Advanced Logic Pro Automation

Hi,

I'd like to use 4 audio tracks in logic and rapidly switch between each
track using mute automation. The problem though is that it is very
difficult to do this by hand in logic using track automation. For
example, it is difficult to insure that 1 tracks mutes exactly as
another track unmutes. Plus it takes ages to automate for any length
greater that a few seconds. So I was wondering if there is any way of
importing automation into logic which I could produce using a c++
program?

Thanks for your help,

Aine.
