Hi, I've using Flex Pitch on vocals. I have vocals on 4 different tracks. Flex Pitch worked fine on three of them, but for the last one, each time I turn on Flex Pitch, it mutes the vocal section I'm trying to analyze. I don't see the MIDI note versions appear, with the six little dots, like I do on the other vocal sections. All the vocals were recorded at the same time. I can't work out why this one section should not be working. I've closed the project down, turned Flex off and on again, and it keeps happening. Any ideas? It recognizes Flex polyphonic, but when I change to Flex Pitch, the vocal is muted? Am attaching two images - with Flex Pitch (sound it muted) and with Flex polyphonic (which plays as usual)
