Well, not quite. Grant recently wrote:
    "Personally I find state variable filters to be completely boring.
Although the SEM used one and some people like it. For musical drama, a
Sallen-Key (Borg) or Butterworth 4 pole (Boogie) gives much better results.
Five years ago I prototyped a state variable filter made with Vactrols and
it was so 'plain vanilla' I almost cried. Painfully unexciting."
