I just got Audacity 2.4.2 up and running on my Vivobook. First time user.
I can successfully open/import audio files and play them back, edit, etc.
I cannot get Audacity to see my M-Audio O2 MIDI controller as a recording option. My laptop chimes in acknowledgment when I plug it in, and has installed the appropriate driver. I have a MIDI monitoring utility that shows data coming in when I hit keys on the keyboard. The Device Manager for Windows shows the O2 under Sound, Video and Game Controllers. Windows does not, however, show the O2 under Input Devices-- only Stereo Mix and Microphone (both Realtek.)
Similarly, in Audacity itself, the pulldown recording device/input list shows Microsoft Sound Mapper, Stereo Mix and Microphone.
I have gone through the FAQs, wiki, tips etc to the best of my ability and cannot see how to solve this. Any advice would be appreciated.
