For anyone interested, the main author (if I understood properly) did a presentation at RustNL on the UI aspect that was quite impressive performance wise : https://youtu.be/rC4FCS-oMpg

Technically, that talk is by the author of the UI system/IDE that uses the synthesizer as an extended hello world. The synthesizer itself is by a different guy ( https://thisisnotrocketscience.nl ) who's been calling his bassline synths somethingmetallicfish since almost forever.

The RustNL presentation is a nice up to date view of where we are with makepad.

Very impressive UI work with Rust. As @rvdca pointed out the author had a great presentation. Definitely recommend it.

I notice that there is a bug when I open the console with cmd-option-J: a note will be triggered and stay there forever.

The audio worklet uses postMessages (https://makepad.nl/makepad/platform/src/os/web_browser/audio...), which is not GC free.

For those are interested, I am maintaining https://glicol.org/ which is also an Rust/WASM audio app in browsers.

The audio worklet doesnt use postmessages anymore btw. I removed that way of commmunicating with the main thread. It's all shared memory in wasm now.
chaosprint
Cool. There is no doubt that you guys can nail it.
rikarendsmp
We also have a much newer version however the workload of 'everything' has been a bit overwhelming since we aren't actually making a synth(thats just an example application) but an IDE, designtool and a framework.
chaosprint
So is it going to be a Figma style tool?
rikarendsmp
Yep, with a visual studio style IDE for Rust. so Big project.

Why didn't you integrate with VSC?
rikarendsmp
We might, but only after we made our own. Our editor will finally break the barrier of inlining widgets/controls performantly. The editor is one piece with the visual designer (2 sides of a coin)
thumbuddy
Sounds cool I'll be keeping an eye on you guys

Mentioning that.. is this open source?

It's the iron fish project.

The Makepad fractal zoom example crashed my browser in all kinds of of ways that a browser is not supposed to be able to crash.
uglycoyote
I was disappointed in that example for a different reason. it ran on my phone, but when I pinch -zoomed (which is what I assumed a zoom widget built for web was supposed to support) it kept zooming towards the same point, which was a boring black spot. it didn't pan and zoom like I would have expected.

Does anyone know if the native UI framework supports being "hosted" in the sense that makes it useable for audio plugin dev (VST3 and others)?
rikarendsmp
We can definitely support it being hosted, however this is extra work on the platform side. VST is a licensing nightmare tho, i didnt really feel like stepping into that for now.
odiroot
Maybe try going the CLAP way instead?

As a hardware synth lover, I'm pleasantly surprised by how good this sounds. Great work!
rikarendsmp
Thanks :) All the work of 'this is not rocket science'

For those who haven’t seen it, Makepad is also an in-browser code editor with an open-source UI toolkit. Looks like this synth is one of the examples of the UI toolkit.

It feels much more snappier than Electron-based apps.
paulgb
Rather than going through the browser’s rendering engine, it’s entirely rendered on the GPU. Super impressive.
chaosprint
press option on mac. it's amazing

What does it do?
ledgerdev
It sort of zooms out and shows top level lines at regular size, but a mini-map like view of code underneath the top level. It's very smooth too.

Pressing Alt seems to invoke the same on linux/gnome, probably alt key on windows as well.
thumbuddy
Looks like old school synth software in a good way. Cool
bazeblackwood
The 6th note row from the bottom isn't working for me, for some reason! Otherwise, very cool.
srg0
It's very impressive.

I'd suggest to reset sliders on double click like most plugin instruments do.

I got just a blank page in dark grayish/brown color

What browser/OS are you on? Works fine here. Needs wasm+webaudio worklets and shared memory to work
beezlewax
This is awesome. I saw a talk on this the other day on YouTube.

This looks good even on my crappy phone. Is there a reason though that the html on hackernews renders text more sharply than the text on the makepad apps?

rikarendsmp
Yea we're struggling a bit with super sharp rendering on lower DPI screens. It's on our todolist.

Cool and very smooth. Shame Firefox doesn't support it (yet?).

It's very blurry though? Seems like it's trying to run at ~1080p (on a 1440p screen)

rikarendsmp
It shouldnt be 'that' blurry tho, sounds like maybe you have a browser-zoom level thats not 100%. I try to deal with that, but there are browsers that mess it up (safari can for instance)
lostmsu
Worked on Windows with Firefox.

It seems to be able to target app builds for everything but IOS. Is there a plan/timeline to add it?
