Received this morning from Aruria:Hi,
When running in demo mode, it's normal that not all the keys work, they will work if the software is activated.
The intermittent volume issue can be caused by different facts that I deny so far, but I will suggest to make sure you have updated your Asio4All drivers. Analog Lab or any of our instruments can be used virtually or you can use them with a universal Midi Controller which makes the task easier and more user-friendly (helps with the workflow)
I stay at your disposal if any further assistance is needed.
Best regards,
Amin
