i'm using windows 7 64 bit and i have the realtek hd audio manager... dunno if that helps... um
i put the audio track input to MME devices > left stereo mix. arm the track and press record, i'm guessing that some settings were left behind from last time i converted midi... it's been awhile since i've used the program though and it seems like i keep having to re-learn this stuff every time i work on a project.
does any of that info help? thanks for your help btw.
