Xpantastic!

It would not change anything adding a faster 6809 and upping the 
speed of the clocking circuit, you would have to change a lot more in 
the circuit to cope with the faster speeds.. it would also create a 
high risk of breaking things. Circuits do not like to be run at a 
faster speed than they were designed for they usually break or dont 
work at all. I would never risk this in such an expensive piece of 
kit.

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.

If you need ridiculously punchy bass, just buy a Moog Source or 
something.

Just wanted to add I'm not being mean...these things come across 
better face to face :o)
