Just hooked CV up to the Brute and it seems fine, though I didn’t check before the re-calibration. Not sure if CV is included in that routine as I pretty much started it and went for coffee.
As for it being a bug, that was my first thought since Ext In/FX were good… there was some output from voices but I was needing 50db+ gain in my DAW to hear anything that wasn’t spiky high frequency stuff like that is in the soundcloud link.
As for random things sending kill commands, really needs to be a toggle in the globals to disable such unless you’re booting up holding Function or something. I realise there needs to be diagnostic commands but it shouldn’t be so easy to stumble on them.
