Fixing the random module

This Random module, with its noise generators and sample&hold, is one of the first modules I made in 2017.  It's based on a design by Yves Usson for his Yusynth.

For some time, I had been under the impression that the output of the sample&hold had no influence on the modulations I assigned it to.

After some investigation, it appears that the input jack is at fault.  This jack has a switch so that if no plug is connected then the internal noise feeds the sample&hold. When a plug is connected, it opens the switch and the input signal feeds the sample&hold function.
 
In this case, the jack is of bad quality and its switch no longer closes properly.
 

Access is not so easy

Once replaced, everything works again.
I even changed the clock input jack because I thought we were using the same internal/external function management principle. But it wasn't necessary: the switch is outside.

Fixed !
