Alternative to MIDI-CV

     Here at work we got a demo of a programmable analog array, about four 
     months ago. Of course I was right up front asking all the questions 
     (it's pretty amazing how many digital engineers do not grok analog 
     electronics AT ALL). Nothing really applicable to synth builders, I'm 
     afraid, these things are designed to receive a serial binary image 
     download on an input port which loads a bunch of registers telling the 
     array who connects to what and how much resistance to use in the 
     connections (as I remember). Not enough range or variability to make 
     filters or oscillators, maybe useful for modulation routing and 
     patching, but no fireworks went off for me during the demo. I thought, 
     "hmmm interesting, I'll wait and see what happens over the next year".
     The main application as I was told was for these things to be used in 
     mechanical systems control (like car engines etc.) to compensate for 
     wear over time or changes in operating conditions.
     If I see anything new and interesting along these lines I'll be sure 
     and post to the list.

Just curious Gene - have you used any programmable analog arrays?  If so, 
what's your impression?  Any utility to the SYNTH-DIY crowd?  I kinda lost 
track of things when my subscription to EE Times lapsed, and I'm wondering 
what the current state of the art is...
