Hi,

Is there MIDI feedback loop by any chance? What can you see in the MIDI Monitor?

Hi
Problem was the TD-3 connected with USB and 5 din midi simultaneously. To test what you said i first switched on Moog and Cubase, there is no problem. Then i switched TD-3 and there is hanging note again. I realized problem dissapears if unplug the USB cable from TD-3
