Hi tim,
I plug my Faderfox EC4 directly to the HAPAX via USB.
I check the sellected track to have ALL ACTIVE as midi input.
And as I push 2ND + LIVE and turn a knob on the EC4 the left display shows incoming data.
If You do exactly this, aren’t You able to confirm that?
I indeed do the same. Did double check the incoming port on the track, but those are all on all active. Ec4 is direct via usb on the host usb of the Hapax. No midi input shownn
Correct, no hub in between. I was searching for a Factory Reset, might help, but no idea to do it and also can’t find it via manual or Google.
Super weird. Those controllers are no strange exceptions, so must be doing something wrong. Check all midi settings, nothing wrong as far as I could tell.
Hey - I also have the same issue with midi coming from and going to my Moog Sub37 from the USB host
In the beginning it did not work, changed cables it worked for a bit but began to start failing and missing notes both ways, eventually stopped all together (Moog did not receive and was not able to send midi to USB host - note that even here the Hapax was indicating that it was sending midi). Anyway, at that point I gave up and routed it via the Midi Din. Still not sure what the route cause of the issue is but certainly is a valid issue - what you described seems very similar.
Also, in my experience, for some devices, midi via usb can be rather sensitive when it comes to cables, so in that kind of situation, always try out some different ones.
Roland devices typically are not USB class compliant (ie require OS drivers) and those will not work with a generic USB-MIDI host like Hapax. On some devices this is configurable, see the manual.
