For this recording I revoiced the Chancel Pedal, Great, Choir, Swell, Solo, Gospel and Echo divisions plus the Gallery Swell on the 1969 Schlicker organ, 146 stops total. I didn't use the 99 neo-baroque stops of the sample set for this 'romantic' music). Meanwhile I've revoiced the entire sample set.
Result: much more open and transparent and finally no problems with adding reverbs anymore. It's a (semi-) dry set. The boxiness/muddiness (over-accentuation of certain -- mostly lower -- frequencies) has disappeared and the set has become much more balanced tonally.
