Bitwig has been adding more and more great features to their DAW with each and every update, and 2.3 is definitely not something to sleep on if you're a user.
Bitwig Studio 2.3 adds a load of features that have been much requested by their community, which expand the sound design possibilities.
Some of the additions include the Phase-4 synth, a massive new phase manipulation synthesizer, new voice stacking capabilities, new expanded views for 7 of their inbuilt devices and some major improvements in time stretching.
