Probably the easiest way to do it would be to get a blacet MIDI to Sequencer
Interface Chip - http://www.blacet.com/misc.html
That gives you a 24ppqn pulse. Divide that by 24 and you have a one pulse per quarter note signal (that is what you are describing right?) To get that you could use 2 4017's (div by 6 then div by 4). http://www.doctronics.co.uk/images/4017_07.gif
There are probably more elegant ways to pull this off, but you get the idea.
