Adding New MIDI Devices to the Environment: A Walkthrough
Adding a new MIDI instrument to the Environment will allow you to select it as a distinct item from the Reassign Track Objects menu. First, open up the Environment window, which is Cmd + 0 or Windows > Environment. With the Environment open, select the layer selection menu to the top left. From this menu, select the MIDI Instruments layer abbreviated to “MIDI Instr.” This layer should see a GM Device, which is sometimes routed to the Quicktime Music Player.
To create a new instrument, choose the New menu. There are plenty of options available here, but namely we’re concerned with either a new Instrument or Multi-Instrument. An “Instrument” in this case is an instrument that has only one MIDI channel, such as synthesizer. The Multi-Instrument alternative is for use with multitimbral MIDI devices such as a sound module or external sampler. It is important to establish which type your device is before connecting as it will make your selection easier from a track in the Logic Pro Main Window. When this appears, you will need to route it out of a physical MIDI output. To do this, select the instrument object and visit the Inspector on the left to select the port it will output from.
If you have chosen the Multi-Instrument option, a grid with 16 numbers will greet you, and they’ll all be crossed out. This is so that you can specify how multitimbral your device is. For example, some synths only can receive eight channels of MIDI, rather than the full quota of 16. In this instance, simply don’t deselect the last eight. This will ensure that Logic can only talk to the eight live channels. While you’re here, it is really handy if you label the instrument by either selecting the object and clicking on its name in the inspector or selecting the Text Tool from the Click Tools menu. Your device will be labeled and available from the track assignments in the Logic Pro Main Window.
