[DIY] Seq. 2 - Update!!

[tomg]

It's gonna work! Not exactly like I drew it but yeah! You are going to be able
to set this up like you want it. 8/16/24 static/programmable/linked glide/no glide
leds, pots/switches...etc. whatever you like. You can spend as much money on it 
as you have!!!

OTOH it can be set up very simply and cheap. I think I can do the board somewhere
 in the $15-25 dollar range......we'll see. I still have a few little things to work out
but it's gonna work..... I did some IC reduction from 24 to 14. I hope to remove more 
but I might have to add a few, I don't know for sure yet. Most are CMOS and in
the $0.50 range. So chips and board maybe $25-35. 

BE WARNED!!! If carried to the extreme you could sink $250.00 dollars in this thing.
And YES! You can link as many as you want, like the Seq1. 

For those who asked what the trigger out does. I should have called it carry-out.
It starts the next Seq2 or Seq1 module. From what I can see now there should
be no problem mixing the two.
