Hi there,
There's something I would like to understand about virtual endpoints:
If a MIDI software does not connect directly to the hardware device (say a
GM hardware synthesizer), but creates a MIDI virtual endpoint: other
applications will see it and offer the user to use it as a MIDI input, so
that's OK.
But how can the user connect this virtual device and a hardware device
together? Under OS 9 and MIDI Manager, there was a program for that where
you could see all devices (virtual and physical) and establish connections
between them. Apparently, virtual endpoints do not appear in the "Audio MIDI
Setup" application. So how do you do virtual MIDI routing inside the
computer?
Take this application for example:
http://www.versiontracker.com/moreinfo.fcgi?id=16286&db=mac
It creates a virtual device to send MIDI data, but how do you get this data
out of the computer to the MIDI hardware?
I'm asking this because in my app, I'd rather create a virtual input and a
virtual output and don't bother creating a user interface ;)
