Clip-launching-clip lag (internal MIDI routing)

[Billdesman]

Ok, I've been looking online for a while but can't find a good answer to my question. My idea is to use a dummy MIDI or Audio clip to control another MIDI or Audio clip on another channel. With control I mean launch and stop the clip. So for instance, I would have 2 channels, with an audio clip on channel one, and a MIDI clip on channel two. Then when I launch the MIDI clip, I would like for the audio clip to automatically start.

To do this, I enabled the IAC driver (I'm on Snow Leopard and have Live 7.0.18), and made a MIDI clip playing note G8. Then in the I/O, I send the MIDI to the IAC driver. I have this all set up so it will sync, and control. Then with the MIDI map, I set the audio clip to start for note G8.
So far so good. Now when I launch the MIDI clip, the audio clip also launches, but there is a significant lag (silence of 5s) before the audio clip starts, which makes it unuseable.

Now for my question. Is there something I can do to reduce the lag? Or is there an easier way of achieving my goal without the IAC driver for instance?

Thanks for all the help!!!!!

I see I put this in the wrong section. I'll add it to the right one! Sorry!
