Frequency dividers

[Mitchell Hudson]

    To tell the truth I am not sure what musical intervals I was trying to get.
Most often I end up using the frequency divider as a clock and or CV.
    I was thinking to generate /4 by dividing the /2 by 2 and /6 by dividing
the /3 by 2. i figured to use one 4013. I have two more knobs to play with so
these could be any intervals I like. I thought if I could figure out the /1.5 I
could use that to divide the /3 output to get /4.5. Then I still have one more
knob to work with which could be anything.
