Hi Dave,
At the moment I can only say that the 1.8 update will be the long awaited automation feature-set.
Our product strategy is to keep the updates coming to satisfy the needs of our user base while setting the bar of mobile music making higher with each update.
We do have a plan (based on user requests) but that plan is flexible to be able to react to new technologies (Audiobus, Inter-App Audio, etc.) or user-reported problems.
