Hello Vincent,
When you startup after crash I have to install the dongle of Cubase and
Arturia again, When the Jupiter is on the picture of the Arp2600 can
be gone and you can't save your last sound you made (it happend with the
miniMg as wel!) I have to realy shut of my computer (not restart) and
start it up to loose the sychrosoft warning from Cubase protection divice
not found. When I take the Jupiter out of the VSTrack most problems are
gone. Greatings David
