Hey steve, I purchased serum on splice with the rent to own plan. I want to purchase LFO tool as well but when I tried   
on the demo I get this problem - 
(here is a short video that shows the problem exactly):

let me know if I need to do something in order it to not happen or this is just how it is.  
thank you! 
 
  
  
  
  Try shifting the MIDI which is triggering LFOTool to be a little earlier or later, I can't really tell from here without seeing the MIDI notes, but it seems that the note on the start of the cycle might be fractionally before the bar.
 
  
  
  
  you right, when I shifting the midi to start a mili sec later it works perfect! funny
when the note  exactly 100% on the first beat its doing the problem. maybe it something with cubase 7?
 
  
  
  
  Great service and fast response! gotta say that btw. 
 
  
  
  
  Thanks, glad to hear - loopback of a cycle can be strange in various hosts (cubase and Logic most notoriously).  There might be something e.g. a preference or not having the track record-enabled, etc which might solve it.    Cubase 8 also has a lot of internal re-writes and improvements to that might be something to try or consider.
