This is a great tutorial (I've read it), but I think for a number of reasons JUCE[0] is vastly superior to WDL-OL (although if you're not already familiar with audio programming in C++, the docs can be a little daunting).
I would suggest starting by checking out some open source plugins and standalone apps made with JUCE[1] to understand how the applications are structured, and the docs[2]. It also comes with a (mostly) great IDE called Projucer which allows you to see your code changes reflected in your application (almost) instantly.
I remember trying this half a year ago, but the tutorial was already no longer applicable because WDL-OL couldn't be installed the way the tutorial covered for Windows. It explains how to do the setup using VS2010, which is genuinely obsolete at this point, so unless that's been addressed, I've not been able to actually make this tutorial work for me.
I'm making an audio plugin library in D, with the explicit goal to avoid all the pain of setting IDE projects, paths, and managing dependencies (all of this is done through the language package manager).
any intention of supporting VST3, now that Steinberg has officially discontinued VST2 development (i.e. there will never be a new 2.x version of the spec)?
great, thanks! I've been using Will Pirkle's books, which are really good, to learn how to build a synth and make audio effects (http://www.willpirkle.com/). Nice to have a second resource to compare against.
