i have never seen anything that used more than 1K events
i would die before i got to 100
You mean on one brick or on the server in general?
It's not very hard to hit 100 lines of events on one brick. You only need 10 of these bricks to hit 1000. It's not hard at all.
For example, my evented piano and harpsichords have evented songs with lots and lots of notes. The longest songs contain about 2000 notes -> 2000 eventlines.
