Hi there
I’m sorry too hear you are having trouble.
The Aeros does not support deletion of tracks, this is for various reasons but this is not really a blocker, you can get the same behavior as deleting by undoing and re-recording a track. You can find more information about why we don’t allow track deletion and add any further input here.
If you would like to improve the undoing mechanism, we have a feature called “Cancel Recording” which makes it so that you can cancel (immediately undo) the current recording or overdub with one tap of the Play / Stop All button, you can enable this setting in the Device settings, it is off by default.
The Aeros does not create copies of the project, no. The Aeros will only save the current project to the chosen location. To be frank, it does not seem logical to expect a file to be automatically copied from the SD to the internal, but that being said it definitely should be possible to create copies of songs on the Aeros itself. We do plan on allowing this soon in a future firmware update.
Did you try to reimport the tracks into the Aeros after using them in logic? This is not supported, but import support is coming soon.
Let me know if you have any more questions and feel free to write to support@singularsound.com with any other concerns.
We appreciate your patience and thank you for reporting.
