I had a need to edit one plug-in for R19. Most likely it is written in C ++.
If there was a exe file, there would be no problems, but here cdl64 is a proprietary file.
The plugin folder contains "h" and "res" files. For example, I edit a line in one of the file (the name of the item in the plugin). But when you edit them, for some reason, there are no changes in the plugin itself. So I thought it was the cdl64 file.
I will be glad if you can help me
