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:
http://www.webel.com.au/project/drancing/puredata/audio/drancing.VFO.3osc.crackles.mp3
It is panned quite left (when I use 2 Wiimotes I pan them leftish and
rightish).
Will keep breaking it down further to isolate the problem.
The patches including visuals (now disconnected) can be viewed at:
