Only able to send note data over DIN

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...

Here are some of the random pitchbends that are being sent with the ARP running or keys being pressed in play mode

As soon as I plug ARP in directly via DIN, everything seems to work as expected. 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!

So, I've spent some time with the H4MIDI WC and I cannot get it working. I tested everything I could find in the studio that outputted MIDI over USB. The Arturia MicroLab, KeyStep and Beatstep, Roland J6 and the Novation LaunchControl all worked ok for Notes and CC. However, the hub couldn't pick up any MIDI data from a Launchpad, LaunchKey, NDLR, BCF2000, MC-101, TR8 or SeqTrak. I tried @submo's suggestion of disabling Serial Output from ARP and that did nothing. Consecutively... MIDI Only build, stripping out all the Serial Outs, suppressing Serial.begin, even trying a simple Arduino UNO script with nothing but the MIDI Library added. No joy, I'm afraid. ARP's USB over MIDI works fine with other Hubs (such as Blokas or MRCC) and it connects to MPCs and other Arduino based gear via USB without any issues. I'm not sure what else can be done but I'll keep a look out for any info online. My suggestion would be to continue with MIDI DIN or upgrade the hub. Sorry it's not better news.

So, I got hold of the H4MIDI Hub again. So, I've tested the following Sketch: -

<pre> #include <MIDI.h>

MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI1);

void setup() {

Serial.begin(115200);

MIDI1.begin(MIDI_CHANNEL_OMNI);

}

void loop() {

delay(2000);

Serial.println("Send Note On");

usbMIDI.send(0x90, 66, 66, 1, 0); // USB = F#4

MIDI1.send(0x90, 48, 48, 1); // DIN = C3

delay(2000);

Serial.println("Send Note Off");

usbMIDI.send(0x80, 66, 0, 1, 0);

MIDI1.send(0x80, 48, 0, 1);

} </pre>

The script sends MIDI ON and OFF messages ever 2 seconds via USB and MIDI DIN When running this directly connected to the PC (MIDI DIN via a Focusrite 8i6), both USB and MIDI messages are received.

There's no name.c file. Any suggestions would be greatly appreciated. :)

Hey Chris,

I just tried this and was able to get it working.

I will send you an email with more info, rather than bog down this forum with techno babble ;)

Tried again but still no joy. I've sent more information via email.

Can you also confirm which Hub device you are using? H2, H4 or H6? I don't think it matters but the H4 and H6 are USB-C ports.

If you connect ARP to a PC or Mac via the USB, I assume it works OK?

Cheers for the extra info, The CME hub should arrive soon and I will dig into it.

Can confirm that although the CME H4 recognises the Midicake ARP when plugged into its USB host port, it does not seem to be correctly receiving Midi Data (i.e not receIving note offs).

ARP's USB Midi seems to function correctly when plugged directly into a USB port with Windows.

Not sure if this is an H4 or ARP issue. The H4 has had some compatibility issues and can be a bit picky when it comes to usb descriptors. My Teensy based USB Midi Interface seems to behave ok with the H4 and correctly sends note offs (although I have changed the default teensy USB descriptors a little).

Will try to spend some more time on this over the weekend if I get a minute or two.

So I've had a little play this morning.

I tried my Teensy USB Midi interface using the exact same default Teensy USB descriptor as the ARP (Midi + Serial) and the Midi interface seems to work fine on my H4, so I don't think the descriptors are the issue.

The only thing I can think of right now is that the ARP does send CDC (serial) messages over USB as well as Midi which may be confusing these host devices like the CME H4 as they are only expecting class complaint Midi. Might be worth completing disabling printing to Serial to see if that fixes the issue? (You could try the 'Midi' only Teensy USB descriptor, but even that has a emulated Serial device built in, which may have the same problem?).
