If you create original music using Logic Studio or Logic Pro on Mac OS X, you can greatly enhance your recording experience by connecting a simple MIDI keyboard. By connecting an external digital instrument, you can take advantage of Logic's built-in software synthesizers, like the ES1, the ES2 and the EFM1. This simple integration turns your simple recording software into a full, portable music studio, giving you a wealth of unique sounds with full editing capabilities.
Plug your MIDI interface, or any MIDI-to-USB adaptor, into a USB port on your Mac. If your interface includes a CD-ROM with software drivers, insert the disc into your computer and click the installer.
Connect your MIDI keyboard to your interface or adaptor. Using a standard five-pin MIDI cable, plug one end into your keyboard, through the "MIDI Out" slot, and one end into your interface, through the "MIDI In" slot.
Open Logic, available in your "Applications" folder, and create a new music project. Select "File" on the menu bar and click "New."
Click "Logic" on your menu bar and select "Preferences. Click the "Audio" icon at the top of the "Preferences" window and select the "Devices" tab directly below.
Locate the "Device" menu in the centre of your "Preferences" window and select your MIDI interface from the list. Click the "Apply Changes" button in the lower left corner of the window.
Create a new track. Click the "Track" tab near the top of your editor window and select "New" from the drop down menu. A new track heading will appear in the left column.
Hold the "CONTROL" key while clicking the track name in the left column with your mouse. On the pop-up menu that appears, select "Reassign Track Object" followed by "Audio" and finally "Software Instrument." Assign a number to your track and it will become enabled for MIDI recording.
Assign an instrument setting your track. Open your mixer window by clicking "COMMAND" and "2" simultaneously on your keyboard. Locate your track number on the mixer and click and hold the "Input" button. A list of your software synthesizers will appear. Choose a sound setting and you can begin recording through your MIDI keyboard.
