Hi all,

I have a couple of questions I hope someone might be able to help me 
with.

I was trying to find a way of having the 'length' of a single step be 
equal to 13 on the fourth bar of a repeating 16 step sequence (and 
equal to 7 on the other 3 passes). I decided that the best way to do 
this would be to use the  'Set Step Value' aux event to set a value 
of 13 and then use an acumulator mask to mask the 'Set Step Value' 
aux event.  I ran into a problem in that the 'Set Step Value' event 
has a max value of 12.  Am I doing something wrong here or is this 
likely a bug ?

Assuming that the aforementioned problem is a bug, is there a better 
way of achieving what I am trying to do ?

Any help appreciated.

Cheers

Simon
