Honestly no, I downloaded the stems but never used them - their fine grain editor in the pro mode is... insanely good, I feel like I'm a secret shill here pawning for Suno but I'm 100% not - their editor really is magic when it works (about 75% of the time) - I use Abelton for just my regular post mix down i've done for years on all the stuff I make, so I basically just master there at this point.
