Hi,
We do think a tempo track is important and it will be part of an update in the future. We have a long feature request list and of course we would like to have all possible features inside Cubasis. But as we don’t have unlimited resources we have to go step by step prioritising the features and reacting quickly to new technologies (e.g. Audiobus, Inter-App Audio) that we didn’t have on scope. If we would have tried to put all thinkable features inside Cubasis starting from v.1.0 Cubasis would not be released yet and would be still in the making.
The good news is that 1.8 will include automation and this will lay the fundament for the tempo track.
