Hi @arkadiusz_dec,
A warm welcome to the Cubasis forum and sorry for my late reply due to holidays.,
Do yo use Cubasis for iOS or Android?
Please check out the “Adding Audio tracks” chapter of our “Getting started with Cubasis” tutorial which hopefully helps to resolve your recording issue:
In addition, please check out our dedicated Cubasis Importer article to learn more about its features and limitations: About the Cubasis Importer
Hope that helps!
Stay safe,
Lars
