MIDI out using USB rear connection?
Posted on 27 Mar 2021, 03:47 AMHi,
Is it possible to send MIDI out messages (knob assign) using the USB rear connection or is it possible only using the DIN connections?
I have the EFM connected to a USB hub and into Cubase but I can't get the knobs to send MIDI data that way. I did enable the "send to MIDI out' option.

It's only possible using the DIN connectors. The rear USB is MIDI-IN only

Looks like if the EFM is connected via USB and additionally with a DIN just for MIDI out there is some crazy feedback loop going on.
What I tried is to add MIDI CC automation to a track in my DAW (Cubase). What I noticed is that while playing a sequence, if I move the knobs to add automation the playback on my DAW is glitching and the entire process is very choppy. Even after finishing the recording process the track would play choppy and skip beats etc.
I tried this with two different MIDI interfaces (the MIDI port on my RME Fireface 800 interface and on an iConnectivity interface) and they gave me the same result - in fact when I used the iConnect it crashed my computer when I moved the knobs on the EFM.
None of this is happening when I just connect the EFM using 2 MIDI cables for In/Out so that's why I am assuming there is some kind of feedback loop going on if I combine teh USB and DIN connection even though I only use the DIN to connect the MIDI out...

That's usually what you want when different synths are connected together, but here it's the same one. Are both DIN and USB are connected to the computer ?
That would be great if we could get a drawing of your setup to better understand what happens

Here's a drawing:
Posted on 03 Apr 2021, 07:49 PMYour computer/DAW is probably sending back received MIDI from USB #1 to USB #2. I am not familiar with your DAW but maybe it has an option to prevent that.
The easiest solution would be to remove USB and use DIN for IN and OUT plugged into your MIDI interface.
Using both USB and DIN at the same time mostly make sense when connected to different devices, not to the same one.
