Sorry if that is mentioned somewhere, Google was not my friend this time...
How to get REAPER hostcb from "V..3" compatible plug-in?
There is documentation how to do this from V..2, but ABI is completely different. Is there any interface UID for that?
PS. I do not want to mention related company name nor any trademarks of it, that is why I write a bit cryptic
I was almost ready to apply for a license, but I have started to read it carefully... Not only I have to do a lot of small things, I also HAVE TO update to any new version they decide to release within a year, and they CAN cancel the license without any explanation. Sorry, without me...
Since REAPER has no own processing plug-in format, I have to use "V.." compatible ABI. Just for fun, I have decided to check V..3 format. Works fine (from plain C, without any SDK), but I am stuck in getting REAPER pointer.
