My project contains many time signature changes. It contains audio and MIDI files. The project is 248 measures. One part, the percussion MIDI part, however, doesn't appear to reflect the time signature changes and shows up, in the MIDI editor, as 101 measures of 2/4 - even though this part starts right at measure 1 and extends to the end (i.e. measure 248).
Obviously, this makes editing difficult. Is there something I'm neglecting to do in order to get the percussion MIDI file to reflect the time signature changes when I view it in the MIDI editor? That is, can the "Clip Signature" track the changes in the main arrangement?

Thanks.
