Re: MORE INFO FROM DOEPFER ABOUT THE NEW SEQ CONTROLLER !!!

2002-11-06 by (i think you can figure that out)

I don't know if this is too late (suggestions on the new 
sequencer), but  all of the dirfectional control could be handled if 
they elected to include an ANALOG VC INPUT.

What this would do it convert an analog voltage into digital, and 
use those numbers to override the count on the sequencer at a 
given time.  Sound impossible?  It ain't - I've got a working 
prototype of my own at home.  I used an ADC 0804 chip, which 
converts the incoming control voltage into four bit binary, and 
those numbers go into the counter presets and BANG - you can 
totally control the direction of travel based on the amount of 
voltage at that pin at a given time.  Ground = step 1, +8 = step 
sixteen.

Want it to do pendulum?  Insert a triangle wave with a 0 to 8 volt 
swing.  Want random?  Put  noise in the input.  Want a sequence 
just between stages 6 and 12?  Just narrow the amplitude of the 
input..

Also, you can put a 1/voct keyboard into it and slave the 
sequencer to advance to any step at the touch of a key.  This is 
really handy.

It's a nice way of doing directional control because you can 
control all these things externally, ao you can tunr them off/on or 
change this at will when you want via voltage automation.

just me two cents.

best,

Peter
