I transferred a two track 1/4" tape to WL. One track was going in the forward direction the other in the reverse direction.
My normal way of working is to reverse the track going in the reverse direction via the reverse command in WL and place it at the end of the normal track so everything is going in the right direction. I do this all the time in 9.5.5 but when I tried it in WL 10 it would not play. The cursor moved but no sound. I tried it three times and finally went back to 9.5.5 where it worked perfectly. FWIW.
Also sometimes WL 10 seems to shudder in playback for no apparent reason. It is like it is catching up with itself. Same sound card as I use for 9.5.5 but I never had that problem. Maybe something to do with latency???
