My virus has a split personality

[Jade]

I'm starting to get really afraid of my indigo II .

After startup it works fine for a time, but then it can cut off all notes playing, turning them to a beep or a loud noise... it's like it gets a hang up, 'cause I have to restart it. It really frightens me, but I'm not sure if I'm pushing it too hard by playing too many notes at a time or if it's defective. It happens all the time in multi-mode, but only sometimes in single-mode. It just doesn't seem like a normal behavior, even if you have panic-buttons on the panel.

So what should I do about it?
