DIY box for adding shuffle to a Sync Signal

[Fraser, Colin J]

Definately a job for a PIC...

If you only need 16th notes to shuffle, you could do it by running through a
12 clock pulse sequence that drops some pulses from the first set of 6, and
adds double pulses to the second set to get back to 12 output pulses.
Reset the count of 12 when RUN/STOP goes high to keep the shuffle position
correct.

eg...
shuffle of 1 (ie second 16th note is 1 clock pulse late)

input pulse:   1  2  3  4  5  6  7  8  9 10 11 12
output pulse:  *  *  *  *  *     *  *  *  *  * ** 
16th note:     *                    *
                                    ^ 2nd note late - groovy !

It doesn't matter that the pulse lengths are not regular if you are only
triggering every 6 pulses.
Need to do this for my 606 & 303 sometime...
