Probably you hit a hot item here (my breath almost gets out of control 
;)) for a lot of people who stepped into this list during the last 
months, looking for DIY-synth-projects and then discovered the most 
projects discussed are in the analogue domain.
Sometimes I wonder if it would't be better to have a splitting up in
ADIY and DDIY. But from correspondence with some enthousiast analogue 
stuff DIY's I get the feeling they're not afraid of digital
stuff as well. As long as that stays this way and the analogue-minded
folks don't get irritated by digital items, personally I would prefer to 
keep it just as it is: One list.

about your programmer idea:
in the first place desinging a controller-device wouldn't be the hardest 
part I think, but after that you must have a midi-input to fed your 
synth. In the most cases this would imediately mean that you have to 
build a merger also. And that's different cake as far as I know.

But the general idea is something that's keeping my mind busy for a long 
time.
The way to build these kind of things in general however is programming 
eproms or things like that. And most of the time some A/D and or D/A 
conversion will be needed.
I realy would be glad to find some place on the internet where diy-sets 
are offered with preprogrammed modules for things like you are proposing 
in your message, and all other kind of stuff you can find in boxes made 
by philip rees, anatek and so on.

Otherwise:
can someone tell me about the most straight forward and affordable set of 
tools on the market to make these eproms by yourself? (as far as i'm 
concerned, using a pc in programming-process is not a problem).

This I don't understand. Talking about sysex?

Not to  me.
