MIDI Port names change in Windows

Hi specialists,

I am facing a big issue with the communication between my Piano (Roland RD2000) and the GP.
After restarting it seem that GP recognize my Piano (connected via USB to the notebook) as another Piano as before. GP put‘s a „2-„ (as second device?) in some Settings.
For example: before restart the set up everything was working well, four of my sliders of the RD2000 I learned to sliders in Rackspaces and they reacted well. I learned the lowest keys of my Piano to change the Rackspaces. It’s not doing that anymore.
Any idea what I have to set up?

I do not know why this happens,
but when you use Rig Manager it is just a Single assignment to change and all is working fine again.

Hello Paul,

thanks for the feedback.
I didn’t thought about that yet, will check.
For the future I would like to avoid that… I would like to switch on the system and it should just run.
I am sure it’s a Setting somewhere…
Let’s see, I will give a feedback.

It’s a fantastic pice of software in combination with a
fantastic community in this forum here.
I appreciate much!

Short feedback,
it seems as the Ric setting could be the reason.
I had a Ric for home set up; changed it back to my „main“ set up. So far it’s working well.

I will report if it’s not the reason.

Unfortunately it is not sending the program change signal to the Drum anymore. I assigned it as the drum was named „TD-27“.
Now the Drum calls in the system „4-TD-27“ and I do not know what to set in the Ric manager to get it working.

I do not really understand.
What is sending a pc message?
Drums is a plugin?
How looks your rackspace and rig manager?

„Drums“ is a real E-Drum with the name TD-27.
In each Rackspace I have a MIDI out Plugin which sends on MIDI Channel 10 the Programm change to the TD-27 when I choose a Rackspace.
As the TD-27 is now recognized from GP as 4- TD-27 the MidiOuts were not working anymore.
I change now all MIDI outs to the 4- TD27 by Replacing the Plug-in.
I still would like to understand what was/ is causing renaming the TD-27.

Maybe that helps:

And don’t forget to read the linked article within the post from superuser.com where you can find some more information about this typical Windows issue:
How to solve the infamous Windows 10 MIDI device renaming issue | by Paolo Pustorino | Medium
I guess, this could be very useful for some of our users that already ran (multiple times) into this “trap”!
Thank you for finding this! :+1:

This is great to know. I’ve added a knowledge base article about this topic



Thanks! I will check it out when I am with the system again!

I checked the Info.
I changed the USB connection as well, due to the new Notebook cooling plate… so that was the reason.
As I understand it correct with the recommended software in the article it’s possible to re-name the USB devices after changing the connection, but not to avoid the automatic re-naming from windows.
It’s important to know and to consider when setting up and connection the equipment at live gig‘s -




This is not the first time I see people having this problem, but I never take care of which USB I using and I never had this issue. Perhaps lucky until now :grimacing: :innocent:

Some manufacturers explicitly specify to always use the same usb port while for other equipment it does not matter.

However, each connection of the same device to a different usb port leads to the installation and writing of an impressive amount of data (configuration, authorizations, writing to the registry, etc) that will progressively encumber and degrade the system.

Using a unique usb port for a specific device contributes to optimize the system.

Npuder contaminated me… :smile:
