i wrote an efficient convolution reverb for dreams while at mm years ago, and found myself in need of one again. my memory was hazy on the details, and i couldnt find it written out in a simple way i could immediately understand, so i chewed a pencil and reminded myself. heres how i think about it

dual wielding

leaning into this text editor/visual editor dual, i've made the code colourer detect comments like /*====*/ and turn them into sliders. I really like how plain old source code remains the 'source of truth' for all state and the editor just doodles over it.

i really appreciate C99's variable length arrays. so you can write float foo[n]; where n is runtime variable! in before the safety crowd: obviously just as unsafe as alloca (ie be careful of n's range) but less error prone as you dont need to compute a byte size by hand. and more readable.

when you have your own text editor, everything starts to look like a .... textnail? behold, I can now edit my LFO shapes with copy and paste...

i love the colour palette of Scavenger's Reign so much. it feels like 1970s pulp comics' colours have been transported onto my tv.

TIL about 'Sturmian words', which incidentally are also (a way to generate) euclidean rhythms en.wikipedia.org/wiki/Sturmia...

writing a recursive descent parser, & just want to vent into the void that i have no muscle memory nor particular aptitude for it; its humbling to have to tackle a simple goal in such noob baby steps. i know if i wrote em more often, itd be done in 15 mins. but good to struggle thru & try to improve

FWIW I have a public domain implementation of band-limited ramp (discontinuous first derivative) to go with band-limited step in my line segment oscillator. Instead of minBlep, it's a symmetric Blep you have to add "in the past" (just delay the whole signal), because ramp didn't seem feasible.

oh i love this font & minimalist font editor brutalita.com

i started to make a live coding environment for myself! its currently basically shadertoy but on my mac with compiled c for the audio. its not a particularly unique wheel, but it's *my* wheel, so I am mostly experimenting with the details to see what makes me feel productive & creative.

@todepond.com when is the next openslots?

nice little bit of randomness: opened instagram to see this post enjoying my 3d printed 1u/3u eurorack adapters, which id uploaded to thingiverse and forgotten about :) www.instagram.com/reel/DOfYhZt...

grain blanc playin' on the plinky+ www.youtube.com/watch?v=XZZl...

Made a nice page for all my demoscene favorites. mrdoob.com/demoscene/

jlc day! while on vacation i speed designed a tiny 'mini pedal' - a rechargeable freeze reverb/glitch effect you can just put inline in a eurorack cable. to my surprise the design mostly worked... so i ordered 20 to take to maschina bristronica. sw? 90% done... ish. wcgw

oh and plinky+ is out! this is a total remake/overhaul of the physical side of plinky by my amazing collaborators makingsoundmachines. bigger, metal, well made. german! :) and meska - one of the OG plinkers - has been making some cool noises. www.youtube.com/watch?v=mAtt...

i found this garten.salat.dev/meta/youre-d... really inspiring. so I decided to make a blog too. it doesn't have any content I haven't already posted here, so nothing to read yet, but the process of writing it is the point. wonder if I'll ever post. prob not, but hope so. plinkysynth.com/alexblog/

i made a quick (silly) 'analog' scope www.shadertoy.com/view/wffBz8

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge? It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

Rec Room was fun, but had to lay off a lot of folks, so I am looking for the next opportunity. If you are looking for a senior graphics coder to solve all your rendering problems on any platform, either remote or in the Seattle area, I'd love to hear from you. Picture is purely for attention.

been a couple years since I wrote a dumb pathtracer-in-a-shader; felt that itch again and decided to brush off the cobwebs by 'covering'/'blatantly ripping off' noby's brilliant 10yo 4k www.youtube.com/watch?v=9r8p...

@todepond.com thanks to you and daniel (@?) for hosting algorhythm! was very inspiring. hope to try my hand at some future event.

this garten.salat.dev (best read in order as a long story) is a really great journey through a creative process evolving various DSLs for pattern music (by the author of strudel). I love the philosophies around staying 'unstuck' in such explorative projects. thanks for the tip @boggo.bsky.social

so did everyone fun and lovely end up here or mastodon or what where are the good people at

i uncharacteristically took a trip down memory lane for this (very geeky, sorry) interview about little big planet 1 - thanks to Ayee and Pear for pestering me until i gave in, and illustrating the edit so thoughtfully! youtu.be/zQTZDnR9AbQ?...

a person called RJ has shown up recently on the plinky discord and added himself to the growing line of people who have really meaningfully contributed to the instrument. he's been beavering away improving the MIDI implementation, & rewrote chunks of the sequencer to be way less... buggy. thanks RJ

love this album - maximedenuc.bandcamp.com/album/nachth... - via @mylarmelodies.bsky.social latest Why we Bleep padcast with @tomwhitwell.bsky.social - in which Maxime plugs crazy max-msp midi patches into... a large organ in Dusseldorf. mesmeric!

i love everything about this youtube channel. musical, funny, informative, unusual, lofi... incredible gold youtube.com/@laurisdiych...

i finished it! had to reprint the case to correct a lack of cable access & a missing lip over the back of the keys but - it all works! 'design for manufacture' is very questionable but hey i know what not to do now :)

happy new year! in between mince pies i decided to make a midi keyboard controller, with a fatar keybed, rp2040, small display and 2 encoders... the project was suggested by my friend zac. this the zacboard was born

my 3 eurorack 1U modules are finally out today at thonk.co.uk! a collab with crey.space . bib - reverb, buzzy - swarm oscillator, blueberry - a sequencer of sorts. you can also buy a 3U face plate and mount them all together if you dont have a 1U row. plinkysynth.com/3uspin.gif

I made a video showing the construction of my volumetric display. It’s like a teardown, but in reverse! youtu.be/pcAEqbYwixU

im thinking of using this account mostly to post dev updates on my new 12" plinkysynth project, because thats my current hobby obsession , but im not sure if anyone here follows me for electronics junk :) sorry if you were hoping for graphics. maybe later :)

today, it came to me as if it were a dream: svg over sysex. I am not even sorry, and I will make it exist. yw

hello world
