File exchange between Cubasis and supported hard drives is handled via the “Open in/Open with” iOS function.
Please check with the manufacturer if the PQI Air Pen device supports this function and how to enable it (e.g. SanDisk drives require to install and launch the corresponding iOS sync app).
Exporting files to external hard drives is explained in the MediaBay chapter of Cubasis’ in-app help.
“Open in/Open with” support has to be provided/enabled by the hard drive / wireless drive manufacturer.
While Cubasis can be installed on iOS 7.1.4 we recommend to use it with the latest available iOS version.
Some of the features (e.g. Audio Unit) require iOS 9, and it is likely that other functions might not perform as expected with older iOS versions.
It seems there is no support for IO Dock 2 in the current Cubasis version - so I was wondering if it is in plans? It hasn’t been that long ago that I bought it and would have eagerly used Cubasis. Somehow doing some web searches I got the picture that Cubasis was compatible with IO Dock 2 sometime earlier - am I right? Thanks!
