No sound - AT ALL!!! [Solved]

[Franz]

the most important thing to do is not panick

I didn't know, so I failed this first step.

as its booting up hold down the lfo 'shape' button

The Rack Classic doesn't have such a button - it's a knob which cannot be pushed.

BUT the parameter left button does the trick and IT WORKS!!!

Thank you ever so much for leading me in the right direction to solve this HUGE problem (which causes people to panic)....
