UltraDAW now support VST3 / CLAP plugins
VST3/CLAP support is finally done. But it definitely needs more in-depth testing. As for the formats themselves - VST3 has too many helpers and too much mosaic documentation. Some things have to be literally searched for bit by bit on the Internet. Steinberg's own documentation system is completely confusing - a bunch of sites, a ton of links. Of the ton of SDK files, you actually need 3 dozen. Very difficult. With CLAP, the situation is completely opposite - everything is simple and clear. One header clap.h, and an extensions system. Very easy to embed into the code. True, unlike VST3, some difficulties were precisely in the lack of documentation. Of course, the comments in the header files are written very well and clearly, but some things were not immediately clear. For example, start_processing / stop_processing is it even needed or not? But overall - a good format.
In the near future - I continue to do UNDO/REDO and write workflow documentation.
