Deluxe Electric Mistress v5 rate mod

Preface

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.

A-110-1 Standard VCO improved

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.

Behringer Neutron calibration

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.
