Hi all, 

Here comes a question regarding a strange muting behaviour of my A-151 Sequential switch. 

I have a Precision adder (A-185-2), a Sequential switch (A-151) and two A-110's set up in the top row of an 9HE low cost case. 

The CV output of one row of an MAQ 16/3 sequencer is connected to one of the inputs of the Precision adder (switch in "+" mode"). CV values from the MAQ are the distributed by the A-185-2 to both oscillators through the system bus. 

I would then like to offset the sequence from the MAQ by using the Sequential switch and connect it into another of the Precison adders inputs. 

But when I connect the O/I of the Sequential switch into another input of the Precision adder (switch in "+" mode"), and when there is no input to the Sequential switch (nothing plugged in into I/O 1 through 4), the oscillators go mute! The sound disappears completely. 

No CV -> A-151 -> A-185-2 -> System bus = mutes A-110 = no sound!

Could someone explain what is going on?

Thanks, 
Jacob
