No MIDI functionality via USB-C with Pacer, Midi Captain and M-Vave Chocolate

[t-ario]

Does anyone here have experience using one of the following MIDI controllers via a USB-C connection?

 

Nektar Pacer

Paint Audio MIDI Captain

M-Vave Chocolate

 

It is currently not working for me, so I am very interested to know if MIDI control via USB-C actually works with these specific controllers in practice.

 

Thanks for your help!

I have already sent the inquiry below to support.

Hello Line 6 Support,

my Helix Stadium Floor does not receive any MIDI commands over the USB‑C port.

 

Tested controllers:  
Nektar Pacer, Paint Audio MIDI Captain, M‑Vave Chocolate

All controllers were powered by their own power supply.
All of them work correctly via the 5‑pin DIN MIDI input.

 

Function check:  
All controllers send MIDI correctly over USB‑C when connected to a PC or laptop (verified with MIDI‑OX).
Cables and controllers are not the cause.

 

Helix MIDI-Settings are correct (factory settings):  
MIDI over USB‑C: On  
Global MIDI Channel: 1 

 

Additional steps:  
Factory reset performed
Firmware version: 1.3.1

 

Despite all tests, the Helix Stadium Floor does not respond to USB‑C MIDI.
Please check whether this is a firmware issue or a possible hardware defect.

I am seeing Helix Stadium responding to MIDI PC and CC from a computer (Mac) over USB-C. In Global Settings > MIDI be sure to have encoders 5 (Receive MIDI PC) and 6 (Send PC w/ Preset) set to "MIDI + USB.

Yes, that works.

 

I want to control the Helix with one of my controllers, not with the PC.

You need a USB host (like a computer, but there are other devices that provide host). It won't work to connect usb clients to each other.

I don't understand, but thanks for the info.
Where did the information come from?
I haven't found anything about it in the manual.
I haven't received any feedback from support so far.

Got it from general knowledge of many years as a computer programmer.  (Search USB host/Usb client) If you don't want a computer in the mix to provide host, you need another device that can provide host like a Morningstar MC4/6/8 midi controller, or others.

"USB-C PORTS: DEVICE AND HOST The Host port is a built-in MIDI USB host. With this, MC6 Pro can directly control other USB devices such as the Source Audio C4 Synth, Line 6 Pod Go and Zoom Multistomps. No need for a separate MIDI USB host that is both costly and cumbersome"
