Question When I check the status of my TC Helicon device within VoiceSupport, it says the device is "In Use" and I can't update firmware or manage presets. What do I do Answer First off, if you are using a unit with both MIDI ports and USB, please make sure that MIDI control is set to USB in Setup. If this has no effect, please try the following: This error is especially prevalent in Windows 7 64 bit, but can affect other Windows based installations as well. There are a couple of reasons behind the "In Use" error, both of which are Microsoft errors, not a direct issue with VoiceSupport or your device. The possible solutions to these errors require registry editing within Windows. A helpful TC-H user has created an .exe file to automatically try to resolve the problem for you. With any 3rd party application, we cannot be responsible for any negative outcome as a result of using the software, so use it at your own risk.
  • Download and install/run the MIDI Cleaner application:
  • Select all but one of the instances of the MIDI driver from the main window. Click the "Clean From Registry" button.
  • If the "Create Upper Filters" Icon is highlighted, click that too.
  • Close the program.
  • Disconnect the TC Helicon device from your USB port.
  • Reboot the computer.
  • Reconnect your TC Helicon device and let any drivers install.
  • Restart VoiceSupport.
In VoiceSupport, you should no longer see the "In Use" message. If you now see "Not a TC-H Device" as the status, you should refer to this FAQ for further instructions.
