I just got the Hermod a couple of days ago for the same use with Sensory Percussion. Just today I realized that I may not be able to use it as a straight up “MIDI CC in - CV out” converter. However, you can use MIDI CC’s for internal modulation of various parameters via the ModMatrix as Andreas said. As I’m only a couple days in, there may be something else I don’t realize.
Looking forward to exploring all the possibilities with the internal modulation possibilities, but I am a bit disappointed I can’t use those CC’s from Sensory Percussion for CVing the rest of my system. I was using a Vermona QMI for that purpose and I was envisioning replacing it with the Hermod, but I guess I’ll hold onto both for now.
