Kawai Synthesizers

I now have my K1 working completely but for one curious thing. I am 
testing out Rhythm Rascal, which allows you to create drum patterns 
and then export them as MIDI. When I import the MIDI file into CBase 
SX3 the K1 ignores them completely.

All other MIDI sections play fine, the channel is set to 10 yet 
nothing. If I swap the channel to, say, 7 and select Bank 0, programme 
3 then I hear the pattern via the strings section but reset it to 
channel 10 and nothing.

What am I doing wrong? I know the K1 was pre-GM so the GM Drum Map 
won't work but should I remap the drum setup for the K1?
