Hello,
I want to give my another gear some soundeffects(bit reducer,patch volume low high,filter....) from the arp to matrix section from the virus but it does only work with the LFO´s.Apparently the Arpegiator is not working.I try using the audition button but nothing.
by the way:I miss the Filter Saturation in the target page 
Hold down some keys?? 
The hole world is waiting for an answer.
I don't think I understand your question proper but if there is any solution, check the audio routing options in the virus.
I.It works with the internal signals but not with external gear?
How do you trigger the arp when using the internal oscs?
Which external audio mode are you using?
Static
Now let the groovebox play and press the audition button on the virus.Notthing,The Arp don´t change anything on the external sound.
By the way you can hear the external sound .You can also change the filter frequency and! you can use a lfo to modulate.That works.
Static mode is exactly what the name says: static (not changing). It disables the envelopes and doesn't require you to trigger a note...that's why the arp isn't working.
You should use Dynamic mode and then trigger some notes to get the arp working. When no note is triggered you won't be able to hear the external input.
RTFM 
damn it works:)
Will post a little demo soon
