Hi all. I have bought Hosa splitter cables like this: https://www.rubbermonkey.co.nz/Cables-Connectors/Audio-Cables/Mini-jack-Cables/Hosa-YPM-523-1`4-Male-to-Dual-3-5mm-Female-Stereo-Splitter-Cable-6
They split TRS into tip and ring. I have verified that these work by running audio in and confirm these are splitting to let and right (ie tip and ring).
The curious thing is that these do not work with cv from the A4 unless I pull the Eurorack cv cable slightly out of the tip (or ring) end of the splitter. This is odd to me, since audio seems fine if the cable is snugly connected.
To be clear, cv output works fine from the A4, I just need to pull the Eurorack patch cable out a bit, so that it is unstable.
I suspect I am missing something fundamental here.
