That’s insanely incredible and will let you fix that single mistimed beat with minimal effort.

Logic Pro X also brings an ‘arpeggiator’ which can automatically convert chords into arpeggios for giving your music a more complex feel. There are also a ton of pre-recorded sounds, and patches that you can freely use in your workflow, along with Apple’s insane amount of plug-ins that are shipped with Logic Pro X (there’s over 60GB of additional assets you get with LPX!).
