Hi,
You may want to start troubleshooting with and without the analog mic and the Motu ultralite mk3 hook up. Go to the Voxal Options menu, look for the recording device(it must be listed and set up on the Windows recording mixer settings, under the "Sound > Recording Windows settings" this device must be set as your default Windows recording device), select it and try to record/use the analog mic once again. Try also to record/use Voxal with a different microphone, or use the system integrated mic(in case you are using a laptop) in order to test.
In case you need further assistance you can always contact the NCH support staff at supportnch@nchsoftware.com
Best regards,
