Hi my friend,

Midi drums will only play if the style came with them. Remember that audio drums and grooves are pre programmed loops that you select from the libraries. Not so with midi. Most origal ketron styles won't have midi info for the drums as they were created from scratch using audio drums. However, converted 3rd party styles comes only with midi drums which you can rrplace with audii drums. In this case my advice to you will apply. I hope this is clear.

All the best my friend,

Henni
