Hey Zach, Looks like you've gone deep into it :) Sounds like those MAX macros are set because the code can't currently handle longer lists. I won't have time to look at this for a while. Could you post a bug report to the bug tracker (Help menu --> report bug) with the info in this email? Also it might be worth your while to see if anyone has tried this when using this object in Max/MSP. Its the same code.
