A: The original preset banks are inside the Sounds folder as .fxb files (Steinberg Bank format). You can load third-party .fxp files from sites like PresetShare. Avoid .hyp files – those are for Hypersonic 1 only.
Hypersonic 2 was compiled with Visual Studio .NET 2003. Modern Windows does not include these Visual C++ 7.1 runtimes.
The biggest trap is downloading a malicious “Hypersonic 2 Setup.exe” from random file-sharing sites. Many of these contain miners or ransomware.
