Hi all,
Here’s one thing that helped me quite a bit in this issue (on Windows 10).
First, I removed all drivers that connect to the Polybrute. Go to the windows device manager (open the start menu and search for “device”, should be the first hit).
In the view menu, enable the option “Show hidden devices”.
Expand the node “Sound, video and game controllers” section), right-click all the device entries “Polybrute Midi” (don’t exactly remember what its called, but like that) and click Uninstall.
You may also find it displayed in a separate section “Arturia” of the “Device manager” - delete those as well. And you may also have to check the “Delete the driver software for this device” box to ensure properly uninstalling the related driver as well.
When the uninstall process is complete, unplug the device.
Restart your computer
From there, please reinstall Polybrute Connect before plugging the Polybrute back again (once having restarted the computer).
One reinstalled, plug it back again and give it another try. In my case, it didn’t work properly still. Go to the device manager again. You now might find two entries. One is called “Polybrute Midi”, the other something similar. While one device is shown as properly installed and working, the other has a warning ⚠️ indicator. Right-click on the properly installed device, go to properties-driver-driver details and note or cooy the location of the Polybrute Midi driver.
The right click on the not properly installed device (with the ⚠️) and choose to manually install the driver. Point it to the Polybrute Midi driver you noted before and install that.
In my case, since then it works.
Hope this helps.
Daniel
