do it :)

My new video is out where I take a look at the Eurorack Power System, at its different voltages and connector types.

Welcome, @pr1m0rd1alp0uch , to xeno, to Mastodon, to #synthdiy, #modularsynth , and #synth !

You’ll probably want to follow @hissquiet and @jepyang, as well as others whose handles I don’t remember and who I’ll go look up right now!

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 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.

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
