Elektron Musical Instruments

I have a strange issue with my MD which I have already talked to Elektron 
about and will do further.  They have asked me to email them some 
patterns for their analysis.  However I am curious to hear if any other MD 
owners have ever had this problem.

So far I cannot identify any particular cause, but all I can say is this:  On 
certain patterns that I create on the MD, the tempo LED will start flashing 
erratically.  It doesn't blink in tempo, it just blinks randomly, often staying lit 
for longer than it should.

This is weird because it only happens on a few patterns, and it is most 
definitely a pattern-specific problem.  Bizarre.

So, has anybody else noticed their tempo LED acting strangely?  Please 
let me know.
