Analog track transfer to midi track problem

There is a problem with the analog to midi conversion with this last update. In the prior versions, I was able to grab a analog track and place it on a midi track and Melodyne would convert the analog track to midi. With this version of Platinum, it will convert the track 1/2 the way and freeze the program. I have increased the asio buffers to 1024, made shorter clips, and removed the vst from the track. Your wealth of knowledge is much welcomed and appreciated! Thanks in advance!
