Thank you so much for your help, really appreciate it.

Thanks, I'm so sorry, I'm still confused, I can get the Envoltera to "work" in a patch by adding my MST dual VCA, see my "got it working" post on page 2 here:

https://www.modwiggler.com/forum/viewtopic.php?t=288783&start=30

The MST is a VCA, Envoltera has an internal VCA, I should be able to remove the MST?

If I can remove my MST, where do its IN, CV and OUT cables get plugged into on the Envoltera?

Thank you for such a quick reply Stefan. I really enjoy your designs. I am up to 15 of your modules at this point! I did some testing this morning and took some pictures that I will attach.

Chasing Lights

First, thank you for reassuring me about the resistor at RB_C is the one I need to modify for the running lights on my Chasing Lights. Ill experiment with some thru hole resistors I have on hand to find a resistance that lowers the brightness to a point I like and then order the appropriate SMD resistor.

Influencer

I was apprehensive about plugging this one back in, but took the chance and hooked it up. Perhaps it was a bad IDC cable connection on my initial test, as this time it worked without issue. I hooked up a few other modules on the same bus and they did not lock up this time. I will order the missing part and test again to make sure it is good to go.

Singer

Here is a scope test of Singer. A basic sine out of Alstaden. At full dry, the output is around 75-80% of the original signal, and much less at 50/50. The LFO works as intended, at least on the A side. If I flip the switch to B the LED lights up, but I get no signal at all if an oscillator is plugged in. I do get BBD chip noise oscillations out of the output when I crank feedback. My new issue is that the VCA is not working for either A or B. Putting CV into the input does not effect the incoming signal at all. I tried both an LFO and a static voltage. Perhaps that may be my B side issue, considering I can hear chip noise, but not input noise.

Hans

I do understand and expect lower output with increased resonance on filters, it is fairly common and I have others that operate similarly. That being said I still feel like it is not operating correctly. With resonance at 0 and cutoff fully clockwise my output is less than 50% of my input. I do not get subtle resonance at noon on the knob, only further lowered output. Resonance is only barely noticeable at 75% and beyond, but barely audible. In the following pictures the top sine wave is input, and the bottom green trace is the Hans output.

Again, thank you for the help! It's excellent that you take time out of your day to reply back, especially for a DIY project. If you need pictures of the boards themselves I am more than willing to do that as well, just let me know.

Hey Michael, You can solder L4 either way. Your issue must be somewhere else. So, the LT1930 is soldered properly, no bridges between the pins? Cheers, Stefan
