Looks like that is the original thread. Posting it here easy finding. During the migration to the new Forum some of the attachments on posts got “lost.”. I believe the Tool is still floating around somewhere and as soon as @taktik (I think he’'s the one saving lost attachments) sees this it will probably be put back in the linked thread.
This Tool may also be of interest, and has been updated for Renoise 3.1.
