Hi Yash,
Thank you for reaching out to the Microsoft Community. Regarding your question about whether the Serum music plugin is compatible with a Snapdragon X 12-core Windows Surface device running ARM64 with 16GB of RAM, I’ll do my best to assist you.
Before we move forward, could you please confirm the exact Surface model you're using? You can find this information by clicking the Start menu, typing System Information in the search bar, and selecting it from the results. If you're able to share a screenshot of that page, it would greatly help me verify your device’s compatibility.
Looking forward to your reply.
Warm regards,
Edward Schlobohm
