I am having the exact same problem. 1) create audio track 2) crate midi track from flex pitch data. 3) the new midi region is added to the arrange page and I can see that the idi data in the region matches the pitches of my audio track BUT 4)nothing plays back 5) when I double click there are no notes to be found in the midi window and 6) there are no notes on the staves of the score window.
What is the disconnect between the analyzed data, the data shown clearly inthe region but not being sent to the Midi instrument or to the midi editor/score editor??
