As an advanced-ish amateur DAW user, and a Sonar Refugee now with about 30 hours of Mixcraft under my belt, I'm really enoying the transition; in fact many things are so much easier in Mixcraft, which on my setup it is far more robust / less "flakey" than Sonar. I'm seeing that there is nothing at all "adolescent" about Mixcraft; it's just really easy to use, and not as well-known. I think spec-wise it holds its own quite well against Sonar with respect to the things which matter most (to me anyway).
So, I'd like to see Acoustica do well. The Cakewalk exodus is maybe a unique opportunity (as I'm sure management already knows) to grow the customer base.
Hence some uncolicited advice to management: please consider emulating Presonus' approach in directly courting Sonar users -- not just through cross grade pricing, but also, by putting together some quick-start material aimed directly at them.
Excellent examples from Presonus range from the modest but very thoughtful "Basic Differences to Help You Get Started" post found here (it's the third post, 30 November 2017 by jpetit; it also serves as a way to quickly show a Sonar user that indeed, many beloved features exist in the target product)https://forums.presonus.com/viewtopic.php?f=151&t=27570
to the more time-consuming investment of these videos:https://www.youtube.com/playlist?list=P
To be done effectively, a Sonar expert needs to be engaged (if you don't already have someone in-house). (I'm not expert enough for the job unfortunately).
My 2 cents anyway.
