hmm, that is weird.

inside your ardour project folder there should a lv2 bundle/preset of that carla-rack instance. can you try to find it and upload it?

have you experienced this with other plugins? native ones? some other win64 vst?

rghvdberg commented 9 years ago

this is the first time i've noticed this

there were a lot of files/directories in the plugin dir, I guess this is the one. (removed the rest and the plugin still loads) EDIT---> the file .... https://www.dropbox.com/s/sgfzhiou1d5arza/1771.tar.gz?dl=0

update: parameter change when saving preset ... video ! https://www.youtube.com/watch?feature=player_detailpage&v=_1li8tMfrSg

Just tried it with obxd as win32 vst plugin. Same thing happens. Parameters are changed when saving preset.

falkTX commented 9 years ago

what about native ones?

hopefully I'll be able to look at this today..

rghvdberg commented 9 years ago

Native Noize Mak3r VST plugin. Same thing :-( But I guess this will make it easier to debug because apparently it's not a win32/win64/bridge/wine thing .. but a 'normal' bug :-)

falkTX commented 9 years ago

ok, I can confirm this issue.

investigating...

falkTX commented 9 years ago

something is wrong with charlatan, after loading a project with it inside it will sound different. but I have right now the old (unclosed) and new project loaded at the same time, and the parameter values are the same. still, it sounds different (high pitched on the loaded project)

hmmm

falkTX commented 9 years ago

Thanks for the report, I found some minor things with carla as plugin that needed fixing thanks to this.

The fact that some plugins sound different when loading their preset/project is a different issue. If you experience it and it bothers you too much please fill a new bug report.
