Divider Question

[Christopher List]

I want a circuit which takes a pulse input and does the following division...
 

Input:
   __    __    __    __    __    __    __
__|  |__|  |__|  |__|  |__|  |__|  |__|  |__


Output, div. by 2,3,4,5,6
   _____       _____       _____       _____
__|     |_____|     |_____|     |_____|

   ________          ________          _____
__|        |________|        |________|

   ___________             ___________           
__|           |___________|           |_____

   ______________                 __________
__|              |_______________|           

   _________________                   _____
__|                 |_________________|     


I would like to get simultaneous outputs. Notice that the duty cycle of the 
output pulses is in line with the input, so this is not just "clock division" 
in terms of skipping "X" pulses.

I just wanted some advice from you more experienced chaps on what approach I 
should take in terms of elegance and simplicity. Should I build it up from 
discrete flip-flops? This is easy for the 2 and 4, but I'd need to work out the 
logic for the other divisions. Is there a 4000B series IC that I haven't found 
that'd be easier? Maybe a hybrid, flip-flops for the Div2, Div4, and Div6 and 
"4xxx" chips (4018?) for the Div3 and Div5?

- Thanks,
Chris


ps
I got my 16 stage sequencer all put together this weekend. Still have to finish 
up a couple of the features, but it is so much fun! I've only got 2 channels of 
knobs, so I've started planning a piggyback module of 3 more channels that'll 
run off of the same clock data bus. It's got up/down (switch or CV), reset, 
hold (high CV locks everything, including reset),  program select by button or 
CV (gotta build that A/D converter this week), Each channel can be switched 
between 0/-5v and -5/+5v range, a row of LED's and a row of switches for gate 
and trigger outs... After running it at audio frequency over 8 steps and making 
kooky old-videogame sounding waveforms I understand why you want to have VCO's 
that go up to 50 or 100kHz...
