I'm a new user of Utau and had just finished recording a cv voicebank. So Whenever I try to Initialize the frequency map it always shows this error, any reasons to why this is happening? (this is just a test vb btw)
That's not an error. That's the standard message to confirm you wanna remake the frq file.
In the chart behind the popup, in the frq column, see the O? That means it has a frq.
To generate multiple frqs at once, go to Edit > Select Multi, click on the first sample, hold shift, and click on the last sample. They'll all be highlighted and you can hit 'Initialize freq. map' to make frqs for all of them. It'll save you some time later.
