I am sorry for creating confusion with the objects of the mails ... I continue here the yesterday debate about the sfz from London Philharmonia samples. I don't understand why Sonatina uses one samples every three note, while London Philharmonia provides one sample per note. Something like that implies a hard code for file names or a strict directories organization to obtain every information needed (for ex: instrument name, note, velocity etc). Every project has different needs.. otherwise, we can think to a tool to make easier creating sfz files, but user will have to insert sample by sample, so it won't be automated.
