This may fix other issues too, so give it a try.
If you have had issue getting your firmware to update and/or Analog Lab and Midi Control Center to work with your Keylab 49 or even have problems getting it recognized as a MIDI device, then I may have found the solution to your problem. The problem is there is Registry key missing!! It is deep in your system and causing all this stress.
I did this and FINALLY my Arturia is working with Analog Lab and Midi Control Center. I suspect it will fix many other problems.
Arturia Technicians LET PEOPLE KNOW ABOUT THIS!!!
It may not fix all problems but MANY problems are having problems getting their Keylabs to work with their Analog Lab, MCC and other programs
1. Download Midi OX for free
2. Got to . Options > MIDI inputs and MIDI outputs > Select Keylab 49/61 or whatever Arturia MIDI instrument you have
3. You will see it gives the message Undefined EXTERNAL error...that's ok it is confirming their is an error
and HERE is how to fix it so your software works with the Arturia
I will post a link but basically it is a Registry Key problem so EXPORT AND SAVE YOUR REGISTRY FIRST!!!
Then go to http://avid.force.com/pkb/articles/en_US/Troubleshooting/en416511
and follow these directions
If your M-Audio USB MIDI device, or the MIDI input on your M-Audio audio device, is recognized by your applications, but does not receive MIDI data from the device, test with MIDI-OX to see if you receive an “Undefined External Error” after selecting the device and clicking OK in MIDI-OX’s MIDI setup
If you get an undefined external error in MIDI-OX, try the following steps to resolve the error. These steps require that you modify the windows registry.
NOTE: YOU SHOULD ONLY DO THIS WITH THE UNDERSTANDING THAT YOU CAN CAUSE IRREVERSIBLE DAMAGE TO YOUR SYSTEM IF YOU MODIFY REGISTRY KEYS OTHER THAN THE ONE SPECIFIED BELOW. PLEASE PROCEED WITH CAUTION AND GO THRU EACH STEP CAREFULLY!!!
Hold down function/Windows key and press the letter R. This will open the Run window.
Type in: regedit to open the Registry Editor
Press CTRL + F on the keyboard to open the search window.
Copy and paste the following key in the “Find what” field.
(make sure there are no leading or trailing spaces)
You can confirm that the search function has located the correct key because the (Default) value is “Sound, video and game controllers” and the Class is “MEDIA”
Right-click in a blank portion of the right hand pane and choose New -> Multi-String Value
Under the Name column right-click on “New Value” and select Rename
Type: UpperFilters (case-sensitive, all 1 word)
Next, double-click UpperFilters and under "Value data:" type ksthunk (case-sensitive)
Click File > Exit to close the Registry Editor, and you should now be able to successfully select and use your M-Audio device.
You can again Test your device with MIDI-OX to verify that you are no longer receiving the Undefined external error.
Hope this helps all the people I have seen with related problems. Maybe I have saved Arturia many thousands of dollars with this solution!
Now I'm off to make some music and show this synth off to some legendary electronic music artists
Hey Arturia, will you give me a sales commission?
PM me, I love to sale equipment that I believe in.
