midi monitoring doesn't work

Hi,
Can you clarify this a litte bit for me please.
Are you referring to 'midi monitoring' inside Control Surface Studio?
Also, do you mean that if midi monitoring is turn on in CSS and you move a physical input on your controller, the midi message does not show up in the midi monitor menu?

Is the name of your controller displayed in the 'Connected MIDI Inputs' area of the midi monitoring area?

If it's picking that up then midi monitoring should be working.
With midi monitoring menu open and turned on, when you turn/press an input on your controller, do any values appear in the 'Latest MIDI Message received' section?
If they do then this tells us that midi monitoring is working correctly and the problem must be something else.

hmm very strange, if the name of the controller is appearing that it means it is detected and should receive midi data.
Do you have anything running in between which would be blocking the midi messages? software or hardware

Glad you got it sorted.
