I am aware that it is possible to use vari speed recording, like Pro Tools and Logic can do, in Studio One, by setting the file temp and using the time stretch setting. This allows one to even record difficult passages at a slower tempo, then type in the original tempo when you are done and everything works fine.
However I was disappointed to realize that this does not work in a session with multiple tempos, as there is no one "File tempo" to set. Most of my material does have tempo maps that vary throughout the song.
In both Pro Tools and Logic this is so simple, please consider a way to do this as there are so many times one needs to record a difficult string run, drum fill, piano break, or whatever, at a slower tempo then go back to normal speed.
Since Studio One does not have a locked tempo (conductor) track, like other DAWs, I hope this is not impossible.
