Alesis Andromeda A6

Hello-

I seem to have discovered only two "problems" with my A6 (and 
they might just be par for the course):

1.  With the VCA envelope set with fast release times, a few 
voices release SLIGHTLY more slowly in the left audio channel 
than the right- it gives a slight stereo effect at the ends of some 
punchier sounds.  In other words, the left channel will still be 
playing for a few milliseconds after the right.  It's no big deal, but I 
wonder whether it is something fixable.  

2.  More importantly, when I tune oscillators 1 and 2 together 
VERY closely, they don't seem to "hold still;" that is, they don't 
beat against each other rhythmically, as they would in any other 
VCO based synth.  To reproduce this effect, simply set 
oscillators 1 and 2 on up saw, and then, using the fine tune 
knob(s), try to tune them together very, very finely- try to get them 
to stop "beating" against each other, and then listen- do you hear 
them "quivering" just a little bit?  

:)
Thanks in advance for any responses.
