NO MIDI DRIVER + NO MIDI DEVICES TAB IN AUDIO/MIDI Settings

Hi guys...

I'm trying to send MIDI signals via Wi-Fi, from Touch OSC on my iPad to an application on my iMac.

I need to configure the wireless MIDI settings, but A) I have no MIDI Driver and B) when I go to AUDIO/MIDI Setup/Settings, there is no tab for MIDI Devices?

All help would be greatly appreciated!
