MisterGreen Posted October 9, 2020 Share Posted October 9, 2020 I recently received a fatal error while adding Miroslav Philharmonik 2 to a new project (image 1). So, after the program closed, I reopened it, started a another new project, and this time, tried to add an instance of Kontakt. The instrument opened successfully. I added a library and as soon as I touched a key on my controller (Nektar LX88) I received another fatal error (image 2). So, out of curiosity, I opened device manager to look at my USB drivers and noticed two USB controllers listed under Other Devices that had the yellow alert icons next to them (image 3). I opened each one and took screenshots of their properties (images 4 and 5). Not sure if they are related to the crash but it seemed it might be a USB driver issue.

Jeremy Oakes Posted October 9, 2020 Share Posted October 9, 2020 Whilst you were in device manager, did you click on the Drivers tab and update said drivers ? Jerry Link to comment Share on other sites More sharing options...
MisterGreen Posted October 9, 2020 Author Share Posted October 9, 2020 Yes, I did try that. Windows could not find a suitable driver. Link to comment Share on other sites More sharing options...
MisterGreen Posted October 9, 2020 Author Share Posted October 9, 2020 In the meantime, I'm going to switch my LX88 from USB power to AC. I'll see if the issue continues. Link to comment Share on other sites More sharing options...
reginaldStjohn Posted October 9, 2020 Share Posted October 9, 2020 From the images it looks like the LX88 driver is having problems. I have this exact same problem with my LX88+. I have worked with Nektar on it and they had me re-install some things but nothing made it any better. I Recently upgraded my computer and re-installed everything and have not seen the crash yet. However, I haven't used my controller much either. Link to comment Share on other sites More sharing options...
MisterGreen Posted October 9, 2020 Author Share Posted October 9, 2020 The LX88 doesn't require drivers (according to Nektar anyway). That's why I went straight to the USB since the two errors referenced two different USB devices. And reading up on the motherboard, it looks like there are 2 pair of USB ports controlled separately; one by Intel and the other by ASMedia.

reginaldStjohn Posted October 10, 2020 Share Posted October 10, 2020 Well, not a USB driver but the control surface driver or interface binary. The DLL shown in your first image is a driver of sorts that interfaces the Nektar to Cakewalk. That is what was crashing on me and that is what your image shows as having the exception. As for the USB ports that don't have a driver installed you could try to delete them from device manager and see if they get re-installed. Try to update your motherboard drivers etc. Or just disable them and see what happens. 1 Link to comment Share on other sites More sharing options...
MisterGreen Posted October 11, 2020 Author Share Posted October 11, 2020 While I wait for the power adapter to arrive, I unplugged the Nektar from the USB port on the mobo and connected it to the port on the front of the case to see if it would give the same error. So far, it's working. I checked the ASUS site for driver updates and it looks like I have the latest. I'll try your suggestion, Reginald, regarding deleting the devices. I'll let you know how it goes. Thanks! Link to comment Share on other sites More sharing options...
MisterGreen Posted October 11, 2020 Author Share Posted October 11, 2020 So, I uninstalled the two devices and Windows was unable to reinstall them. As for the original error, it happened again. So much for trying a different USB port. Were you able to resolve the issue with yours? Link to comment Share on other sites More sharing options...
reginaldStjohn Posted October 11, 2020 Share Posted October 11, 2020 The only way I resolved it was when I re-built my computer. It actually still many have the error I just haven't used it enough to verify if it is fixed or just waiting to happen again. 1 Link to comment Share on other sites More sharing options...
Bill Campbell Posted October 15, 2020 Share Posted October 15, 2020 Hmmm I'm having the same issue with my LX88. Looking at the dates of these posts it seems like the problems started around the same times as well. Makes me this the root cause might have been a Windows update. I'm considering removing the USB driver all together and using the MIDI DIN out instead. BTW When I first got my LX88 it worked fine.... Link to comment Share on other sites More sharing options...
MisterGreen Posted October 21, 2020 Author Share Posted October 21, 2020 Hey Bill. I have updates turned off on my machine so it's definitely not that. I reached out to Nektar and they sent me a different version of their utility for Sonar and I haven't had a problem since. Link to comment Share on other sites More sharing options...
Bill Campbell Posted October 21, 2020 Share Posted October 21, 2020 Hmmm... maybe I'll give that a shot. Thanks... Link to comment Share on other sites More sharing options...
