I personally do not understand this general obsession with making
envelopes faster, the Xpander is perfection itself. It the real world
the basses sound fine, gorgeous in fact, I love them..If you are
actually sitting down with a scope analysing speeds of enevelopes on
these machines, I personally think you've lost it. You need to
actually play it more, write some songs, use it as an instrument. You
change stuff in it, you will ruin the sound I guarantee it.
One does not need a scope to experience the slow envelopes on the
Xpander, it is plainly audible.
The same goes for the OB8.
