Ever since microsoft released it’s new midi 2.0 stuff in October 2025 I’ll get half way through a song, save it, then eventually the whole program freezes and is unresponsive. If i reopen renoise and then try to select any of the midi devices it instantly freezes again. I can restart the computer and select those midi devices and they work, but if I try to load any saved songs with those devices it instantly freezes up again and needs to reboot. so I have a bunch of half sequenced songs I cannot edit or pull note data from. I’m blaming microsoft, reason has the same results. damned OS making the whole computer useless again.
Oh and then anytime I close renoise it locks up and crashes too. awesome.
Have you already tried to deinstall and reinstall or update your MIDI drivers?
For me it sounds more like a problem with drivers. Not with Windows. If you just updated/upgraded to W11 from an older Windows (Win7/8) you probably need to update some drivers to make them W11 compatible.
No problems here with latest Windows 11. I can use all my MIDI devices without any issue.
