Microsoft has unveiled Windows 11 Insider Preview Build 27788, introducing exciting features like the public preview of Windows MIDI Services, a significant upgrade for musicians. This build enhances MIDI capabilities, supports seamless OneDrive file resumption across devices, and includes various improvements and fixes for a smoother user experience.

Windows 11 Insider Preview Build 27788: What’s New?
Exciting news for Windows Insiders! The latest Insider Preview Build 27788 is now available in the Canary Channel. This build brings significant updates, especially for music creators and productivity enthusiasts.
Major Updates: Windows MIDI Services Public Preview
One of the standout features in Build 27788 is the introduction of Windows MIDI Services. This is a complete rewrite of MIDI on Windows, aimed at enhancing the experience for musicians. As Amanda Langowski notes, “MIDI is essential to making music and was heavily used in the rise of hip-hop and other genres.”
MIDI 0 is a game-changer, offering increased speed, fidelity, and better control over instruments. The new Windows MIDI Services stack supports both MIDI 0 and 0, ensuring compatibility and modern functionality. Key benefits include:
- Full support for MIDI 0 standards, including high-speed data transmission.
- Multi-client support, allowing multiple apps to use a device simultaneously.
- Built-in loopback and app-to-app MIDI capabilities.
Seamless OneDrive Integration
Another notable feature is the ability to seamlessly resume OneDrive files from your phone to your PC. This feature allows users to pick up where they left off editing documents with just one click. It works with various file types, including Word, Excel, and PDFs. However, remember that:
- You must sign in with a Microsoft account.
- The OneDrive file must be opened on your phone before unlocking your PC.
What’s Important to Know
For those using File Explorer, there are also some useful changes. The system now restores all previously open tabs when logging back in. Additionally, users can snooze or turn off backup reminders directly from the address bar.
As always, Microsoft encourages feedback. Insiders can file their thoughts in the Feedback Hub under Devices and Drivers.
“We look forward to having Windows Insiders who dabble in music creation try out the Windows MIDI Services Public Preview.”
This build is a step forward for both musicians and productivity users. Dive in, explore the new features, and let Microsoft know what you think!
