Hi,

Thanks for all the great suggestions. The prices are all much higher  
than I would pay, however.

If I bought a PIC programmer I could make one of these:

http://tomscarff.tripod.com/midi_24op/midi_to_24_outputs.htm

and build one of these for it:

http://tomscarff.tripod.com/relay/midi_relay_units.htm

A PIC progammer is pretty cheap, say $30 all the components to build  
the midi stuff from Mouser or Digikey probably wouldn't exceed $20-30.  
say I build it all on a punchboard with jumper wires,

So, i am comparing the doepfer solution at about $150 to the DIY  
solution at $60 or so. AND when it is all over I have a PIC programmer  
and can make any open source PIC project...

I was mainly hoping to find someone selling a similarly priced kit but  
where the circuit board was already made and they sold preprogrammed  
PIC's to save me the hassle of programming the PIC, and punchboarding  
or etching my own PC board. If there are enough lines it might make  
sense to do a layout and etch.

Anyway, that is kind of how I was looking at it. Save some hassle for  
a bit of extra money. Its not that big of a hassle where I would pay  
double though.

thanks,

Steve
