Mults of 16.  If you can fit two independent Superseque circuits onto one
board, you'd be designing a mother of a sequencer!  

I have a Superseque with 4 rows, all running from the same counter.
I often wish I could have two rows running in one mode (up/down) while the
other two do something different.  It would also be groovey if I could set
different sequence lengths for different rows.

Superslow to audio.  Some sort of math circuitry to give clock ratios
would be good too.

My hands!  {-;  CV-able clock is a must.  If you use a syncable vco you
get some really nice timing relationships between sequencers.  A CV sum
input so you can add CVs from a keyboard, other sequencer.

All designed into the superseque, maybe add a down mode.  Random would be
cool, but I don't know how you'd add that to the existing design.  CV to
step #, you could do that with a 4 BIT ADC switched to the input of the
4514.  CVable gate time.  Note skip.  PW on the clock, (with PWM?).

None.

At least two rows of 16.  Lots of CV outputs, you'll never have enough
once you start using one.  Inverted outputs, for mirror image patterns.

I'm hungry for more sequencers.  I recently did a session with five
analogue sequencers going all at once and pure magic came out of it.  No
one should have just one.  I think it's wonderful you're taking on this
project.  IF there's any way I can help out, just ask!
