Doepfer

My comments regarding end of cycle outs and unconditional attacks on 
the 143-1 did not generate very much enthusiasm.  However, if the EG 
already has a cycling option, it seems like the end of cycle trigger 
might already be there.  How about a patch point on the board for 
those of us who would be willing to drill a hole and solder to it?  
And, maybe a jumper for unconditional attacks? (Is this a lot 
harder?)  

Just a suggestion. Like I said, I would definitely buy the module if 
it came out as currently planned.
