Sequential circuits samplers

After some fiddling last night I got everything to work the way I 
wanted to.  I didn't have to save the preset after making the change, 
but I did have to make sure I put it back into preset mode after 
making the changes.  Also, yes, you are absolutely correct about 
the "thru" switch: I had to toggle it back and forth a couple of 
times for it to finally let a signal flow though it. It's probably 
shorted so one of these days I'll replace it with a more robust one.

Thanks for your help!
