Rotation and live playlist

Good afternoon, use the Mbstudio some years, much like the software. The only problem I can not solve and that bothers me is the fact repeat the songs. His tendency is to put the same songs more or less the same times. Even with the option of not repeating the same singer in space 3, 4, hours .... he does not respect the criteria. You lose a lot of the songs in the rotation. I wonder with the best setting to prevent this from happening? Another very negative aspect and that does not happen in most of the software is not having in-built the live playlist. Ie instead of opening side must be fixed on the couch, not all radios use two waxes. Sending a photo as an example that should follow. is very stressful to be always open and close, users do not like. On top there is a space mbstudio which is empty on the screen.

Thank you.

I'm glad for the change, from what I saw I liked! Thanks for the answer. Tomorrow send debug. You can send me the correct settings of the songs?

Thank you.

The songs that were included were from out of libraria is a demo version of mbsudio a laptop, it is not the pc studio. yes this is all in libraria. Thank you.
