This (@syntax) is in (OBJ)FPC mode, your example is Delphi mode.

OK I stand corrected, re. the pointer() cast... 

but then why not declare in a public header for this wrapper:
type
  TSoundtouchCreateInstanceProc = procedure;

then
soundtouch_createinstance := TSoundtouchCreateInstanceProc(DynLibs.GetProcedureAddress(...));

(nb. delphi mode)
