Hi drdemirel,
Thank you for your message.
These are the steps to freely transfer your existing Cubasis LE 2 instrument and plug-in in-app purchases to Cubasis LE 3:
In addition, please note that Cubasis LE 2 and Cubasis LE 3 come with their dedicated Full Feature Set In-App Purchase, which is not transferrable.
From time to time the Cubasis apps and selected in-app purchases are offered on sale. Today, our Xmas sale ends. If you have plans to purchase the CB LE 3 Full Festure Set IAP, it might be still available at a reduced price.
Hope that helps!
Best wishes,
Lars
