I thought I would try to explain this better. The music passage I am playing needs 3 sounds. A marimba, a pad, and a lead trumpet sound. The marimba is playing 2 notes. I am using the arp plug in to fake a rapid mallet strike between the two notes. A Marimba roll. The Pad is playing the same 2 notes with no arp plug in. The Lead Trumpet sounds needs to be able to play ONLY the top note of the chord being played. Right now if I add the trumpet sound on a layer it will obviously play everything on that key range (set the same as the pad and the marimba) What I would like is a plug in that will scan what I am playing and only play the top note. Then I can have the trumpet sound playing just the lead melody line. I am playing something with my left hand already so I can't use that hand for the trumpet sound. I hope this makes mores sense. Thank you for looking and if anyone has any ideas I would love to hear it. I have scoured the web and haven't been able to find the answer.

Hi ! It's my first post. In Main Stage I have a situation where I need two sounds layered and the first sound plays a chord and the second sound only plays the top note of the chord. A Poly to Mono script ? Does anyone have any idea where I can find something like this ? Thanks ! Wayne
