Midi feedback loops and other questions

Is the best way to avoid midi feedback loops simply to disconnect a midi source from itself? For example input a goes to outputs b thru c; input b goes to outputs a,c and d, but not b.

Also, I notice that channel filters work intermittently.

Finally, I would like to request a midi monitor window, since both midi-ox and midihub editor cannot be opened simultaneously.

To complicate things further I am using inputs a - c from controller synths and clock from input c.

if I use more than a single usb output are they all transmitted through the single usb hardware port?

any help welcome, thanks in advance

It depends on how you have wired everything. There’s nothing wrong with sending data from input A to output A, or input B to output B.

Yes, this was suggested before, we’ll look into it at some point.

Btw, what issue do you have with MIDI-OX and the Editor? I run them both at once all the time. :slight_smile: The software themselves don’t interfere with each other, as Midihub Editor does not even use MIDI APIs. DAWs and other audio software may interfere with MIDI-OX, as only one program at a time can have a MIDI port open on Windows. Still, that means you can have USB D port open in MIDI-OX, and the rest of USB MIDI ports open in a DAW.

The physical connection is the same, but the OS sees Midihub as 4 MIDI input and 4 MIDI output ports. See https://blokas.io/midihub/docs/usb-midi-port-mapping/ to find out the OS naming of USB A-D ports in the Editor.


Got rid of the midi feedback loops by virtually disconnecting the output from the input for example
if the Prophet has a input on midi port a I send it to every midi other port but not a.

I now see that the midi ports seen by midiox are the usb ports, I wonder if that is also true for the mpc?

I also now see you do have indicators for midi activity, as leds on the unit itself, however I still encourage a desktop window as some of us put the unit under the desk.

As for the midiox error, it’s intermittent, something about not enough memory oddly enough, more on that as I capture it.

thanks for the help

Yes, MIDI-OX does say that when the MIDI ports are in use by another application. :slight_smile: You may review the list of ports MIDI-OX uses, and select only ones that are not used in other software.

Ha! The usb ports are represented as midi inputs in the mpc one as well.
