I've been trying to mimic a high-treble instrument I heard in a song where it basically goes between octaves in a wavy, smooth pattern. To do this on a piano you hit the note F3 then F4 repeatedly. But I want to make it automated and much more smoothly in Ableton Live.

Do you get the effect I'm going for or is a soundclip needed? I can produce one and post it to vocaroo or someplace.
