Weird problem. When i record a mix, the .wav file is complete and contains my whole audio mix. However when i export the clip, it's not complete. I recorded 2 video mixes of 30 mins each and got 15mins and 5 mins export :(. I was so upset i did 1 hour session for nothing. Is it a known bug ? I'm using SSL 2.7 on Macbook air i7 8go ram 512 ssd and recording on external Corsair voyager GS USB 3.0 drive (150 mo/s write)
