Thanks for your response.
When I had first had success making a MIDI file from audio, it was using a snare audio track as my source. The MIDI triggers were way off though, not even close to the snare. The paramaters that would usually be available to edit are things like velocity and sensitivity, and that is one thing I am trying to find.
I'm trying to understand the relationship between Flex tools and Audio to MIDI functions. Is it Analyze that I must do first in order for Logic to determine where the MIDI triggers of the snare should be? When I select Analyze Audio for Flex Editing, the next menu option to Create MIDI Track from Flex Pitch Data then becomes unavailable.
Maybe I'm making this more compicated somehow but the Create MIDI Track option is greyed out and I can't figure out how to 1) analyze the audio to determine where MIDI triggers are 2) create MIDI from that audio.
