I’m trying to set up a Syphon Server within the code below (by Golan Levin). The code runs fine if I comment out the server line in void setup(), but once I try to activate the new SyphonServer I get the dreaded “It looks like you’re mixing “active” and “static” modes” error. I tried making a new method for the server, but that didn’t work. Help would be appreciated.

* Yellowtail

*
* Click, drag, and release to create a kinetic gesture.
*
* Yellowtail (1998-2000) is an interactive software system for the gestural
* creation and performance of real-time abstract animation. Yellowtail repeats
* a user's strokes end-over-end, enabling simultaneous specification of a
* line's shape and quality of movement. Each line repeats according to its
* own period, producing an ever-changing and responsive display of lively,
* worm-like textures.
