About one in five midi notes are missed in the recording of my midi drums even though they are synthesized correctly when passed straight to a virtual instrument. It is VERY annoying. A screenshot of a few hits on a Kat pad is attached. The midi notes are recorded on the first track, and on the second track they are passed into a drum input plugin. As you can see, two notes are not recorded in the midi track (3rd and 9th) even though the are recorded in the audio track.
