Hi list,
	Having despaired last night at not being able to clock my A-
117 digital noise module with my A-111, this morning I took penknife 
and soldering iron to it. I have 'reconfigured' it, moving one of the 
Schmitt triggers from being after the internal clock but before the 
input, to _after_ the input. It now 'squares up' the incoming clock 
signal immediately before passing it to the shift register generating 
the noise. The upshot of this is is now I can clock it with just 
about any oscillator: whatever it was about my A-111 output it didn't 
like before (even the square wave output), it will now happily run 
from any of the outputs; previously if I tried it with an A-110 it 
would invariably settle into a weird, (non-noisy) steady oscillation 
state - now it runs noise-like as I want it to. In fact it will run 
from any attenuated sine wave as long as it is greater than about +/-
1V in amplitude.

The modification requires cutting 4 tracks and adding 4 straps (and 
is moderately fiddly). If anyone else has been experiencing this 
frustration, and wants to know the details, let me know and I shall 
write some instructions and post them (and if I can persuade my mate 
with the digital camera to visit and take a few snaps of it, post a 
few pictures too).

Cheers,
	Tim

And vactrol filters and phasers...

Regards,
Kevin

Hi ph

Aren't there some guitar foot stomper boxes that use vactrols for
compression (boss CE2 ?). It should be quite simple to modify them.

hi
yes please, I would like A117 to work with A111 as well
please please, some details about how to do the change.
doepfer kinda said they would put a page about simple module 
modifications in february but they didnt
thanks
Alexandre

For those that expressed an interest in this, I have created a folder 
in the 'Files' section containing a text file of instructions, and 
three photos of my modified unit. (Thanks go to Mike for the photos.)

Any questions or comments, then get in touch!
