The cat is indeed not only cozy, but also soft!
It was a VST piano. I think I used "The Giant" from Native Instruments? So technically it was a real piano at some point ;)
When I re-listened earlier today, I had a similar thought to it being warm and pronounced, perhaps a little too much compared to the strings..... but I guess that's what happens when you mixdown the night before a deadline, and it worked out well enough.
Thank you for listening!
