Hi Fred,

When I first started recording my own MIDI performances some 16 or 17 years ago, I remember having exactly the same problem, that there was latency in my own performance as I was trying to record against pre-recorded accompaniment tracks. Also, when I first started testing Composer's recording, I found that my human latency was horrible. I've improved on that a good bit with practice, but still, I'm a terrible ensemble player when I play with my one-person band (multiple tracks in Composer).

Fortunately, there are easy ways to fix one's recorded human latency. You can shift the real as-performed times of selected notes to the right or left using Composer's piano roll notation. Read about this in the Help / Users Guide in the section Viewing and Editing the Music Performance / Viewing and Editing the Performance of Notes. After you shift the notes, you might want to use the Track / Re-Transcribe command so that the notated rhythms match the re-located notes.

Cheers
