Hi PD list,

I have uploaded an example of the problem as about 20 rather unmusical 
seconds of me waving 1 Wiimote
as accelerometer driving frequencies of 3 [osc~], almost nothing else 
running, and no visuals, sliders, atoms:


It is panned quite left (when I use 2 Wiimotes I pan them leftish and 

Will keep breaking it down further to isolate the problem.

The patches including visuals (now disconnected) can be viewed at:
