Many years ago, I had designed a "nanosequencer" that was a 1 X 4
combination CV-step and gate sequencer that fit nicely in a 2U
module. The idea was instead of one large expensive sequencer, any
number of nanosequencers could be stacked together, either
horizontally or vertically. So if you had four of them, then you
could patch them together to make a 1 X 16, 2 X 8, or 4 X 4 sequencer,
or two 1 X 8 sequencers, or one 2 X 4 sequencer and two 1 X 4
sequencers, etc. I had a working prototype built around a small
handful of discrete CMOS. It was simple and inexpensive. Larry and
I had worked out a 2U expander module that added 2 more CV channels
and another row of gates. Moe had drawn up a number of different
Stooge panels. Many people thought that it was a very clever and
innovative design. So I had thought about doing a run of PCB's, but
right around the same time Paul announced the 600, and it was decided
that introducing a possibly competing sequencer in MOTM format was a
bad idea.

I totally agree with that, although parallel input isn't that much of
a tactical advantage when using a step sequencer.

Even ignoring price, imho, it can beat any hardware sequencer out
there as a compositional tool. Although, I have not tried using a
CV-to-MIDI converter to see if I can select steps with a control
voltage. That is one function that would be easier with a voltage
sequencer.

Numerology does have a fader box module. Although I have never tried
it even though I have a Peavey PC1600x.
