Okay… reading more about this, and you were right! I need a Windows machine in order to build Repitch as Windows VST3. I’ll look into using Github Actions for this, or otherwise I’ll build a Windows version next time I have access to a PC. Thanks for all the help troubleshooting!
I had a go at building a Windows version – give it a try when you get the chance! I have no way of testing it myself unfortunately 🐒 https://github.com/maxwellpollack/repitch/releases/tag/v0.3.5
heya ! this works ! i will add: the only file necessary for it to work is the Repitch.vst3 file, and in fact the files contained in the _MACOSX folder will confuse FL Studio and get it to detect the wrong files. so it should work perfectly fine with only the .vst3 file. but thank you so much it works great! <3
