what if I made a little visual programming language for my synthesizer 🤔

I figured maybe I'd have a go at porting over my synth pipeline tonight, but I also decided I wanted to rebuild it as a python C++ extension and then my attention span bounced violently off the python packaging documentation, soooo... I made the lines look more arrow-dynamic instead :3
Big progress today! I rewrote a bunch of stuff and now the program has exactly the same functionality as it did yesterday, except that some of it is written in C++ now instead of python 😎

Now the tile objects are C++ classes that python thinks are python classes, instead of just being python classes. This will allow me to rebuild the C++ audio synthesis pipeline to use the tile graph directly instead of my earlier interpreter, and the tile graph will be constructed and manipulated by python.

and I wont have to worry about keeping two separate graph representations in sync, they'll just be the same graph.

The next main things to do are building out an audio subsystem for the program so you can hear the patch, and then there's some important stuff missing from the editor like being able to place new tiles.
One of the things I'm really excited about with the design of the compiler is if you modify a patch while it is running, the oscillators don't reset, so you should be able to make a program while performing it :3

I got the audio hooked up to it and everything seems to work right :3

the screen shot doesn't show off how cool this is, because when you're using this to edit constants in the patch, it'll update their values as you input expressions (so, every time you press equals or input a second operator) and so you can hear the change to the patch as you are doing math

I don't feel like being mad at linux right now, so I'm gonna figure out how to record this another time

I've got this hooked up to my audio convolver (a simple slow morphing fm patch convolved with the sound of a metal water bottle with a little bit of water in it being perturbed) and it sounds mesmerizing. Mym described it as "birds in a pinball machine" :3

I've been listening to it for like an hour and I'm so zoned out now 😎

I made it so you can rearrange the nodes now :)

I added a way to actually place tiles now instead of hard coding them!
finally, after five weeks and change of building a visual programming language from scratch, i can now build a working patch starting from nothing :D

The natural thing to implement next would be save and load, but pygame doesn't provide anything for conjuring the system file io dialogue windows (SDL3 has it, but pygame is SDL2 under the hood iirc). I'll worry about that another time I guess.
I'm probably going to go with an xml format so it's easy to extend. I want it to be easy to make custom controls in other applications eg game engines, so this feels like the obvious choice also I'm one of the five people who likes xml.

i'll probably end up adding envelope generators and midi before i implement save and load since it's not really worth using without those but it really depends on which way the wind is blowing when i next work on this

I'm really excited because all of the hard stuff is done now. I mean none of it was hard to implement or design, it's just that I made a bunch of architectural decisions up front and five weeks later the result is a thing that 1) works, 2) I've managed to keep the complexity of implementation pretty low across the entire program, and 3) all of the missing features and areas I want to improve upon have obvious paths to implementation.

and so further effort put into developing this will have an extremely favorable ration of time spent actually making the program more useful vs wallowing in tech debt

I made a short sequence of boops entirely out of oscillators and arithmetic. There's no sequencer or envelope generator. #mollytime

and this is the patch, or at least here is most of the patch. it probably looks complicated but I did not put a lot of thought into it

from my experimentation so far since I got all this working end-to-end, I think modality worked as useful convenience for standing up a visual programming language quickly, but it adds too much friction to this one. In particular when making patches I want to be able to alternate between placing/moving stuff around and connecting stuff, so those two modes need to be merged for sure.

> A cosa serve il Sí al referendum sulla magistratura ? A “toglierla di mezzo”. Interpretazione autentica fornita dalla capa di gabinetto di Carlo Nordio, che ha scritto la riforma. Togliendo di mezzo i giudici, si tolgono di mezzo anche le regole, cui pure il governo deve sottostare. Stiamo sereni?

@arisunz I would love to see a Gleam version of OCapN btw :)

@arisunz Do you mean the protocol Goblins uses (OCapN) or the paradigms Goblins covers?
For the protocol, see https://ocapn.org/ which has an implementation guide here https://github.com/ocapn/ocapn/blob/main/implementation-guide/Implementation%20Guide.md
For the programming environment, there is a heck of a lot in there to unpack. If you wanted to look at it, Goblins' Guile implementation contains a pre-goblins directory which sort of walks through the steps for building up a bare minimum version of Goblins' concepts, though the working version today has much more than that.

Leadership change announced at Bluesky.
I think Jay Graeber's biggest accomplishment: she allowed the Bluesky engineering team to follow their hearts on what they saw as pursuing the best design. Not easy to do given all the other pressures in the role.
Best of luck with what's next, and I hope future leadership does the same.

I fratelli Safdie hanno girato film di indubbio successo. Poi si sono divisi e Josh ha realizzato quest'opera che è candidata a tutti i premi del mondo https://mastodon.uno/@fucinafibonacci/116000144866869734. A me non è piaciuta. Mille volte meglio "The Smashing Machine" di Benny. Ma credo di essere influenzato da un immagine di uomo che, solo generazionalmente, mi vede più vicino a #DwaineJohnson. E dalla presenza di #EmilyBlunt. Dannazione e redenzione di Mark Kerr https://ultimouomo.com/mark-kerr-chi-e-fighter-mma-protagonista-the-smashing-machine
