I have this problem on both of my computers. Two types of soundcards. When I check the midi devices in Control Panel>Audio, my midi devices are "MPU-401" and "Microsoft GS Wavetable". The Microsoft one can properly generate midi music on all my other midi softwares: Finale 2003, MidiNotate, Music Masterworks, Winamp. But Cakewalk(any version) says "No Midi outputs are selected". So does that mean I can't use Cakewalk on this soundcard?
