Hi guys,
We have a couple of tutorial videos that show exactly how to install a virtual MIDI cable (or port as David J says), as well as how to set up Garritan Libraries both in the Aria player and in Composer.
You can find those either on the
Tutorial Videos page on our main website or here on the User Forum in the
Tutorial Videos section. There are also template .not files for the various Garritan ensembles that you can download from either location.
Enjoy
Sherry
