Hi,
below are some answers to your questions.
Limited by Apple, it is only possible to use once instance of an app.
However the included instruments in Cubasis (Micrologue, Microsonic) can be used for various tracks. Following your example, 2 MIDI tracks in Cubasis can be played back with different Micrologue instruments at once. Please consider that several instances of Micrologue can easily put some weight on the processor (track freeze can be of help if required).
The rec mode settings are independent from the click mode, therefore it is not possible to set click during pre-roll only in Cubasis.
As of now Takes/Lanes are not supported with Cubasis.
Audio recordings are saved with the project you’re working on.
Simply double tap on an audio event to open it in the audio editor and choose “Save to Media” to save audio recordings or other material permanently. Saved files will then appear in the “My audio files” folder (MediaBay/Audio) and can be easily used in other projects etc. When sharing/exporting projects all corresponding audio files will always be automaically included.
Best,
Lars
