Mixcraft won't start or freezes after a Windows 11 update

Microsoft has released updates for Windows 11 that cause some old USB MIDI or audio/MIDI devices to hang Mixcraft.   The updates add support for enhanced MIDI 1.0 to Windows 11 and pave the way for MIDI 2.0.  (February and March 2026.)  

Here are some things to try: 

1. Try opening Mixcraft using its icon to make sure you're not opening a project with a plugin problem.

2.  See if the problem is just setting-related by running the file called "Reset Audio To Factory Defaults" that is in your Acoustica Mixcraft 10 program files folder:

4. Try disconnecting all your USB MIDI or audio/MIDI devices and see if Mixcraft starts.

We've seen this problem with Avid MBox, Midiman, and a few others.  We'll be implementing a fix in Mixcraft 11. 

Here's a Microsoft page with some of the problems people have run into, along with possible workarounds:
