Hey Everyone,

I'm trying to slowly raise the Filter cutoff on my 420 using the 
auxiliary output on my Pro 2000 going into the 1v/oct or FM2 jack on 
my 420(I have an 800 going into the FM1 jack).  However, when the 
kenton receives the midi message to raise the filter a little bit, I 
hear a pop sound.  Is this normal? I'm not sure if I need to use 
another 800 to smooth out each little progressive raising of the 
filter or if I don't have the kenton  set up properly. 

Any ideas?

Thanks,
-Matt
