MIDI keyboard suddenly stops responding in Sonar

[Ota Štanc]

Hi everybody.

I installed BandLab Sonar some days ago (switching from X1) and here's the problem:

I use Roland GO:KEYS as my MIDI input keyboard. First I used USB cable connection, it worked fine as well as my ZOOM R24 control surface. All of a sudden the MIDI keyboard ceased responding as if it was not connected - no meters action, no sound... When I check Preferences, everything seems normal, the device is detected and selected for input and output. I tried all the things like changing the cable, USB port, even reinstalled Sonar with no success. 

Then I switched the drive from MME to UWP, which allowed me to use Keyboard's BlueTooth MIDI. Again I am able to choose the device (see the picture). It only worked for 5 minutes and then - no reaction.

My OS is WIN10 64 ver 1709.

Any ideas? Thanks from The Czech Republic.

Ota

Have you checked if your control surface is still set up? If it's still there it may be using your GO:KEYS MIDI input/output as it's normal MIDI input/output is no longer there.

I've had this happen to me in the past - it took ages for me to work it out!

Try deleting the file TTSSEQ.INI in app data\roaming\cakewalk\cakewalk core.  You will then need to recheck the boxes for your MIDI keyboard in Preferences.

Have you made sure that power management for your USB root hubs is disabled
