Yeah, I can't use the NR as a master unless I buy something that
produced MIDI and DIN sync from the NR Clock Out.  The mod would *have*
to be cheaper than that...

Your idea of having the Ext Rate In be a *divider* would be teets on the
duck's back!

I like to have everything (808, BZone, Fat Controller, Mobius, PSIM, 
EGs, etc) ticking away in synchronized alien machine beats, and it 
would be cool to use the Noise Ring as a modulator.  Maybe a switch 
that disables the VCO and the CLOCK OUT becomes a Clock In?

I, too, often use one clock to sync everything in the system. One 
solution is to use the Noise Ring as the "master" clock, but there 
obviously are situations in which it is preferable to have another 
source generate this signal.

IIRC in response to an earlier post on the proposed Clock In, Grant 
had indicated he would investigate this possibility, but I don't 
think he ever posted the results... perhaps he will weigh in now?

My original thought was to add a switch so that the EXT RATE CV IN 
becomes a Clock In. But your suggestion has given me an even better 
idea: could flipping this switch convert the CLOCK OUT to a Clock In 
*and* also allow the EXT RATE pot and EXT RATE IN to control a clock 
divider for the pulse signal arriving at the Clock In jack?

This would be *very* special.

Hi Andrew
    (of the PSIM list fame) doc here...
    As far as i can see, the 1200 series modules were designed very
'close to the bone' everything is designed to make ultra-efficient use
of the components. and keep production cost & labor down to a minimum
So i think the chances that Grant will add features on production
boards or mod them significantly are slim to none.
    but (acknowledging the tedium of my devotion to DIY) if you are
handy with a soldering iron there are some opportunities on the
surface mount PCB though... 
    for an external clock input, you could interrupt the trace from
pin 7 of the TL074 (there's only one Tl074 on the board)and inject any
15-volt pulse signal into the NON-pin7 side of the cut. This exploits
the diode and 1/3 voltage-divider that Grant put on the board but a
better solution would be to build your own comparator and buffer with
a 15-volt output and inject it. That way you could control the
threshold for the trigger point of your incoming pulses or even sync 
directly to an external LFO.
     As for somehow re-fitting the internal clock controls as some
kind of divider. I think that would be impractically laborious &
costly if not nigh on impossible. But adding Any common CMOS single
divider chip (ie 4022 or 4017) in front of the aforementioned
interrupt would do the trick. John Blacet sells a dandy Binary divider
that could be used externally too.

     If you're skittish about hacking a surface-mount PCB i think any
average electronic tech could get a couple of wires soldered in there
 without the cost being too exorbitant.

cheerio,
-doc

There is a silkscreen layout in the manual. If you feel comfortable 
working with surface mount electronics, you can put a switch in 
series with D6. With D6 disconnected, you can use the "Clock 
Out" jack as a "Clock In" for a 0 to 10 volt square wave. The 
pattern advances on the raising edge.

The "Master Clock" program I wrote for the PSIM was intended to 
provide MIDI and DIN clock out using the Noise Ring as the 
master. But I never figured out how to use the timer interupts to 
measure the tempo of the square wave from the Noise Ring.

Manual???? what's that? (oops!)
;'>
as usual....
a much more elegant solution than mine!
;'>
ThanX Professor!

PS(im)
pls forgive the OT...
re: 'click-timing' on the PSIM
did you ever try my pgm: syncable.bas?
it's on Brices Yahoo Group, in files/program code/code
fragments/MBASIC/syncable.bas
it's a 'starter recipe' but the timing clicks can be held to a very
consistent rate if you're careful to keep the interrupt routine lean
