[NM] Problem with NM1 and Cubase

[Ole]

Hi,
(my first message to the list).

I've bought a NM Classic and created a patch that I am controlling from 
Cubase. Everything works well recording in Cubase and replaying through 
Cubase untill I press "Stop" after that my NM turns several octaves down in 
pitch ! It will only play properly after I turn the synth off and back on 
again. However, the same thing happens when I hit "stop" in my sequencer and 
try to play again.  Do anyone have a clue to what might be wrong in my 
setup?

best regards
ole
