Specifies the port for transmitting MIDI program change messages. When a letter argument is present, channel numbers greater than 16 received in the right inlet will be wrapped around to stay within the 1-16 range. If there is no argument, pgmout initially transmits out port a, on MIDI channel 1.
A letter and number combination (separated by a space) indicates a port and a specific MIDI channel on which to transmit program change messages. Channel numbers greater than 16 will be wrapped around to stay within the 1-16 range.
The name of a MIDI output device may be used as the first argument to specify the port. The name 'none' can be used to prevent the object from transmitting MIDI messages on any port.
A number alone can be used in place of a letter and number combination. The exact meaning of the channel number argument depends on the channel offset specified for each port in the MIDI Setup dialog.
matchport [int] (default: 0)
If the port argument doesn't match an existing port or device name, set the object's MIDI port to 'none'.
Set the object's MIDI port based on a device name. The attribute will attempt to do a case-sensitive partial string match based on the attribute's value.
Common Box Attributes
There are no outlets. The output is a MIDI program change message transmitted directly to the object's MIDI output port.
