I would like to see if some people can replicate a editing Problem I'm having with Sonar Platinum, windows 10.
 
split an audio clip into 4 seperate clips.
right click and lasso/highlight the 4 clips
go to process, apply effect, gain 3db boost
Hit play or spacebar - does it play or hang?
 
Thanks any help would be great thanks. Arthur 

Put the time line right before the clip and hit play, I get a constant hang.  

Not a problem here; must be more to it. Can you replicate the problem in a new project started from SONAR's default Normal template? Is it an ordinary audio clip that you recorded or an imported loop or...?

Following what you said, it seems to work fine for me.  I did notice an odd thing in doing it, though:  I could not seem to select the fourth split of the clip by holding shift and clicking on the fourth portion, while I could select 1, 2 and 3 that way. 

As to that last, the fourth could be selected by shift-click BEYOND the actual clip ... probably not relevant to your problem.
 

thanks, so far. can some one try with grafics on the motherboard with win 10 sonar platinum. Arthur
