Mine's in, albeit like 40 minutes late.
Yes, BandLab is epic in total suckage because it has no ingrained ability to slow down or speed up tempo, so I had to literally take the song, replicate it between several different files, and try to splice it back together with the variant speeds and key changes...
...*shrugs*...I tried. I'm probably going to switch to an actual DAW rather than the online thing, because it's busting my proverbial and metaphorical balls almost every single time I try to produce/compose something, and I'd rather not have a near-mental breakdown every time I make a song, lol.
