I'm using the trial version of sound forge 12.
Does it have 4 channel, or 2 stereo channels one on top one on bottom for inserting a fix.
Very common and it on a master would be to replace one bar or sometimes one note.
On more than several occasions I will give the client a pre-master to go home with.
I would have the entire CD laid out P and Q codes 99 1/2% finished the need to replace a very small section without disturbing
any of the other work.
In the old Sony CD architect I was able to do that
I'm confused about your 32 channel layout?
