Question: Re: relative VST (and other paths) - I asked because on Windows USB sticks might not always get the same drive letter... so it would be extremely useful if we could link VST folders to a portable Reaper install without worrying about it. Sorry for not following rules! :$

Question: Is it possible to set a VST path relative to Reaper's portable folder? Would be nice to have if not. Something like %REAPERPATH%/../VST for example.

There is projectcontext.h/.cpp in WDL, and then you end up doing loops which end up reading a line at a time and parsing the lines with WDL/lineparse.h, with any <XYZ starting a new block (projectcontext also has a function to ignore unknown blocks). Comment...

Question: Sorry, I think I found the answer to my own question. Calling PreventUIRefresh(1) before TrackFX_SetParamNormalized() on the audio thread did the trick. And after that in the main thread: PreventUIRefresh(-1). In order to make this a question: Is this the right approach? Thanks!

No this is a very bad idea. In fact, doing pretty much anything via the REAPER API from a thread other than the main thread is likely to be bad/unpredictable. How are you in (one of) the audio threads to begin with? Don't answer here, post on the developer forum. Comment...

Question: Hi Justin. Do you see a way to set FX parameters in the audio thread? Seems like calling TrackFX_SetParamNormalized() in the audio thread makes REAPER hang when attempting to write automation and no automation lane exists yet. Same goes for CSurf_OnVolumeChangeEx() and similar functions.

Question: I hope this doesn't violate the policies regarding Reaper questions... This is really more of a philosophical question. I love that this happened, but what prompted you to include notation support in Reaper, which had been primarily an audio based application? BTW - the fact that it exists in such a mature implementation is nothing short of a miracle (com
