.LOGICX File Extension
What is a LOGICX file?
Audio project package created by Logic Pro digital audio workstation (DAW) software; contains audio tracks on a timeline, which includes imported audio data, recorded sounds, and loops; also stores audio edits such as transitions and effects.
NOTE: When Logic Pro X was released in 2013, the LOGICX file replaced the .LOGIC file, which was used by Logic Pro 9 and earlier. Logic Pro X can open LOGIC files that were created by Logic Pro 5, 6, 7, 8, and 9.
