I was pretty amazed by the effect an electric mistress can have on synthpads as demonstrated in this video. So I bought one of the latest reissues they released, which happens to be a v5. Here is a very informative resource on Electric Mistresses where I also got the schematics from, thanks to the creator of the page.
While examining one of my A-110-1s to help answer a forum question I noticed that it was equipped with a TL064 op-amp. A quick look at the schematics revealed that it is part of the waveform generation. I am not an expert but from what I´ve learned, the 064 is usually not the first choice for audio applications. So just for fun I replaced it with a TL084 I had lying around.

This is a follow-up to the general modification article.
In an effort to come up with a more detailed documentation for the mod I made an annotated picture of the mainboard followed by some explanations:

I have put together a CC mapping table for the DK 80 after the only mapping list I could find online was actually for the Expander 80 desktop version, which has a slightly different mapping.
Do you also have the problem that sometimes the an oscillator of your Behringer Neutron is out of tune when you bypass its tune pot?
I had that a couple of times now and didn´t know what to do about it until today.
I assumed being driven by 3340 ICs the Neutron would not need any warm up time but maybe I am wrong. However during boot the Neutron calibrates the OSCs internally. I found that when you lock a Tune pot and the corresponding oscillator is out of tune thereafter, you should switch power off and back on so to force re-calibration. Mine was perfectly in tune after having done so.
