I was informed that I could copy songs with and without cdg.
I tried to copy to copy a couple - one with cdg , one without. When trying test CD got an error. Both songs copied the same with CDG. Is it possible to mix?

I am confused. Do you mean you want to combine audio CD songs with Karaoke CDG songs on the same disc? If so, this is not possible directly with Microstudio. The two disc formats are very different, and not compatible.

The only possible way to add an Audio CD song to a Karaoke CDG disc is to convert the Audio CD song into a Karaoke CDG song using Karaoke Home Producer.

Let me know if this is not what you were asking. :w
