Hi Joden,

You need to select something General MIDI-compatible (like the Coyote WT) as the Default Synth. It sounds like you just haven't selected a Default Synth.

Addictive Drums should only be assigned to the Drums track, but you'll get that error if that's all you've done,and the Default Synth slot is still empty.

If that doesn't help, please let us know which version of Band-in-a-Box you're using.

Thanks
Kent
