Hello Chris,
That voicing parameter controls the overall 'strength' (amount of attenuation of each frequency) of the voicing filters, and so would affect all of the following CODM parameters:
Rank.Encl_FiltParamWhenClsdForPipeMIDINoteNum036_OverallAttnDb
Rank.Encl_FiltParamWhenClsdForPipeMIDINoteNum036_ExtraAttnAtMinDb
Rank.Encl_FiltParamWhenClsdForPipeMIDINoteNum096_OverallAttnDb
Rank.Encl_FiltParamWhenClsdForPipeMIDINoteNum096_ExtraAttnAtMinDb
For example, if the voicing parameter is set to -6 dB then the amount by which any given frequency would be attenuated would be approximately halved (compared to 0 dB).
