Hey Jamie,
 Unfortunately, it's not as simple as running MIDI through a signal 
processor/envelope follower to recover a clock signal. Basically, the MIDI 
Clock signal is digital information, and there are several words of info 
that have to be captured, interpreted, and turned into a "normal" clock 
signal that can drive a regular analog sequencer. It sounds like what you 
need is one of the "MIDI to sequencer interface" chips from Blacet
http://www.blacet.com/misc.html
 You feed the MIDI signal in, and you get clock pulses out. There are some 
good examples on the data sheet. Hopefully this will do the trick for you. 
It's about $16, and that's pretty cheap considering how much of the 'digital 
housekeeping' it does for you.
