Setup
Once you have your CVs entering the plug-in (a simple matter of audio routing) you will
also need to set up the MIDI target i.e. the destination to which the plug-in sends MIDI.
This will either be a hardware MIDI port attached to your computer, or a virtual ‘bus’ used
to route MIDI to other software within the computer.
Selecting the Target
The field along the bottom of the plug-in GUI shows its MIDI target. It is possible to type a
value directly into this field, but it’s usually much simpler to browse for the target, using
the ‘Browse’ button to the right of the field.
Clicking this brings up a
dialog which lists all the
MIDI destinations that are
available. Simply click on
the service you want from
the list and click OK.
Using inter-application busses
If you want the plug-in to control other software on your computer, rather than controlling
external devices, you will need to route its MIDI output to a software bus.
On OS X, you can use the system’s built-in ‘IAC Driver’. To set this up, open the ‘Audio
MIDI Setup’ utility, show its MIDI Window, and double click on the IAC Driver item that
you see there.
On Windows, you will have to use 3rd party software, for example Hubert Winkler's
Hubi's Loopback Device or Jamie O'Connell's MIDI Yoke (both freeware).
