Thanks for getting back to me, but GS is still not working. I have tried your suggestions and have even uninstalled and resinstalled Ear Master. Would you suggest I install a new GS driver? I'm grasping at straws at this point. I do have a friend with XP who is running Ear Master fine. I am going to...

GS Wavetable seems to be my only option

I've been at this for a while now trying to confirm sound card volume and mute settings for SW synth. I still can't get any midi sounds to work.
I'm running XP Pro SP3.
