Odd noise?  Can you give us a definate description?  Is it a distortion type
sound?  A high pitched sound that plays along with the bass?  A click or
distorted envelope sound?

If you are listening through headphones it could just be the inability of
the headphones to reproduce some of the low frequencies which the A6 can
produce quite a bit of.  This can sound like a ringing or a distorted sound.

Try to make a bass patch that is pretty low, but use the 12db filter as a
highpass filter [on the oscillator input] and run that into the 24db filter
for finalizing the bass patch.  See if the noise becomes more prominent as
you pull the highpass down and allow more low frequencies through, and see
if it goes away as you turn the cutoff to the right slowly.
