Hello,
I have found this rather neat free piano VST named BitKlavier at https://bitklavier.com/#aboutBody
One can download the IOS or Windows versions here:
https://bitklavier.com/#aboutBody
and the necessary Steinway D sample libraries from the various links provided here:
https://bitklavier.com/the-bitklavier-grand
I found also Linux native builds, either .RPM and .DEB.
On Debian and derivates, BitKlavier can be installed by issuing the following commands:
echo 'deb http://download.opensuse.org/repositories/home:/c71b67b6:/fa2aa07a05c1/Debian_12/ /' | sudo tee /etc/apt/sources.list.d/home:c71b67b6:fa2aa07a05c1.list
curl -fsSL https://download.opensuse.org/repositories/home:c71b67b6:fa2aa07a05c1/Debian_12/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_c71b67b6_fa2aa07a05c1.gpg > /dev/null
sudo apt update
sudo apt install bitklavier
