Apple has announced a new update to its class-leading DAW for MacOS, LOGIC PRO X, to 10.4 with new virtual drummer profiles, smart tempo features and a host of new useful effects plug-ins for both tracking and mastering. Free for existing users.

Notable are is the new ChromaVerb algorithmic reverb, and Step FX which adds rhythmic multi-effect processing using 3 powerful step sequencers and an X/Y pad. Also, stand-alone Mellotron, and new horn and string section libraries.

The one annoyance for existing loyal Logic X users is that the update/upgrade will only be available to those running OS X 10.12 (“Sierra”) or higher; and those who chose to “freeze” their older Mac Pro towers on “El Capitan” will not be able to download the upgrade from the App Store. (Editorial Note: while it may be possible to install the new version onto a Sierra machine, then “copy over” to your El Capitan Mac, I don’t know of anybody who has yet tried this.)
