I can hear a faint low freq stuff on the strings one, but not the Fanfare
one,
anyway some high passing on the mixer should fix it?
 I dunno it just sounds like analog oscillators mixing together
I can hear it on my machine on the strings one, not on the Fanfare
Could be the effects ? When I turn the effects it goes away

Easily heard here. I didn't hear it on my machione, maybe your VCAs need
calibration
You can do that in the Tune page

There are slight differences in sound between units, but not drasticly
As far as the envelopes go, make sure both units have the same settings
in the engine optimiser, other than that I can't see why they would be any
different
since the envelopes are CPU generated :)
