I did this mod. Basically, the menu values do still adjust the sound for both cutoff and resonance (41 and 42 i believe), but the knobs tweak the sound as well. I had a hard time with this as well because you never really know what the setting is at when the mod is installed. I do know that you cant get any sound out of the mod knobs if the values inthe menu are really low (like a value of 1-3 or so), and if you exceed the 13 value for resonance you get some really sharp sounding noise out of it (watch those speakers). You can do the same thing on any of the pots (a knob is the same thing as a pot, just it hasa knob to tune it instead of a screwdriver. So who knows, maybe you could get some more value out of it with more knobs, but you are still dealing with the internal menu settings affecting the circuit as well, so it's kinda a double control issue at that point. Also, there are several different ohmage pots (knobs) that can be used and they all affect the signal differently. Obviously none of the mod knobs can be controlled via midi, so knobs settings don't mean jack to your patch info.
 
I'd recommend you get a low wattage soldering iron (15-30 watts) for working on circuit boards. Any solder should work fine. You may want to use some flux for joint work.
 
If you do this to all you knobs, you will obviously need a mapping to all those pots inside, which I am not sure I even know what they all go to. Let me know if you do...Better yet post it as a file in this group. Good luck to ya.

and i've come up with some questions.

With the moogslayer mod (don't have it, hope to get it) what exactly
is being adjusted? Is turning the resonance and cutoff knobs exactly
the same as tweaking the variables in the menu for these same values?
Does the range increase? From what it sounds like, the knobs must
adjust like ten times the range of the menu, turning the range of
values in on themselves, creating a time-space vortex, unifying sound
and matter, and sonically interrupting the molecular structure of
small children and pets. Does that sound about right? More
importantly, does the installation of the knob make it impossible to
use the menu to set these parameters, can you get back to an
"unmodded" position and work the instrument in a "stock" manner?

I see a whole bunch of those little pot switches on the circuit
boards, and i was wondering if each one represented a new opportunity
for adjustment via knob?

I've noticed that you can adjust some parameters in real time via the
menu, while others cut out and back in if you adjust them. For
instance, you can adjust the resonance and cutoff of the VCF in real
time, holding a note down and hearing the difference as you adjust,
but if you adjust anything about the delay (or indeed even switch to
one of these parameters in the menu), the effect pauses and then comes
back. Is this the difference between the digital and analogue portions
of the unit?

What i'm kinda hoping is to find that anything you can adjust on the
fly will have a circuitboard pot associated with it, and i can install
a bank of knobs to control other parameters like say the MG frequency.
What do you think?

When installing these mods, what specific type of solder and iron do i
use?


hmm. That's enough for this post.


hit me!
