Ah OK, that's what I thought you meant.  Of course, the main feature of the
System 700 sequencer in this respect is rotary switches that can change the
timing accurately on the fly.  A switch and a pulse divider might be easier
to work with.  This would also be true for the comparison to the SAM-16
sequencer that Gene mentioned; switching from 1/8th to 1/16th quickly and
accurately is tough with a continuous knob.

I guess no single step sequencer will ever have all of the features possible
but it is cool that each seem to have their own quirks and personality that
make them unique!
