Hello all,
in development of our sampleset, we have one problem with a 32'-rank (Untersatz). A few notes of the recorded lower octave sounded so bad that we decided to replace them by adjacent notes. The result was a slightly rumbling noise when playing them in Hauptwerk (in a DAW they sound clean, I have implemented a highpass-filter in advance).
Today I disabled the Harmonic Shaping Filters and suddenly the Untersatz sounds pretty good. But disabling the Filters affects the whole organ (I don't hear a difference in sound however).
Looking at the CODM I found these entries in the noise ranks (they are only there):
<HarmonicShaping_PipeMIDINoteNum036_3rdAndUpperHarmLvlAdjDb>0</HarmonicShaping_PipeMIDINoteNum036_3rdAndUpperHarmLvlAdjDb>
<HarmonicShaping_PipeMIDINoteNum096_3rdAndUpperHarmLvlAdjDb>0</HarmonicShaping_PipeMIDINoteNum096_3rdAndUpperHarmLvlAdjDb>
<HarmonicShaping_PipeMIDINoteNum036_WindModelModDepthAdjDb>0</HarmonicShaping_PipeMIDINoteNum036_WindModelModDepthAdjDb>
<HarmonicShaping_PipeMIDINoteNum096_WindModelModDepthAdjDb>0</HarmonicShaping_PipeMIDINoteNum096_WindModelModDepthAdjDb>
<HarmonicShaping_PipeMIDINoteNum036_TremulantModDepthAdjDb>0</HarmonicShaping_PipeMIDINoteNum036_TremulantModDepthAdjDb>
<HarmonicShaping_PipeMIDINoteNum096_TremulantModDepthAdjDb>0</HarmonicShaping_PipeMIDINoteNum096_TremulantModDepthAdjDb>
When I copied them into the Untersatz-Rank, the rumbling noise was gone, but the rank sounded completely different than before. The manual says: "The filter behaves roughly like a high or low-pass filter, with the gain for frequencies above the third harmonic being as nearly as possible the same as for the third harmonic."
What is the best approach to resolve this issue?
1. Disable the Harmonic Shaping Filters for the whole organ (wind model is enabled) or
2. Copy the entries into the CODM of the Untersatz and risk a completely different sounding stop (or what are the best values to avoid sound differencies).
I hope you understand what I mean. Thanks in advance.
