This site has several harpsichord sample sets. They are free. You could use the soundfont files with jOrgan or similar software. All you would really need is a MIDI keyboard and computer.https://sonimusicae.free.fr/blanchet1-en.htmlI hope that could help. Unless you are looking for a physical electric harpsichord instrument. https://www.roland.com/products/en/C-30/index.html
