AW: [Doepfer_a100] A-155 - how to start on first step after reset?

The problem has been solved with the A-154 as controller for the A-155. A
reset "prepares" the internal logic for the "real" reset. The advance to
step 1 takes place at the next clock pulse. But we already got some
complaints about this behaviour as the people are used to the behaviour
where a reset causes an immediate jump to step 1.

Best wishes
