Hi, I dragged an mp3 vocal file into the standalone trial program and then used the conversion function. No problem so far. The entire song was converted and the first 4 sentences are as good as perfect. But from the 5th sentence onwards, the waveform no longer appears. If I click on a note to edit the text, the program crashes completely. Why is that? Is this possibly a limitation of the test version? If not, how can I solve the problem?
