Dimension Pro Patch 08/Guitars/Almost Together
Once I hit record Sonar Locks and Freezes
Just want to know if its only happening to me?

Thanks for mentioning the program. This has been reported before. The problem is caused by the Random Unipolar settings in the MIDI Matrix. The only fix I know is changing the Depth from 40 to 0.
 
The MIDI matrix is accessed by clicking the third icon to the right of the program name in the DPro UI.
