[A6] low frequency noise on key release?

[Chris Pickett]

Hi,

I noticed recently that one some patches there is a low frequency noise 
when I release a key in the lower octave of the A6.  This happens with a 
number of the available bass patches and also things like A6 Eliano.  It 
sounds similar to the noise that occurs with high up strings patches, 
but you can only hear in the lower octave and as a quick "bump" after 
you release the key.

Has anyone else noticed this, or can anyone try and confirm?  I did have 
everything tuned.  Is it possible I screwed something up by playing with 
the volume set too loud or making distorted / dying-machine kind of patches?

Thanks,
Chris
