I read specs of 2018 and see there is small enhancement to audio editor. but maybe biab can enhance so it support ARA interface and melodyne. some DAW support this. waveform tracktion cost 99$ and have a ARA interface support and cheapest melodyne build in the bundle. and if a user like edit more he can buy update to melodyne

The ARA interface allow direct access to audio data, so melodyne can work in as a buildin editor. with cheapest melodyn bundle it is possible to rearrange the real tracks too. because BIAB is mostly audio based tracks, the ability to reslice or change note number is important to make more creative songs with real tracks
