Hi, the problem is most likely you are using outline around your song? In the right hand corner you will see (Wipe type: Set to txt) Below that you will see boxes marked outline (left, right, top, bottom). Set these values from 2 to all 0's.
Some people make the mistake of making a track and coloring the outline setting to the screen color. This does not eliminate the outline drawing from being done, you need to tell it physically to not draw the additional pixels and binary codes.
I am new here, so I will need to see if I can upload a picture. You can use their demo song "Devil Went Down To Georgia" and look at the settings. They removed the actual outline draw which is located above the shadow areas. When making fast tunes, these should be set to all 0's.
Binary in their program only draws so fast. I have a program that is way more complex over KBStudio or even MTU's Workstation. I have not done any author work in a long time, but can do rap and keep the outline. This works on a VERY old platform though that was out way before MTU's Workstation. Try what I have suggested and let me know
