I am using Delta 1010LT with n-track. Recording analog guitar track, I get an error message that pops up and says “Error opening MIDI out device”. It still lets me record, but always shows that message. Any thoughts?
You need to ensure that the MIDI devices setting in Preferences is set to the correct MIDI device.
Also, I presume n-track is set to record both Audio and MIDI. Click on the Piano/Mic icon on the toolbar until it just shows a mic. Then you will only be recording Audio and n-Track shouldn’t (!) complain about the MIDI devices… unless of course it’s complaining that it can’t open the MIDI device for playback (? ? ?)
