Well, parsing a self-contained S-expression is not that bad and I have already written the parser. References between music expressions (like cue notes, or staff change events) might be tricky, but they are tricky even if I had direct access to the original data structures, as I anyways need to translate them to native Haskell data. > GHC has a FFI interface for C++, Not really. GHC has a C interface that is usable, but generating bindings to big libraries such as Guile will require a lot of manual work. There is a tool called hs-bindgen in development which facilitates this, but it is not in a usable state yet. Anyways, thank you for your suggestion! -- Aura
