1 TopicMIDI sysex message transmit fails after installing Security Update KB5077181
In the widely used MIDI application MIDI OX, I can no longer transmit MIDI sysex messages to a MIDI output port. Connecting a MIDI input in the app to a MIDI output echoes MIDI channel messages normally. Sysex messages do not appear in the output window and are not sent to the MIDI output port. Also, attempting to send a sysex message from within the app results in the error message "SysEx: No Buffers Available". I was able to repoduce this with two USB MIDI interfaces: M-Audio Midisport 4x4, and MOTU Midi Express 128. Uninstalling Security Update KB5077181 restores expected functionality. This is on Windows 11 Pro. LInk to my feedback hub report on this issue: https://aka.ms/AAzwx9y26Views0likes0Comments
