I can't find it listed in any of the "What's new" updates and it's a bit rough around the edges, but along with the BandLab MP3 option now built into the Export dialog, it points to work being done on integration between Cakewalk and BandLab's existing products.
To try it out, open a new project with at least one audio track. Start BandLab Assistant, and click on Sounds.
From Sounds, choose any of the Loop Packs, and audition a loop by clicking on the waveform icon to the left of the name of the loop. Let the loop finish (important). After it has finished, click and hold on the space to the right of the name of the loop you just auditioned and drag it into the audio track.
It should drop right in to the track. If you don't wait until the loop has finished auditioning, you'll get an error message, and I've found that I have to be pretty picky about exactly where I click and drag in BLA to get it to work, but work it does. It works with cells in the Matrix view, too.
And it demonstrates that the sometimes-maligned BLA is on its way to being a pipeline for transferring tracks from BandLab to Cakewalk. Bandmate records a track, uploads it to BandLab, you drag and drop it right into a project. A web-based content management system for multitrack recording!
(Or, for the tinfoil hat crowd, BandLab is that much closer to being able to slurp your just-recorded tracks from your hard drive on to their server, for drug-addled youth to rap over with depraved rhymes about weed and booty.)
