To make a direct output connection
µ
Click the Port menu in the object’s Parameter box, and choose a MIDI output.
The Port menu lists all MIDI Outputs, plus the following options:
• The Off setting completely disables the connection to the MIDI interface port.
• The All option routes the object’s output to all available MIDI ports. This may be useful
if the device is sending a pulse, for example.
Note: If you have a MIDI interface with more than one output port (or even several
interfaces that can be stacked), you can set up a direct connection to one of the individual
ports (1 to 63) of that (or those) interfaces.
Any object with a directly assigned output is indicated by a white triangle on its right
side. The triangle is hollow when there is no direct assignment.
