Hi Jean-Paul: after you set the ranges for the selected measures, make sure that the loop has not come on and reset itself to the default setting of 1. To check, hold down the hot-key which tells whether it is on or off, if It is on then turn it off by pressing the letter L twice quickly.. If you have already tried this, disregard this. e-mail.

But it's shorter than 4 measures tempo 120: 1 or 2%. I select the four measures. An after: length, audio checked, start time not checked. But after processing the four measures are empty, I don't hear anything. It's possible I forget something, but I don't find what. Thank you for your help Jean-Paul
