Friendly greetings !
small intro :
I literally started yesterday with Juce.
I did some quick and dirty VST dev before that, using JSFX/ReajJS/Jesusonic/Geep-Jeez just to understand the basis of signal processing.
I also built & tested an hello world and noise generator VST with juce/projucer. It works <3
Thanks to online tutorials (both video & text) and documentation.
the big deal with new features :
Here is my problem, it’s a “simple” one (and therefore the most complicated to answer 
)
In projucer i see you can create gui component with a nice graphical interface.
I also noticed the new “DSP tools” feature.
It seems there is the “new way” of doing stuff and the “traditional way”.
The new way seems to be a way where everything is separated and possibly autogenerated by projucer, the traditional way is doing everything (or a lot of things) programmaticaly in visualstudio/xcode.
The majority of online beginner resources are, obviously, oriented on old release of Juce since 5.1 is very new.
I’m confused about how to organize stuff.
Should i create 1 gui component in projucer per, eg, slider ?
What about this new DSP tools thingy ? Should i care about it ?
Should i write my core algorithm (eg : 4 pole LP filter) directly in the processblock or should i create some kind of processor component/dsp module/something, then somehow call it from here ?
Well… I HAVE NO IDEA ! And here i am 
i understand the parent/child relationship between processor and editor, and i’m assuming i understand the same relationship between the editor and its GUI component (i didn’t try yet so we’ll see).
I’m not a professional coder but i have 30+ year of experience in coding random stuff. (my github : https://github.com/ker2x?tab=repositories ) so don’t be afraid to explain it the hardcore way. I know i’m asking for trouble but it’s just to avoid generic answer like “you should learn the basis of OOP first”.
I’ll find a way to deal with the small stuff, even if i have to read the juce source code, but the big picture of juce doesn’t have much explanation and i’d like to get started in less than a year by avoiding reading the whole juce code if possible 
thank you very much for your attention, have a nice day.
hugs
EDIT : in the meantime i’m watching this : https://www.youtube.com/watch?v=SJXGSJ6Zoro
EDIT2 : from what i read in VST example, everything is packed as much as possible in as few files a possible. Should i stick with this and also not use the GUI editor ?
