Ok, so the soundfont is Equinox Grand Pianos, and its my basic go-to soundfont.
The FX chain is fairly complex, here it is (ordered from left to right):
The sidechain was actually bypassed later on, when rendering to stems.It's there for sidechain only, and it does not affect the sound. Why didn't I put it on the end? I have no idea, I should've done that.
The sound was also post-processed in bitwig afterwards, after it was rendered as a stem.
Basically some stereo widening, transient control and more eq-ing. (sorry for the grayed out pic, I was too lazy to turn my audio engine on).
So for the 'house piano' sound you generally just want to have a heavily compressed piano sound, which has been EQ'd to sound very bright (see how I boosted a shitload of highs and mids). I actually limited the sound here (limiters are just highly specialized compressors) as I really like how limiters sound, just personal preferenece, and the fact that I have yet to become good at compression

. I have to say that the piano in 'Slow Down' did not turn out as clean as I wanted it to, and that's probably because I went a bit too nuts with the effects.
Anyways, hope this was helpful.
