Summary0003949: Graph in Invada Compressor LV2 plugin does not match parameters
DescriptionApologies if this is not an issue in ardour - I'm reporting it in case it is.

If I insert the Invada Compressor LV2 plugin (mono or stereo) in a track, I'm presented with a very nice interface to configure its parameters, where I can see a graphical representation of the effect of the compressor (an output vs input dB plot). This plot has the usual straight-line shape with a sharp kink at the threshold, as expected. However the right portion of the curve is incorrect. For example:
- set threshold to -10dB
- set ratio to 2:1
I would expect that a make-up gain value of 5dB would make the output 0dB at an input of 0dB. But it doesn't. You need a make-up gain of about 3dB to make the curve hit (0dB,0dB). Similarly for other values.

I haven't tried to figure out what the actual connection between the graph and the parameters is, or whether it is the slope or the offset that is wrong, but it would be easy to find out. Might this be something that ardour is doing wrong? Else, where should I report this?

as you gussed, this has nothing to do with ardour. the GUI is part of the plugin. ardour does nothing but make it appear on screen. you need to talk to the author of the plugin.

Thanks. I'll report the problem via Ubuntu then, and ask them to upstream it.

please don't do that, because they won't do that. they have *never* "upstreamed" a bug in ardour to us, not once.

late :-) ok, I'll try to find the correct place to re-report this then.
