MAINTENANCE  my drumbox had trouble with the m250 and lost some patterns, there's quite nothing to do about those kind of issues.   I have no information about this kind of chip. If you have more information just write us.

Our Verdict 

" Fun  drum machine preset, does not sound bad at all! This model  is a bit hard to find, but there are many alternatives if you're into preset drum vintage "
