I know that sound like a strange question, but has anyone used CV-gate to send an A4?
The reason I ask is because on my system it can’t.
I was working with a percussive instrument that only had nine notes defined, so CV-Gate seemed an easier approach than CV-MIDI. I wired up the module and routed it to the external MIDI instrument:
and it works, provided I don’t send it A4. All the other notes work. But when I send it A4, it always either produces harsh and surprising output (occasionally), but usually it just crashes:
[175.533 fatal src/main.cpp:45] Fatal signal 11. Stack trace:

As you can probably tell from the stack-dump, I’m routing MIDI via Jack:
I had never worked with the synth before (linuxsampler), so I thought the issue may be with it, but I tried different sample sets and then an entirely different synthesizer (zynaddsubfx), and the behavior is consistent: rack crashes when I ask it to play an A4. Works fine when I use an external MIDI keyboard in lieu of the CV-Gate module.
Has anyone seen this before? Has anyone heard the clarion bell of 440 Hz wafting from their speakers when using CV-Gate?
It’s really, really weird.
