After explaing about the new Suno feature, "persona" and uploading a track that failed to live up to expectation (see "Lost In Silence), I was able to generate a track which created a duet (alternating male/female vocals) which satisfied me.and I felt worked, to a point. Although I used tags to identify which sections/lines were sung by the "duetists" or both, the AI still randomised them to a certain extent. But I think I got what I wanted in the end.
This duet (Suno requires a name for the personas) I called Just-In-Love. If Suno wants a name, Suno gets one; Just having a little fun withe the names.
