Elektron Musical Instruments

subject pretty much says it all.  Ive got a kit using the arpeggiator 
on one of the channels and it *always* seems to want to latch if being 
triggered by the internal sequencer.   is there a way to turn this off, 
or at least sequence it to cut off?  I really dont want to have the 
arpegiator constantly running all the time after one note.
