I have been trying for an hour to synchronize 2 passes recorded from a 4 track Portastudio with stereo outs. I try to adjust the 2nd pair of tracks to the first 2 by stretching or squeezing parts which drift.
The tempo detector doesn’t work correctly even though there is a repetitive drum part with strong beats.
Then I try the beat calculator and start off OK matching for 4 measures. Then it starts to drift and I do some more measures, After a couple of times, it suddenly upsets all the previous work by resetting to the track start instead of the selection start, and I have to start all over.
There is no undo for this, as in previous versions of Cubase. These bar changes do not show in the history log. All I can do is save after every successful calculation and revert to save when it screws it all up. But it keeps screwing up so I can never finish.
