I think the threat to Realband won't be from another DAW. Anyone who has played with SUNO for any length of time can't fail to be impressed by the quality, so how long will it be before you can input a chord sequence into SUNO? This then becomes, essentially, BiaB with Ai tracks instead of realtracks. There's no doubt that the realtracks are good, but they have their problems - often on a guitar rhythm track, the guitar will use a chord inversion which isn't the one a live player would use. Similarly, lead instrument solos can end up with progressions which are not logical, because they've been welded together without reference to continuity. This doesn't happen with Ai. The next step is likely to be something which looks like Realband, but with regenerating Ai tracks. Let's hope PG does it before SUNO. The stem splitter shows that PG is heading in the right direction, but I'm not sure how much catching up they have to do.
