"Negatively Delaying" MIDI (i.e. MIDI 'play ahead')?

Hi everyone,
Is it possible to "negatively delay" certain MIDI tracks in X3? I have master and slave DAW machines, with woodwind, brass, choirs, and organs running on the slave and outputting 20 channels of autio to tracks on the master machine. There is a certain inevitable delay on those tracks because of both output latency (on the slave) and input latency (on the master).
 
I would like to be able to have the MIDI going to the slave delayed by a negative amount (so it is sent a few milliseconds earlier) to compensate for that latency. It's easier than nudging the MIDI tracks manually to the left, because that means they don't line up with the grid for quantising etc.
 
Any thoughts appreciated!
 
Cheers,
 
Martin

    You can set a positive Timing Offset (msec) in Preferences > Audio > Sync and Caching that will delay audio tracks vs. MIDI sent to external devices, effectively compensating for the MIDI and audio latency of external sources. MIDI-driven soft synths on the Master will not be affected because they are buffered up in advance and handled like audio tracks.
     
    Be aware, however, that this offset basically changes the relationship between the MIDI grid and the audio clock, which will affect how MIDI lays down when recording to the audio metronome or existing audio tracks.

    You can also set the "Time" offset in the track inspector to positive or negative values for any midi track.

    Many thanks guys! Brundlefly - I don't really want to change the relationship between the clock and the grid, so I think Dan's solution might be better for me (and can be adjusted separately on a per-track basis!).
