Phrase trigger

Hi, I’m looking for a function inside Cubase to key trigger previously built midi phrases. I need something like this:

  • build several midi parts with all the possibile editing inside, including CCs
  • assign midi keys to trigger each part with different options (latch, repeat and so on…)
  • the parts then play according to the actual tempo

I know this is possible to achieve with Arpache SX midi plugin but the problem is that I have to create an instance of the plugin for every phrase I want to trigger and, altough described in the manual, I’m not able to play the sequences in latch mode.
Any suggestions are welcome. Thanks
