ok ok i spent a couple minutes learning to use it and so basically i put in the utaus in the settings, i selected the resamplers and stuff, i added my voicebanks, i added another track set to utau, i selected the vb at the bottom that says singer, and since i was using a vcv voicebank, i had to type it in like you do in utau not sure if this helps because i literally learned this all thru trial and error
also if you know how to use vocaloid 2, its kinda like that except different
edit: its super scuffed if you want to use anything thats not a cv voicebank
