Key Commands window The Key Commands window is used for the assignment of key commands to computer keys or to MIDI messages. key focus The selected, active window, is said to have key focus in Logic Express. Many key commands will only function when a window has key focus. The Inspector also updates to reflect the parameters of a window with key focus. latency You may notice a delay between playing your keyboard and hearing the sound. This is a form of latency. A variety of factors contribute to latency, including the audio interface in use, audio and MIDI drivers. One factor under your control, however, is the I/O buffer size, which is set in the Devices preferences. legato Method of musical performance that smoothly connects one note to the next. level meter A meter that monitors audio input or output levels to or from your computer. You use the level meters in Logic Express when recording, arranging, and editing audio files, and when creating a mix. LFO Abbreviation for Low Frequency Oscillator.

The number on top is the left locator; the number below is the right locator.
