No, although that sounds cool. You basically had about 6 preprogrammed  
patterns for the bass drum, 6 other ones for the snare, etc. You chose one (or  
more, you could 'or' them) for each instrument and a meter (3/4 or 4/4 I  
think were the choices), and that was it. You couldn't change the patterns.  
Unless you took out the soldering iron, and started patching the pcb with the  
matrix of 1n4148's on it. B-)

I don't have it anymore, but it was in early 1970's Elektuur. Back when it  
was a Dutch-only magazine.

I'd like to see them again as well.
