Cubasis 2.2 memory monster!

I run cubasis 2.1 on my iPad Air 2 16gb for quiet a while.
Yesterday updated to 2.2. Yes it’s a great update and I love it.
But after playing music even without recording,I noticed that the app is consuming the tablet memory.
from 1 go to 3.3 go in 2 houers without mixing down.
What’s going on here???

Hi P2c,

We did not experience any problems in this regard so far.
Please provide us with an exact step by step description regarding the issue.

Could the issue be related to other instruments or iOS and does it help to restart Cubasis?

Thanks,
Lars

What should be the approximate total memory capacity of the cubasis 2.2 after upgrading from 2.1 if there are no mixdown sessions at all?
