Hello, I am having trouble successfully using my v1.5 (1.5.8.5133) ARP on anything but DIN midi. I've tried connecting directly to a CME HxMIDI WC midi hub both via the directly powered USB hub, or using a CME Uhost connected to the installed BLE Widi Core as either a USB host or device. I can see it populate one of the USB-A slots in CME HxMIDI software, and I setup virtual routing to the other connected midi devices and ports on the same hub, but it will not send any note data. When I run a midi monitor on my laptop connected to the midi hub, I can sometimes see the ARP sending various 0 value ccs and program changes on various channels that are and aren't configured as one of the 4 arp channels sometimes, but typically it will just send pitchbend data on channel 2 most of the time. See below for a variety of the messages...

I've tried the 'all' as well as the various USB host and device combos in the settings, but every time I connect to something via USB host directly or with a widi dongle it just doesn't seem to work. I can use the DIN CME widi dongles ok most of the time it seems, so it's definitely USB related from the debug I've been able to do. I've flashed the device and factory reset it multiple times, but whenever it's connected to USB the experience is the same as described. I've tried pluging directly into my Squarp Hapax USB host port too, and it sends similar messages and pitchbends no matter which channels are configured according to the midi monitor. As soon as I plug it into one the Hapax din or TRS ports, it works fine. I don't know if this is a config issue (but since I've factory reset it it, I doubt so), but it's been pretty limiting in what I can do with the device, to say the least. Any help or ideas are appreciated! Todd
