Does Cubasis serve is primary purpose? Yes. Are there things it does better than Logic and Zenbeats? Yes. Do Logic and zenbeats offer different features exclusive and respective of each other in relation to Cubasis ? Yes.
Is it annoying to feel like you’re repurchasing software? Yes.
I’ll just say this in Cubasis defense: they are a miniature portion of Steinbergs focus (especially when compared to the Professional desktop cubase/nuendo suite ) and they came a long way in 5 years.
With that said, Cubasis and all IAP without a sale price aren’t cheap , so I hear what you’re saying - with that said, I think that’s why iPad and iOS deserve a professional DAW and that short list is all it would take as I and many others agree.
MIDI learn
PDC
Time sig/tempo track update
Better file management for comp recording/file system
Audio/midi routing
Multiple interface selection
(And the latest but often requested feature is something like a drum editor /maybe even groove agent se port)^ but some kind of better drum editing and design
But yes: I wish if you owned cubase pro it was included because I also bought Cubasis because i bought cubase pro 10.5 along with a lot of GA stuff and add on packs
