I see that nobody has replied. I cant think what is causing this, what host programme are you using to run the VI or are you running it stand-alone?
When a keyboard sends a midi signal there is a note-on instruction then a note-off instruction when you lift the key. It sounds to me that you are losing the note-off instruction. Does your keyboard have a way of controlling this ?
Is the keyboard set only to Local ?
I'm using the stand-alone version. Should i run the vi with something like Cubase to have more options ?
I don't have any way to control the note/off instructions. Moreover i think that every message can be lost, because some notes are note played.
It seems to be something like 1 message every second only, note on or note of (and 1 note only)...difficult for playing
The keyboard is not set only to local.
I only open 1 midi port, set to 1st port.
