I recently started exploring sf2 (soundfont) files for my acoustic piano sounds. I’m using a free soundfonts player Sforzando and acoustic piano sf2 files free to download from Soundfonts4you. There are some great sampled pianos there, especially Yamaha pianos such as the C5 Grand and Chateau Grands. I’ve tried a number of VST piano apps (Pianoteq a long time favorite), but soundfonts are now my GoTo acoustic piano sounds.
This has run with no hitches in Cantabile and Windows
