I have been curious about the Bk-7m for quite a few months now. I'm surprised that there is relatively little information with regards to reviews on it. There are only a few people with youtube videos demonstrating it. Can anyone steer me to the latest reviews on this? Is there anyplace to hear samples of what the styles sound like? What are your opinions so far? I'm looking for a good rhythm machine (not just drum machine) to go with my keyboard.
