I'm looking for a solution to an 'automation' problem... I have a few 0...5V control voltages (eight of them in fact) and a few switch closures (four of them) which I need to automate.

-Is there a general-purpose 8-in/8-out 0-5V "analog to MIDi and MIDI back to analog" board anywhere out there?

I'm looking to store (and later replay) the 0-5V voltages.

MIDI just seems like the most flexible thing to store, replay and -if needs be- manipulate in a computer as data/lines to 'shape' offline, or punch-in and overwrite, online.

Mabye Doepfer have some cards that may fit your needs. USB 64 to convert voltage to MIDI, (or pocket electronic) and MTV 16 to convert midi to voltage.

look under products.
two cents...

"The BS1USB is a handy little device is perfect for adding a user-definable function to your PC. For example, with a few lines of code and a little hardware, you can create a data logger that runs remotely, then uploads data to your PC each time it is reconnected. Headers provide easy access to all 8 I/O pins, power, and ground."

don't know if a uController package like this would work--it is not midi.(I've programmed 1 to spit Midi, but to eat midi is too involved for this)

Input..... 24 to be in fact

Output.... lots of options

So what in disneynation would you ever need to automate?
 
This handles 24 MIDI to trigger 5v logic. The code is there as well. There's more at that site.
You could mod it to give you 12 in and 12 out.

I made a 24 midi input device a while ago, using arduino and stuff like multiplexers/demultiplexers, shift registers (for lcd), etc.
I can send you all the instructions, code if interested.
 
sorry if this has already been mentioned around here

look for the forum and the wiki

PCBs and parts and thingys

I have purchased but been too slack to finish a project

Yes, www.ucapps.de is the source for DIY Midi projects!  Excellent stuff.

Here's my MIDI Controller (built on a cardboard, circa 2005): http://www.fivefish.net/diy/MidiLC/
