We have identified several issues that occur when using Cubasis with Apple’s latest iPad Pro 11" and 12.9" 2018 models.
In certain situations, the CPU usage of the new iPad Pro 2018 devices might be higher compared to previous iPad Pro models.
Also, using Inter-App Audio and/or Audio Unit plug-ins can lead to several issues on these new iPad Pro devices.
From what we have observed, the problems seem to be valid for several third party instruments and effects apps as well, and occur same way when launching these apps in stand-alone mode.
Our engineering has started to evaluate these issues, and we hope being able to solve the problem as soon as possible.
