Hi Bobby,
Thanks for your message.
Cubasis LE can be unlocked from demo mode via a huge list of supported hardware devices from Yamaha, Steinberg, Line 6 and many 3rd party manufacturers: What Is Cubasis LE | Steinberg
Unfortunately, the Roland device can not be used to unlock Cubasis LE from demo mode as of yet.
In regards to the regular Cubasis app version:
Please get in touch with Roland to ask them, if they’ve tested the device with Cubasis.
If required, I’m able to have them equipped with a promo code for testing purposes.
Hope that helps.
Best,
Lars
