Are you using Logic 5 Ambi? If not, you are pretty much out of luck. Logic (until version 5) has seriously lacked in the automation department. If are using Logic 5, go to the view menu while in the arrange window and select Track Automation. The tracks will become like 3 times bigger in the arrange window, and on the left side where the track MUTE/SOLO buttons are, there will be 3 new boxs. The first one will be where you can select which, envelope/MIDI CC value you want to automate. Below that on the left is a box marked off (by Default), click on this to view the 5 realtime automation controls (Touch, latch etc.) and next to this box is the value box for the selected envelope. Oh and the little arrow next to the Realtime automation selection box, will allow you to display the selected envelope for the next track down as well (Real handy for setting up pan and volume changes real quickly for multiple tracks).
