[sdiy] I finally did some SDIY this weekend

[James Patchell]

No, not stupid at all...it is all un committed logic.  When you turn the 
power on, it won't do anything...you will have to patch the module together 
to get what ever it is you want.  The first module will mostly be used to 
generate patterns (the one I mentioned).  The second module will have 8 
banks of 8 pots each, and a little logic to go along with it...which will 
be more familiar as it is more like your normal sequencer.  The final 
module will be a "memory" module, it will have a 16x8 array of toggle 
switchs to generate patterns with, as well as a pair of 2048x8 ram modules 
for doing basically the same thing (you will be able to load the ram 
modules via a midi port).

I have been working on this system for about four years now...and finally, 
things are starting to come together.
