Ok, so i will only talk about it as a legacy interface superseded by seq that controls midi events flow. > > - What is 'virmidi' for?

Do you mean that virmidi ports are simply like four pipes that send what they receive?

It seems that my understanding of the previous part was wrong. Maybe is that one right: 'Virmidi is a seq wrapper on rawmidi, that provides seq compatibility to drivers that only support rawmidi.' > ciao -- David García Garzón <[EMAIL PROTECTED]> Phone: 034 93 542 21 99 Music Technology Group, Institut Universitari de l'Audiovisual Universitat Pompeu Fabra ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
