maybe, I did not test it at all, so really, maybe...
the fromScript() method could be more usefull than using a setExpression()
toScript() and fromScrit should have consistent string formating behaviours
/ needs
and you should'nt have too much things to do to your string expression to
send it back
to the knob as an expression, without the offending ".left" bit.
cheers.
