Yup -- sorry, I phrased it badly.  When you clock from an external VCLFO you
can modulate the frequency of said VCLFO with the CV out from one of the
sequencer rows and thus modulate the duration of any given step.  For
example, in theory if the CVs in the row were

0v | 1v | 1v | 0v | 1v | 1v | 0v | 1v | 1v | 0v | 1v | 1v

the rhtymn of the output would be

1/4 | 1/8 | 1/8 | 1/4 | 1/8 | 1/8 | 1/4 | 1/8 | 1/8 | 1/4 | 1/8 | 1/8.

An octave is a doubling of frequency and you're working 1v/oct.  If the
clock goes twice as fast, the duration of the step is 1/2 as long.  Etc.

OK, I don't think I parsed that.  Are you saying that you can use the CVs
from a row to modulate the clock rate and thereby achieve the timing changes
that are possible with the per step switches?  Please elaborate.
