True, both Cubasis and Cubase are products by Steinberg, and they even share import/exchange functions.
But as a Cubasis and Cubase user, I consider both as completely different products!
I have this Roland VS-2480 hooked up via ADAT to a PC with Cubase Artist 7.5 as a permanent setup. Along with a collection of vintage music gear, I use a Novation Impulse 49 as an extra control surface.
I can assure you that the cables alone will disqualify to be called a mobile setup!
On the other hand, Cubasis and this wagonload of iPad apps give me the freedom to work anywhere. I use a PreSonus AudioBox iTwo when recording audio or a Korg nanoKEY Studio when playing and recording some synths.
Cubasis is perfect for sketching and recording audio samples to prepare them to be used in other apps.
So with my mobile setup, I love to work with my nanoKEY Studio and I’m considering to get the nanoKONTROL Studio too. Unfortunately Cubasis 2.0 offers no support for these amazing Bluetooth LE tools other than the keys.
At the moment I’m using Korg Gadget a lot for it is great fun to play with these well integrated products.
So, I guess that aspirant Cubasis users will just choose between the available iPad/iPhone DAW’s. And it’s up to Steinberg to bring new users a competitive product.
