Hi RLW, The problem you wrote about is something I just recently became aware of. It has nothing to do with the power of your computer or the number of tracks. Here's the deal... With 10.3.2 the Scripting feature is experiencing a "regression" to a version of Logic (10.3.0) where a bug affected the operation of the Scripters, producing the behavior you described. At the time of the 10.3.0 release I issued a notification to my customers, including a way to fix it. The bug was then fixed in 10.3.1, but now (GAH!) it's back in 10.3.2. The good news is that there's a pretty easy fix for this. Please write to me at support =at= skiswitcher =dotcom= and I'll tell you how to solve the issue.
