Messages

bang

In left inlet: Same as int, but doesn't send a set message after setting the umenu items. The equivalent message to bang for retrieving input device names is -1 in the right inlet.

int

Arguments

index [int]
In left inlet: Causes midiinfo to send out a series of messages containing the names of the current MIDI output devices. Those messages can be used to set the individual items of a pop-up umenu object connected to the midiinfo object's outlet. The number received in the midiinfo object's left inlet is then sent in a set message to set the currently displayed umenu item. In right inlet: Causes midiinfo to send out a series of messages containing the names of the current MIDI input devices. Those messages can be used to set the individual items of a pop-up umenu object connected to the midiinfo object's outlet. The number received in the midiinfo object's right inlet is then sent in a set message to set the currently displayed umenu item, unless the number is less than zero, in which case no set message is sent.

controllers

Arguments

index [int]
In left inlet: Causes midiinfo to send out a series of messages containing the names of all MIDI controllers (devices that transmit MIDI) in the current MIDI setup. Those messages can be used to set the individual items of a pop-up umenu object connected to the midiinfo object's outlet. The word controllers may be followed by a number, which sets the pop-up umenu to that item number after the menu items have been created.

Output

append

Immediately after sending the clear message, midiinfo sends an append message for each MIDI input or output device name, to set the items of a connected umenu object. The device names will be sent out in the order in which they appear in Max's MIDI Setup dialog.

clear

midiinfo first sends a clear message out its outlet to clear all the receiving umenu object's items.

set

If the incoming message to midiinfo is an integer greater than or equal to zero, a set message is sent after the append messages, to set the currently displayed menu item.
