I see that some users in our forum use Vocaloid to sing the melody, backed by BIAB.

How do you do that?

I know how to create a melody in Vocaloid Editor 4, but after I have the melody, how can I integrate with BIAB so that I have a suitable backing track?

Thank you

It's not listed as 'vocaloid', it's listed as 'sinsy'.

You need to upload your lyrics to the remote vocaloid engine.

Search the integrated Help for 'sinsy', or check out the integrated PDF manual (from the Help drop-down menu), there are several references, and the process is explained fairly well.

You can just save to wave and import to Biab ? or:

Vocaloid 4 should have a VST you load into the Host DAW, it also has rewire so you could try the ReWire plugin in RealBand http://www.energy-xt.com/index.php?id=0115
