#DevLog: #Anklang #SolidJS Influx

🧬 Fixed some of my #LitElement bugs by migrating to solid
🧩 Refactored & simplified modal dialog creation

🎯 Goal: Robust UI with modern reactivity patterns!

#WebDev #100DaysOfCode

#DevLog: #Anklang: Testing #SolidJS

🚀 Migrated our main UI shell from #Lit to Solid
⚡ Using Signals definitely made dealing with reactivity easier
🧩 This is still a test migration to get a basic feel, but it looks like a significant improvement overall

In #Anklang, we have been running into warnings from #Lit like:

> Element scheduled an update (generally because a property was set) after an update completed, causing a new update to be scheduled.

You should be good unless you see a warning directing you here:
https://lit.dev/docs/components/properties/#when-properties-change

@hmiron

For #Anklang we expect to have lots of small updates at the GUI, but the number of components (Tracks, Clips) remains mostly stable throughput the runtime. We do however have some heavy canvas uses (PianoRoll, Spectrogram).

It wasn't too easy to map these requirements onto Vue2/Vue3, which is why we moved to Lit. However for Lit we also have to bundle a Signals library to implement all needed updates and still see missing updates / complains about too many rerenders at the UI.

Since we need Signals anyway, it makes sense to look into SolidJS as a UI solution as well.

So here is a Wiki page with the result of LLMs comparing the two under our requirements:

🚧 Quirk debugging still ongoing, but progress is solid!

I'm publicly committing to the 100DaysOfCode Challenge, aiming to work on #Anklang and tweet about it daily.

I expect it to be far easier to spend an hour coding every day than to craft an intelligent microblog message about it...

TIL about #Clang --extract-api!

Currently rewriting my C++ ←→ #JavaScript binding generator for #Anklang based on the #JSON output.
Should also be super useful for generating API #Documentation 🤔

Happy to share the release of #Anklang 0.3.0! 🎶

This update brings improved UI & #MIDI handling, bug fixes, and new features like the LiquidSFZ device for #SFZ and #Hydrogen drumkit support. Enjoy enhanced #Freeverb and Blepsynth devices, a new Saturation effect, and CLI improvements. Thanks to contributors @ritschwumm and @swesterfeld for their valuable work.

#AudioSynthesis #NewRelease

*Anklang 0.2.0*

#Anklang is a digital audio synthesis application for live creation and composition of music. It runs on #Linux and is Free Software.

The 0.2.0 release improves audio synthesis capabilities, user interface, documentation, performance, packaging, and testing. We support new CLAP (draft) extensions, non-linear mappings for BlepSynth ADSR times, a Jack PCM driver, context help via F1 key, and improved note editing in the piano roll.

https://github.com/tim-janik/anklang/releases/tag/v0.2.0
https://anklang.testbit.eu/

Wrote a #LockFree (and Obstruction-Free) memory #allocator for use in low-latency real-time threads.

Blocks are 64-byte aligned to avoid false sharing, alloc+free calls of the underlying Bucket- and Bump-Allocators are O(1).

A seperate thread is notified when the Bump-Allocator reaches a watermark. It will then extend the pool of pre-allocated (and pre-faulted) memory, so the Bump-Allocator can continue to serve requests concurrently without syscalls.

#Anklang

Been working on this for a while, now #Anklang finally starts to render parameters for #CLAP plugins. I'll trigger a nightly build soon with CLAP parameter support included.

CLAP - CLever Audio Plug-in API

Last week the CLAP-1.0.0 got tagged and LWN ran an article about it.

Today several projects (and a number high profile companies) announced interest in supporting #CLAP for their #DAW and plugin developments:
https://u-he.com/community/clap/

Last weekend I started to implement CLAP support for #Anklang, the API is farily straight forward and Anklang can already recognize the Beta version plugins listed in the above announcement.

LWN article: https://lwn.net/Articles/893048/

@zrythm
I plan to implement the same thing in #Anklang. And for the record, I'd be happy to see that as an opt-out rather than opt-in. The reason is that most professional software behaves that way these days, which influences user expectations.
Probably a good topic to start a poll for ;-)
