This has earlier versions of MFConv and MFPlay:  MFConv is at Edition #10 and
now includes an Instrument Patch Renumber option.  Edition #9's Channel-Moving
option is still intact, too.  MFPlay is still at Edition #9 here.  Related
docs included, making this the complete package you'll need for these
editions.  This is missing the SMF Fmt1-to-Fmt0 converter, for one, so instead
download the "other" package.  (This has been uploaded purely for
completeness' sake and as a "backup" to my collections.)
