Dear Darryl,
Thanks for this interesting article.
I have avoided playing around with the voicing since it has always seemed to me to be a good way of spending an awful lot of time getting into a real pickle. Your advice tempts me to have a go, particularly as my (smallish) room has several troublesome resonances I would like to deal with.
Thinking about it, having identified which particular notes are causing problems would it be possible to semi-automatically level these notes across all ranks of the same pitch? I realise that the harmonic content of ranks of the same pitch differs somewhat (otherwise they wouldn't be different ranks) but as a first approximation it would save a lot of time.
In effect, this would be a 'by note' voicing rather than 'by pipe'.
Nick
