That makes a lot of sense, thanks, I really appreciate the suggestion.

I am trying it right now:
i disabled the number boxes on the WiiOSC accelerometer patches, and 
also the sliders on my Condition patch,
and disabled visual output to sliders and L R arrays on my StereoOutput 
and the GEM windows with visuals are not open (although still "fed"),
so there is no visual output at all.

I have convinced myself that it is a bit smoother, however there are 
still some slight "crackles".

Some may be instability in the accelerometer signals from the Wiimotes,
however they look rather stable in the DarwiinRemoteOSC views.
I will report back in a few days after some more diagnostics.

Do you know whether the updates on sliders are faster than on 
atom/number boxes ?
I can live without frequent updates on the number boxes in my 
WiiOSC.pd,  however
I need at least some rapid visual diagnostics on the conditioned signals,
if the GEM monitor visuals aren't running I need the 3 Condition.pd XYZ 



If I can't make more progress I'll make some exact diagnostic audio 
recordings and examine them.
