Hey, Are there any patch connections that are not allowed to do? I tried to make a patch for the Superbooth Challenge and what I did is: I patched 2OSC first oscillator saw out into a multiple. Also patched a VCA out in the same multiple. And I put a third cable in the multiple and from there I patched one time in the 2OSC second oscillator sync and after that I tried its cv in (not sure which one I tried first). I tried audio and dc settings on the VCA. Now the 2nd OSC is dead  . |

You are generally only supposed to patch outputs to inputs. A multiple is not a mixer. You should only patch one signal into it, and then use the other sockets to patch copies of that signal into other inputs.
Here’s a video about multiples (it’s for a Eurorack but also applies to AE Modular as well):

Ok thanks. I understand. So does a mixer limit the signal even if all potentiometers are at full level? I mean that's 0 ohm then, right?
Or is it more complicated than I think? I am not an electronic expert I have to say.
I used multiples a lot of times like that... I thought it will not destroy anything because it's such a low voltage... But ok, good to know.

With a mixer on a modular synth, typically "all the way up" is 0 level, and everything down from there is minus-something. There are a few that can boost above a certain level, but these tend to be for audio only. And yes, you MUST use a mixer (or an adder, or an OR, or other similar devices depending on what's being combined) to combine outputs. Multiples aren't the right tool for this; the reason you haven't blown something up by combining signals with a mult is because whatever you were using had diode protection on the output to stop reverse voltages (very bad), and you got lucky. But even with some devices having reverse voltage protection on their outputs, the rule of thumb is to NEVER directly connect an output to an output.
Sort of reminescent of the old Serges, this...those didn't have diode protection, and given the rat's-nest methods of patching with bananas, it was alarmingly easy to make something go boom. At least the AE doesn't use that patching method...

Ok I will not do it again... Just had something in mind like I did read nothing can happen... But it doesn't count for this case. Somehow today the osc works again.  Thanks |

Thainks Luckily your conjuring of the magic smoke didn't complete - always a good thing. About a year ago I managed to complete the ritual with my Microbrute accidentally by doing pretty much the same thing. Lucky for me Arturia were very understanding and they shipped new boards for free. I am more careful now. I am pleased that your oscillator survived the ritual. |
