The headline additions are two new plugins - Transistor Bass and FL Studio Mobile. The first of these emulates and expands on Roland's TB-303 Bassline synth, and is currently available for $49, while the second enables you to import projects from the new version of Image-Line's FL Studio Mobile app for Android, iOS and Windows.
A number of existing FL plugins have been updated, too - vectorial UIs are being rolled out across many of them - and there are workflow tweaks in various areas of the main application.
Find out more in the video above and on the Image-Line website. As ever, the FL Studio 12.4 update is free for registered users.
