This is a convenient plugin that automatically provides backing. It can also play single notes. The sound quality is good, so I think it can still be useful today. It's an old 32-bit plugin, but it can still be used with bridge software. Due to its age, the upper left corner of the box is slightly torn. The CD inside is in good condition. CD reading has been confirmed. It can be installed on both Windows and Mac. Operation on Windows 11 has been confirmed.
