You might want to look at Prefs, Channels and make sure that the drum channel didn't get changed from 10 to a different number. In GM MIDI, drums are on channel 10.

The Forte, as well as your Ketron hardware unit should respond properly as drums on channel 10, so check to make sure it is actually outputting to channel 10.

My system worked fine, so I unfortunately can't replicate your problem.
