Hi Alexis,
the function of the three pedals is well explained here :
https://en.wikipedia.org/wiki/Piano_pedals
About the middle one :
...
The middle pedal may sometimes lower a muffler rail of felt between the hammers and the strings to mute and significantly soften the sound, so that one can practice quietly (also known as a "Practice Rail"). "
Yes, from your description I have a "Practice Rail".
It does more than just make it softer though ... I am not skilled enough to describe what I'm hearing, but the Practice Rail pedal somehow changes the tone, almost as if there are less overtones, using it makes it somehow less vibrant and clear.
The thing is, I have a MIDI piano recording that I'd like to use that Practice Rail sound on!
I guess Practice Rail sounds vary from piano to piano, and so there would be no way I can ask the community how to mimic what mine sounds like (I'm not set up to record acoustic piano well at home, I don't actually have a studio).
Given all that ... I was thinking maybe applying a high pass/low pass filter might help ... ?
Would anyone have any other off-hand suggestions by any chance?
Thank you!
