Hi agaland,
Thank you for your message.
As you might imagine we receive many feature requests for Cubasis.
Cubasis is made by a fairly small team, so we always have to plan feature scopes carefully, in order to keep up with regular updates.
As of yet, Cubasis has seen 30+ regular free updates with many new user-requested feature additions: New in Cubasis 3: A Brand-New Cubasis | Steinberg
As mentioned before tempo/signature track support remains on our list.
As of yet, I have no date, when the feature will be released.
Best,
Lars
