--- Comment #13 from Michael Stefaniuc mstefani@winehq.org --- OK, it makes sense now: Gothic uses pre-DX8 creates dmusic files. DMUS_IO_STYLENOTE and DMUS_IO_STYLECURVE have fields with "DX8" comment. DMUS_IO_STYLENOTE with size of 22 corresponds to the pre-DX8 version.
Most likely DMUS_IO_STYLEPART had at one point in time the dwFlags field added too. I'll need to review the whole change from 8e596f4ddba3d19d6eea645e59d54101f93aa2bc and add code to handle pre-DX8 files too.
