I found it at ftp://ftp.cs.uu.nl/pub/MIDI/PROGRAMS/mf2tsrc.zip Last-Modified: Thu, 04 Apr 1996 12:25:35 GMT. Is this what you are were referring to? Is this the last version? It needs a bit of an update to compile it with modern gcc: http://rg42.org/_media/wiki/mf2t_fixes_for_gcc4.diff but then works just fine. A handy instrumentation tool. Does anyone here know Piet Van Oostrum? He wrote mf2t. The source-code comes without any license. There are various binaries for Windows95 and 98 and XP floating around; but it may be bit too over-optimistic to assume that it is public-domain. If not I may try to drop him a line: http://people.cs.uu.nl/piet/ ciao, robin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
