why when saved to a file, and opened for play just his voice alone gembar not visible at all
I don't understand what you mean. Please describe the problem better. What type of file did you save? What program did you use to open it? What is "gembar"?
If you have a problem with a specific project, either attach the .scribe file here, or save your project to the cloud and tell customer support the name of it.
