Logic Pro 7.1 – MIDI Setup (2005-0905) 12 of 13

Live Routing

Example A

The example above illustrates to possible connection of two separate Logic applications running on two separate computers, sending MIDI back and

force over the network through “virtual MIDI cables”. One computer could run Logic as a regular sequencer and the second logic computer could

function as a audio instruments playback machine, where you send the MIDI messages from you Logic tracks of Computer A to the (max 128) audio

instrumnets of Computer B.

Example B

You could have your G5 hooked up to all the MIDI gear in the studio and when you or a client comes in with his Logic song on his Powerbook, you

don’t need to transfer the song and all additional media files to the G5. You just have both computers connected to the network and configure the

Network Device on both machines, so you can send the MIDI messages direct from your Logic app on your Powerbook to the G5 and all its connected

MIDI gear.

Example C

You can use the Network MIDI Ports also for a network jam session, where all the participating computers contribute their connected MIDI gear to a

“virtual pool” of availabel MIDI devices and you can setup AMS which controller plays which sound device.

You accomplish this with a feature called

Live Routing

For the Logic app Network MIDI Ports aren’t any different then real MIDI Ports from a connected MIDI interface. They show up in the “Physical Input”

object as a MIDI In Port and also appear in the popup menu of the Instrument Object Parameter Box as MIDI Out Port. So you have to use a MIDI

application if you want to play any MIDI device over the network.

The “Live Routing” feature however lets you use a Network MIDI Port to connect any MIDI Device in the AMS configuration window of Computer A with

any MIDI Device in the AMS configuration window of computer B. i.e Your USB Keyboard on your Powerbook can play the Gigastudio connected to your

G5’s MIDI interface.

Here are the rules:

• Each individual Network MIDI Port (Session) has its own Live Routing settings

• Upper Popup menu lists all the available Devices that can send MIDI messages: MIDI Source

o Any MIDI Device that is connected to a MIDI in connector of your local MIDI Interface

o If there is no Device connected to the MIDI In connector of the MIDI interface, then the Port Name of the MIDI Interface will be listed

o All the Network MIDI Ports will also be listed with the prefix “Network”

• Lower Popup menu lists all the available Devices the can receive MIDI messages: MIDI Destination

o Any MIDI Device that is connected to a MIDI out connector on your local MIDI Interface

o All the Network MIDI Ports will also be listed with the prefice “Network”

By using the Live routing feature in the illustration below, you can play the Emu on Computer B from your Karma (connected to Computer A) and at the

same time play the S760 (on Computer A) from the Keyboard connected to Computer B as if they would be connected through virtual MIDI cables (pinl
