Prefacing this with that I am not sure if this is an issue with the HAPAX or the FH-2
For simplicity sake, I had been connecting my FH-2 to the HAPAX directly via the USB host connection on the HAPAX (so USB-C on the FH-2 to USB-A on the HAPAX). My FH-2 is set up with expanders to handle a number of midi channels (multiple monophonic converters, CC->CV, drum triggers, etc).
For the most part it has worked fine, but at a certain point, depending on the “load” of the USB midi connection, I start seeing/hearing dropped gates/triggers (i.e. stuck notes).
I was able to switch the FH-2 to use a standard DIN connection to the HAPAX instead, and that appears to have resolved the issue. I can work with this if needed, but I am hoping to root out the underlying problem.
I don’t think its a loopback issue, as looking at the midi monitor on the HAPAX, there was nothing incoming to it.
Anyone have thoughts/things to try? or anyone else experience this issue themselves?
