SuperSeque

[David Halliday (Volt Computer)]

How about http://www.paia.com/ek7.htm

This is a very clever 4-bit flash converter.  
The text says that it is good to 1KHz or so.  
I bet with more modern comparitors, you could get this up quite a bit
higher.

I'm in the planning stages for a sequencer based loosely on
the Superseque. My first planned addition is voltage controlled
stage select exclusive-or'ed with the clock stage select. This
allows you to select any order of stages. For example, when
the output of the 4 bit ADC is 0x0F (1111), the clock output will
count thru the stages from 16 to 1:

Clock  ADC    Xor
0000   1111  1111   
0001   1111  1110
0010   1111  1101

etc.

Every possible order of stages can be selected with the VC stage
select input. I haven't found a good (cheap and fast) ADC yet.
I would like to find something that would work in the audio 
range. Anyone have any suggestions?
