Hi marshMellow,
Unfortunately the sample rate limitation comes from the iPad, we just provide the available rates.
So there is not much we can do about it.
Could you please give it a try to connect a headphone or audio interface to the iPad.
Once done, the iPad offers additional sample rates. Therefore it should be possible to switch the project rate down to 44.1 kHz.
Does this help to solve the problem?
Best wishes,
Lars
